Stars are made of plasma. Lunar scientist Barbara Cohen explains how our moonfunctions very much like a planet. A planet is an astronomical body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and according to the International Astronomical Union but not all planetary scientists has cleared its neighbouring region of planetesimals.The term planet is ancient, with ties to history, astrology, science, mythology, and religion.
