Introduction The planet Mercury is very difficult to study from the Earth because of its proximity to the Sun. It is the second smallest planet (it was believed to be the smallest until the discovery that Pluto is actually much smaller than originally thought), and also the fastest in its orbit since it is the innermost planet. Solar System Records Highest uncompressed density. Highest diurnal variation in temperature. Only Solar System object with a 3:2 spin-orbit resonance. it rotates on its axis exactly three times for every two revolutions it makes around the Sun Geological history ended the earliest among terrestrial planets. Smallest planet with global magnetic field. Most Earth-like magnetosphere. Name Named after the Roman messenger god who was known for his ability to travel quickly with wings on his feet. Mercury travels in orbit the shortest time of all planets Distance From The Sun Mercury is located 57, 910, 000km (0.38AU) from the Sun. Mercury is the inner most planet in our solar system. Orbit The orbit of Mercury is the most eccentric of the planets in the solar system. At perihelion it is 46,001,200km from the Sun At aphelion it is 69,816,200km from the Sun A difference of 23,815,700km giving it an eccentricity of 0.21 Orbit Mercury is the only object Solar System with a 3:2 spin-orbit resonance. This means it rotates on its axis exactly three times for every two revolutions it makes around the Sun The length of a day on Mercury 58.63 Earth days.
