The Solar System slideshow gives solid yet general notes on our solar system. It defines geocentric and heliocentric models and explains why the planets orbit the sun. It tells where our solar system is within the universe. It gives a general overview of each planet denoting the differences of inner planets and outer planets. It is an excellent introduction to any solar system unit.

Our Solar System Created by Marie @ thehomeschooldaily.com
The Solar System is made up of the sun and other celestial bodies that orbit the sun. These bodies include 8 planets, dwarf planets, over 100 moons, and countless asteroids, comets, and meteoroids.
Our solar system is found in the Milky Way Galaxy. The sun is one of billions of stars in this spiral galaxy. The sun is a medium sized star. It is our source of energy, light, and heat.
There have been two ways of thinking about how the Earth and other planets move in space. One is called a geocentric model and the other is called a heliocentric model.
At one time, a scientist named Aristotle made claims to a geocentric model. A geocentric model states that the Earth is the center of the universe and that all celestial bodies orbit the Earth.
It wasnt until after Aristotles death that a monk named Nicolaus Copernicus revealed a heliocentric model. A heliocentric model states that the sun is at the center of the solar system and all celestial bodies orbit it.
Planets orbit the sun because of gravity. Objects that have more mass have more gravity. Gravity also gets weaker with distance. The Sun and planets to scale. Credit: Illustration by Judy Schmidt, texture maps by Bj旦rn J坦nsson Gravity is the force of attraction that all objects with mass have between each other.
An animation of gravity at work. Albert Einstein described gravity as a curve in space that wraps around an object such as a star or a planet. If another object is nearby, it is pulled into the curve. Image credit: NASA The sun makes up 99% of the mass of our solar system. It has more gravitational pull than anything else in our solar system. This gravitational pull and the speed at which the planets are moving keep the planets in orbit.
In our solar system, each of the 8 planets revolve around the sun in elliptical orbits. An elliptical orbit is an oval shaped path that a celestial body takes around another celestial body.

The 8 planets can be divided evenly into 2 groups, the inner planets and the outer planets. Jupiter Saturn Uranus Neptune Mercury Venus Earth Mars INNER PLANETS OUTER PLANETS
Mercury, Venus, Earth, and Mars make up the inner planets. They are also called terrestrial planets. Terrestrial planets have solid surfaces that are comprised mainly of rocks and metals. MERCURY VENUS EARTH MARS
Mercury Closest planet to the Sun Speediest Planet- moves 30 miles a second! Thinnest Atmosphere Planet of extreme hot and cold temperatures Smallest planet 2nd most dense No satellites A satellite is an object that orbits a larger object. Example: Moon
Venus Nicknamed Morning Star and Earths Twin One of the brightest objects in the sky due to its reflective clouds Thickest atmosphere causes the Greenhouse Effect Hottest planet Retrograde Rotation- rotates backwards No satellites It is called Earths twin because they are relatively the same size.
Venus' hot temperature is due to what we call "the Greenhouse Effect." The large amount of carbon dioxide in Venus' atmosphere acts like a blanket. The heat gets trapped underneath the thick layer of clouds. Because the heat has nowhere to go, Venus gets hotter and stays hot.
Earth Most dense planet Has seasons Atmosphere with water and air Has life including humans, plants, and animals 1 Revolution= 1 year 1 Rotation= 1 day 1 satellite A revolution is one trip around the sun. A rotation is one complete turn on a planets axis.
Mars Nicknamed Red Planet due to the iron oxide (rust) on its surface Polar caps at the poles Seasons just like Earth Largest known volcano called Olympus Mons Huge canyon known as Valles Marineris 2 satellites The icecaps are made of dry ice (frozen carbon dioxide) and small amounts of water.
Asteroid Belt Asteroids are rocks and dust that are too small to be considered planets. Asteroids in the belt orbit the sun. The asteroid belt separates the inner planets from the outer planets. It is lies between Mars and Jupiter.
The outer planets are also called gas giants. Gas giants are much larger than terrestrial planets. They are comprised primarily of gases, liquids, and ice. JUPITER SATURN URANUS NEPTUNE
Jupiter Largest Planet Made up mostly of hydrogen and helium Faint ring system Has more than 75 satellites Has a Great Red Spot that is an ongoing storm Jupiter is so BIG that all the other planets could fit inside it!
Saturn Least Dense Planet Spectacular rings made of ice and dust Second largest planet Has more than 80 satellites Despite Saturns size, it could float in a bathtub of water!
Uranus Rotates on its side and east to west Blue color from methane in atmosphere 13 dark rings Thought to have oceans of water, ammonia, and methane above a solid core Has more than 27 satellites
Neptune Most distant planet from the sun Dark, cold, and windy 6 Faint Rings 13 known satellites Visible Clouds Blue color is from methane in the atmosphere
The Bible tells us in Genesis 1:1 that on the first day of creation, God created the heavens and the earth. On day 4 of creation, God created the sun, moon, and stars.
