Mercury, being the closest to the Sun, with a weak magnetic field and the smallest mass of the recognized terrestrial planets, has a very tenuous and highly variable atmosphere (surface-bound exosphere) containing hydrogen, helium, oxygen, sodium, calcium, potassium and water vapor, with a combined pressure level of about 10 −14 bar (1 nPa ).

Mercury (0.31–0.59 AU from the Sun) is the smallest planet in the Solar System. Its surface is greyish, with an expansive rupes (cliff) system generated from thrust faults and bright ray systems formed by impact event remnants. In the past, Mercury was volcanically active, producing smooth basaltic plains similar to the Moon.
The first probe to visit Mercury was Mariner 10. View of Mercury from Mariner 10 in March 1975. The exploration of Mercury has a minor role in the space interests of the world. It is the least explored inner planet. [1] As of 2015, the Mariner 10 and MESSENGER missions have been the only missions that have made close observations of Mercury.
