What is there to know about planet Mercury?

Answer 1

The Romans named the planet after the fleet-footed messenger god Mercury, probably for its fast apparent motion in the twilight sky. The astronomical symbol for Mercury,

is a stylized version of the god's head and winged hat atop his caduceus, an ancient astrological symbol. The Greeks called it Stilbon ("the gleaming") and Hermaon. Before the 5th century BC, Greek astronomers believed the planet to be two separate objects: one visible only at sunrise, the other only at sunset. In India, the planet was named Budha , after the son of Chandra (the Moon). The Chinese, Korean, Japanese, and Vietnamese cultures refer to the planet as the water star , based on the Five Elements. The Hebrews named it Kokhav Hamah , "the star of the hot one" ("the hot one" being the Sun). Mercury is smaller than several of the natural satellites or moons in our solar system.
