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 unexpected. It was 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 new ESA/JAXA mission, BepiColombo will be launched in 2018 to reach Mercury in 2025.
