Mercury
Type:	Planet
Location:	Sol system Alpha Quadrant

Mercury (or Sol I) was the first planet in the Sol system and was named after the Roman god Mercury, the envoy of the gods according to Earth mythology.

It had only a minimal atmosphere and orbited Sol at a distance of just 0.39 astronomical units, temperatures on the Mercurian surface ranged from −183 °C to 427 °C.

In 1969, the USS Enterprise passed Mercury as it attempted a slingshot effect around Sol in an effort at returning to 2267. When the Enterprise passed this innermost planet, the gravitational pull of the star increased. (TOS: "Tomorrow is Yesterday")

Later that year, Mercury was seen on a map depicting the Sol system. This map was scanned by Nomad. (TOS: "The Changeling")

Mercury was featured in an amusing story a holographic Doctor Stephen Hawking told his holographic poker partners Albert Einstein and Sir Isaac Newton and Data. He said that "in that frame of reference the perihelion of Mercury would have precessed in the opposite direction!" Albert Einstein found this "a great story"; Sir Isaac Newton, however, did not understand the joke. (TNG: "Descent")

In the The Adventures of Captain Proton holoprogram series, Mercury was controlled by Doctor Chaotica. When he tried to conquer Earth, he claimed that those who oppose him "will face a dire fate as slaves in the mines of Mercury." (VOY: "Bride of Chaotica!")
