This document provides an overview of the Moon including its location, physical characteristics, surface features, phases and movements. Key details include that the Moon is Earth's only natural satellite, has no atmosphere or liquid water, and its surface contains craters, highlands, and low-lying volcanic plains called maria. The Moon revolves around Earth every 27 days while rotating on its axis in the same time, keeping the same hemisphere facing Earth. Its phases are caused by the varying illumination of its surface from Earth's perspective over the course of its revolution.

The document discusses the phases of the moon. It explains that the moon appears to have phases because it revolves around Earth while also rotating on its axis. As the moon orbits Earth in its elliptical path, the angle of the sunlit side facing Earth changes, leading to different portions being illuminated and visible from Earth over the course of a lunar cycle. The document outlines the eight main phases of the moon - new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent - and provides a brief description and illustration of each phase.Our moon

The Moon is Earth's only natural satellite. It orbits Earth approximately every 27 days and was formed from debris after a Mars-sized object collided with Earth. The Moon has no atmosphere and experiences extreme temperature ranges. Its surface features include mountainous highlands, flat plains called maria formed by ancient lava flows, and large impact craters. Future plans may include establishing a lunar base to support long-term human exploration and utilization of the Moon.Phases of moon

The document discusses the phases of the Moon as seen from Earth. It explains that as the Moon orbits Earth over the course of about 27 days, we see it go through phases from New Moon to Full Moon and back to New Moon again. These phases include the crescent moon, first quarter moon, waxing and waning gibbous moons, and last quarter moon. The illuminated portion of the Moon changes depending on where it is in its orbit relative to the Earth and Sun.Phases of the moon

The phases of the Moon are caused by the Moon orbiting the Earth while the Moon and Earth both orbit the Sun. The different phases are: new moon, first quarter, full moon, and third quarter. As the Moon revolves around the Earth over approximately 28 days, the angle of illumination by the Sun changes, resulting in different portions of the Moon appearing lighted from Earth's perspective.Phases of the_moon

The document discusses the phases of the moon. It explains that as the moon orbits the Earth over 28 days, the angle of illumination changes from our perspective, causing it to appear to go through eight phases from new moon to full moon and back again. These phases include the waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent. Diagrams and a modeling activity are provided to illustrate how the changing positions of the Earth, moon, and sun cause the moon to appear to change shape over the course of its orbit.Phases of the moon

The phases of the Moon are caused by the Moon revolving around the Earth and reflecting sunlight towards our planet. Half of the Moon is always lit, but we only see the lit portion facing Earth, which changes throughout the Moon's orbit. There are eight phases that occur in a repeating cycle as the illuminated area of the Moon appears to grow and then shrink over the course of around 29.5 days.Moon

The document discusses key facts about the moon, including that it orbits Earth and reflects sunlight from its surface. It also explains the phases of the moon, which are caused by the moon orbiting Earth as the sun lights different parts of its surface over the course of about 29 days. The moon's gravitational pull causes ocean tides on Earth. Diagrams show each moon phase as the portion of the lit surface visible from Earth changes from new to full to new again in a repeating cycle.Earth Moon And Sun

The document describes the relative sizes and motions of the Earth, Moon, and Sun as seen from Mars. The Earth and Moon are spherical, and the Moon is about 1/4 the size of Earth. The Moon orbits Earth every 28 days and Earth orbits the Sun every 365 days. The Sun is about 110 times bigger than Earth and appears to move across the sky and rise in the east and set in the west, causing the cycle of night and day.Phases of the moon (Teach)

The moon goes through eight phases in a cycle that repeats every 27 days and 8 hours. The phases are caused by the changing orientation of the moon in relation to the Earth and sun, and the amount of sunlight that reflects off the moon's surface and is visible from Earth. The moon does not produce its own light but shines due to reflected sunlight. The document discusses the moon's phases and cycle, how its appearance changes nightly, and how the moon rotates to always keep the same face toward Earth.4 14 2017 moon phases notes

The document discusses the phases of the moon and eclipses. It begins by explaining the different phases of the moon including new moon, crescent, quarter, gibbous, and full moon. It then discusses that the moon orbits the earth about once a month. Solar eclipses occur when the moon passes between the earth and sun, blocking the sun's light. Lunar eclipses occur when the earth passes between the sun and moon, and the earth's shadow falls on the moon. For an eclipse to occur, the moon must be new or full, and its orbit must be aligned with the earth and sun.Phases of the moon

The document describes the eight phases of the moon:
1) New moon - When the moon is between the sun and earth so we cannot see it.
2) Waxing crescent - After a few days we can see half of the illuminated side of the moon.
3) First quarter - Half of the moon is illuminated after about a week.
4) Waxing gibbous - More than half is illuminated two or three days after the first quarter.
5) Full moon - The entire near side is illuminated about two weeks after the new moon.Life without the Moon

