Mercury

(inner-most and smallest planet in the solar system)

Mercury is the nearest solar system planet to the Sun and the smallest. Characteristics:

It has no moons. It is a rocky planet with virtually no atmosphere, but has a magnetic field that was not expected. It was also thought to be tidally locked to rotate once per orbit, but in fact rotates 1.5 times per orbit.

Two NASA spacecraft have visited: Mariner 10 flew by and MESSENGER orbited it for over 10 years. A current ESA/JAXA mission, BepiColombo was launched in 2018, aiming to reach Mercury in 2025.
