Mercury (planet)

Mercury as seen from orbit

Mercury (also known as Sol I) is the first, and smallest, planet in the Sol system.

Having only a minimal atmosphere, and orbiting Sol at a distance of just 0.39 astronomical units, (88-Earth-days cycle) temperatures on the Mercurian surface range from 100 to 700 Kelvin.
This is due to the small, rocky body's close location to the Sun, which precludes any semblance of a lifeform-supporting planetary atmosphere.

According to star charts, Mercury is classified as a B-class planet. This planet was a charter member of the United Federation of Planets in 2161.

Mercury rotates in a way that is unique in its Solar System. It is tidally locked with the Sun in a 3:2 spin–orbit, meaning that it rotates on its axis exactly three times for every two revolutions it makes around the Sun. As seen from the Sun, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two Mercurian years. An observer on Mercury would therefore see only one day every two Mercurian years.

Since it is uninhabited, by 2166, humanity had established multiple industrial antimatter generators on this planet.
