Mercury is the smallest planet in the solar system and is the closest to the sun. The orbital period is 87.975 days. The rotation of Mercury is tidally locked with the sun in a 3:2 spin-orbit resonance.

Mercury is a rocky planet appearing much like the moon and has virtually no atmosphere (none is modeled in Orbiter), and has no natural satellites.

Mercury was visited in 1974 and 1975 by Mariner 10 in two flybys and was again visited by MESSENGER spacecraft orbiting Mercury from 2011 to 2015 when it was deorbited. There is a plan for the BepiColombo spacecraft to visit in 2025.

Physical and orbital characteristics

Mercury is the smallest planet in the solar system having a mass in Orbiter of 3.30188×1023 kg, about 1/18 that of the earth. It's mean radius is 2440 km. Its rotation is tidally locked to its orbit such that for every two orbits, it rotates three times. An observer on the surface of Mercury would experience one day every two mercurian years.

Mercury's orbit is the most eccentric of all the planets at 0.20563, and the inclination of its orbit is the highest at 7°.
