The Planets
A planet is a celestial body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, but is not massive enough to cause thermonuclear fusion. It has cleared its neighboring region of planetesimals. The term planet is ancient, with ties to history, science, mythology, and religion. The planets were originally seen by many early cultures as divine, or as emissaries of the gods. The names of the planets (except the Earth's name) are related to this past of "gods" :