If the Moon suddenly vanished:
- Earth's axis would lose stability and wobble dramatically, causing extreme temperature changes and unpredictable seasons.
- Tides would be much smaller, caused only by the Sun, disrupting marine life and coastal ecosystems.
- Earth's rotation would speed up, with day lengths shortening to 8-10 hours and winds of 160-200 km/h sweeping the surface.
- Life on Earth would struggle to adapt to the entirely different environmental conditions without the stabilizing influence of the Moon.The moon

The Moon orbits Earth and reflects sunlight, which causes its phases to appear to change over the course of a lunar month as the illuminated portion changes from new to full and back to new. The Moon's gravitational pull, combined with the Sun's, causes two high and two low ocean tides each day. The greatest difference between high and low tides occurs during full Moons and new Moons, when their combined gravitational pulls reinforce each other.Earth, Sun, Moon Rotation Flipbook

The moon is tidally locked to Earth, meaning the same side always faces Earth. This is why there is a big difference between the appearance of the near side, which faces Earth, and the far side. The near side has many visible maria (dark plains) while the far side has fewer maria and a thicker crust with more craters. Additionally, the Earth and moon orbit a common center of gravity called the barycenter, located about 900 miles from Earth's surface. Both bodies revolve around this point, which itself revolves around the sun.Our moon

It explains that the Earth's rotation on its axis causes day and night, with a full rotation taking 24 hours. It also explains that the Earth revolves around the Sun over the course of 365 days, which divides the year into four seasons due to the tilt of the Earth's axis. Finally, it discusses how the Moon revolves around the Earth over 29 days, and how the changing positions of the Sun, Earth, and Moon cause the Moon's phases.Phases of the moon

The document describes key facts about the Earth, moon, eclipses, and lunar landforms. It states that the Earth orbits the sun in an elliptical path and rotates on its axis, causing day and night. The moon revolves around the Earth while the same side always faces it. Solar eclipses occur when the moon blocks the sun, and lunar eclipses happen when the Earth blocks the sun from the moon. Common lunar landforms include craters, maria (areas of hardened lava), and ray craters.

The document summarizes key concepts about the Earth, moon, sun, and universe. It describes how the Earth rotates daily and revolves yearly around the sun, causing day/night and seasons. It also discusses the moon's phases, tides, and eclipses due to the positions of the Earth, moon and sun. Finally, it briefly outlines historic models of our solar system and discoveries about gravity and our sun.Astronomy lunar phases eclipses and tides

The phases of the moon are caused by the changing positions of the sun, Earth, and moon relative to one another. A new moon occurs when the moon is between the Earth and sun so its night side faces Earth. A full moon happens when the moon is on the opposite side of Earth from the sun, so its full day side faces Earth. Eclipses occur when the sun, Earth, and moon align so that one passes in front of the other, casting a shadow. Lunar eclipses happen during a full moon when Earth blocks the sun's light from reaching the moon. Solar eclipses occur during a new moon when the moon passes between the sun and Earth, casting its shadow on Earth. The moonEarth's moon

The document discusses key characteristics and features of Earth's moon. It describes how the moon rotates on its axis once every 29.5 days and revolves around Earth, also taking 29.5 days. This locked rotation is why we always see the same face of the moon. The changing positions of the moon and sun relative to Earth cause the phases of the moon and create high and low tides. Eclipses occur when the moon or Earth block the sun's light. Craters and flat dark areas called maria are visible features on the moon's surface.Earth's moon

The moon rotates on its axis once every 29.5 days and revolves around Earth once every 29.5 days, keeping the same face pointed towards Earth. The changing positions of the moon relative to Earth and the sun cause the phases of the moon and tides on Earth. Features on the moon's surface include craters and flat dark areas called maria, which are large basins filled with hardened lava.Astonishing Astronomy 101 - Chapter 1

The document summarizes key features of the lunar landscape as observed from Earth. It describes light and dark colored areas on the moon's surface, including craters formed by impacts, large flat dark areas called maria formed by ancient lava flows, mountains around the edges of maria, and older highlands near the lunar poles with more craters. It also discusses lunar phases caused by the changing orientation of the moon as it orbits Earth, solar and lunar eclipses, and tides caused by the gravitational pull of the moon and sun.More from Oyster River HS (13)

The unaided human eye can see about 6,000 stars on a clear night, with about 3,000 stars visible at any given time. However, light pollution limits the number of visible stars to a few hundred for most locations. The apparent brightness of celestial objects is measured on the magnitude scale, with 1st magnitude stars being the brightest and 6th magnitude stars being the faintest visible to the unaided eye. Constellations help organize the sky into defined regions, though the stars within a constellation may be located at different distances.Blackholes

