Description: Mercury is the smallest planet in the Solar System and the closest to the Sun. The planet is in synchronous rotation with the Sun with the surface temperature reaching 700K in the day and dropping to 100K at night. Mercury is too small and hot for its gravity to retain an atmosphere making the planet a dead, silent planet.
