Mercury is the planet closest to the Sun and the least explored. It is very difficult to study from Earth due to its proximity to the Sun, which means it never gets more than 28 degrees from the Sun's glare. Mercury is the smallest planet and fastest planet in its orbit, taking 88 days to revolve around the Sun. The Mariner 10 spacecraft was the first to visit Mercury in 1974 and photographed nearly half of its surface, finding a landscape scarred by impacts and wrinkled with great ridges.

The planet Mercury is very difficult to study from the Earth because of its proximity to the Sun. It is the second smallest planet and also the fastest in its orbit since it is the innermost planet.
Mercury, The Innermost Planet Mercury is one of the least explored planets in the Solar System. -Makes it hard to observe because it NEVER gets more than 28尊 from the Suns glare.
Mercury OrbitMercury Orbit Earth The Innermost Planet 35,983,095 miles from the Sun on the average. It revolves about the Sun once every 88 days in an orbit that is the most elliptical of any planet except Pluto. Venus Mercury Sun

Mariner 10Mariner 10 Mariner 10 flew over Mercury at an altitude of 756 km on in March 1974. It took many photographs of the surface of Mercury. Its photographs cover nearly half (the other half is unexplored) the surface area of the planet Mercury.

Information on MercuryInformation on Mercury Mercury A planet of extremes Mercury is a lump of rock, barely larger than the Moon, living under the fierce heat of the burning Sun. It experiences extremes in temperature from over 400属C at noon to less than -150属C at night.
Information on MercuryInformation on Mercury On the surface Mercury is very similar to our Moon, a battered world, scarred by aeons of impacts by meteorites. The surface is also wrinkled, with great ridges hundreds of kilometers long called scarps, which probably appeared when Mercury cooled and shrunk soon after it formed.
Inside of Mercury is more like the Earth. It has a core made of iron, and the centre may be molten, kept hot by radiation deep within the core.
3:2 Orbital Resonance Mercury is tidally locked to the Sun Similar to the way the Moon is tidally locked with the Earth After one orbit around the Sun (88 days), the planet has rotated on its axis 1.5 times It then takes two orbits for Mercury to rotate three times!
Artists rendition of MercuryArtists rendition of Mercury From Mercury, the Sun appears two and a half times larger than it does on Earth. The sky would appear black because there's little atmospheric scattering of light. One would be able to see two bright "stars," possibly discernible as cream-colored Venus and blue-colored Earth.
MESSENGER, launched Aug. 3, 2004, is only the second U.S. spacecraft sent to the planet, and it will be the first to establish an orbit. Messenger will enter Mercury orbit on 30th September 2009, and complete its mission one year later.

Editor's Notes

  1. http://csep10.phys.utk.edu/astr161/lect/mercury/mercury.html
  2. http://csep10.phys.utk.edu/astr161/lect/mercury/features.html Because of its close proximity to the Sun, Newtonian gravity doesnt quite work and general relativity is needed to explain some of the aspects of Mercurys orbit. In fact, this was one of the first tests of general relativity. Previously and second planet (Vulcan) was thought to explain the discrepancy. Anyway, this is an interesting aspect that should be included in this presentation.
