How did mecury get named?

Answer 1

It has been the tradition of the scientific community to name objects of the Solar System after Roman gods and goddesses, since that is what they were originally thought of as being by Roman and Greek observers. Mercury is the messenger Roman God, and with winged sandals was the fastest of all the Gods. When the planet was observed, it was noted how quickly the planet moved across the sky. (It is closest to the Sun and has a quicker orbit.) Therefore, it was named after the fastest God, Mercury.

Answer 2

Mercury was named after the Roman god of commerce, travel, and communication. The planet's fast orbit around the sun was thought to symbolize the god's speed and agility. The name was officially adopted by the International Astronomical Union in the 19th century.
