Any of the eight large celestial bodies in the solar system that revolve around the sun and shine by reflected light; Mercury,Venus,Earth,Mars,Jupiter,Saturn,Uranus and Neptune;In order of proximity to the sun;Viewed from the constellations Hercules,all the planets rotate around the sun counterclockwise direction.
Now im going to tell you some individual information about each of the eight planets.The information is going to include the radius,volume,length of day ect.
Mercury is the smallest and innermost planet in the Solar System. Its orbital period around the Sun of 88 days is the shortest of all the planets in the Solar System. It is named after the Roman deity Mercury, the messenger to the gods.