The document summarizes what is known about black holes, including:
- Einstein's theory of general relativity predicted black holes could exist, though they were not believed to be real until convincing evidence in the 1970s.
- Black holes are extremely dense regions with gravity so strong that not even light can escape, where the escape velocity exceeds the speed of light.
- Observational evidence like hot material falling into black holes and jets of glowing gas have shown that while invisible, black holes' effects can be observed and they are widespread throughout the universe.Other solar systems (12/16)

There are currently 424 known exoplanets orbiting stars other than the Sun. The first exoplanet was discovered in 1992 using pulsar timing and the first using the radial velocity method was 51 Pegasi b in 1995. There are several methods used to detect exoplanets including astrometry, radial velocity, microlensing, timing, and transit. The radial velocity method detects variations in a star's spectral lines caused by the star moving due to gravitational influences from planets. This allows scientists to calculate planetary properties. The transit method detects dips in a star's light curve when a planet passes in front of it, allowing the determination of planetary properties. As of December 2010, there were 510 known planetary systems using various detection methods.Magnetic sun

The document summarizes key facts about the Sun:
1) It is a giant ball of hot ionized gas composed primarily of hydrogen and helium that generates its own energy through nuclear fusion reactions at its core.
2) Features like sunspots and solar flares are driven by the Sun's powerful magnetic field, which undergoes a cycle of strengthening and weakening every 11 years.
3) Looking at the Sun in different wavelengths reveals layers with varying temperatures, from the visible photosphere to the super-hot corona visible in X-rays.Wtlftm dec 2010

This document summarizes the history of planetary classification in our solar system. It describes how ancient cultures knew of 5 planets and how discoveries in the 18th century expanded the solar system to include Uranus. Neptune was discovered in 1846 based on orbital anomalies. Pluto was discovered in 1930 and became the ninth planet. In 2006, the IAU defined planets and established a new category of "dwarf planets", reclassifying Pluto due to its small size and orbital properties. This reduced the number of planets from 9 to 8 and established 3 dwarf planets including Pluto, Ceres, and Eris.Solar system classification

The document discusses the classification of objects in our solar system. It describes the various families of objects based on their size, composition, and orbits. Over time, our understanding of these families has changed, particularly our classification of Pluto. New discoveries of objects in the Kuiper Belt that are similar in size and composition to Pluto caused the International Astronomical Union to reclassify Pluto as a dwarf planet in 2006 rather than a full planet.Mechanics of solar system part i

This document provides an overview of key concepts and figures in understanding the mechanics of the solar system. It defines terms like inferior planet, superior planet, and conjunction. It discusses astronomers like Aristotle, Ptolemy, Copernicus, Tycho Brahe, Kepler, and Galileo and their contributions to developing the heliocentric model of the solar system. Kepler's laws of planetary motion established that planets orbit in ellipses with the Sun at one focus and that their orbital periods are related to their average distances from the Sun. The document promises to discuss Newton and Einstein's further contributions in a future part.What is a planet

- The document discusses the history of planetary classification and discovery in our solar system. It describes how ancient cultures knew of 5 planets and how more were discovered over time, growing the solar system to 8 planets.
- In 2006, the IAU defined criteria for what qualifies as a planet, reclassifying Pluto as a "dwarf planet" since it did not meet the criteria of "clearing its orbit". This controversial move demoted Pluto from the 9th planet.
- The definition added two new dwarf planets, Ceres and Eris, and the solar system was now said to have 8 planets and 3 dwarf planets.Solar system classification

1) Early civilizations made observations of celestial objects to predict seasons and aid in navigation. The geocentric model proposed by Aristotle placed Earth at the center of the universe.
2) Planets were observed to move irregularly compared to other celestial bodies. Ptolemy proposed epicycles to explain retrograde motion within his geocentric model.
3) Copernicus suggested a heliocentric model where Earth and planets orbit the sun. Galileo's observations with a telescope supported this model.
4) Kepler developed his laws of planetary motion describing elliptical orbits with the sun at one focus. Newton later described universal gravitation explaining the forces at work.Constellations

1) On a clear night, the unaided human eye can see about 6,000 stars, though light pollution limits this to a few hundred in urban/suburban areas.
2) Constellations originally referred to patterns of the brightest stars representing mythological figures, though today they are defined regions of the sky regardless of star brightness.
3) The apparent motion of stars is caused by the Earth's rotation on its axis and revolution around the Sun, making some stars appear to rise and set daily or be visible only seasonally.Moon
