Neptune was found in 1846. on september 13 and was the first planet to be found my mathematical deduction rather than to be by telescopically sighting. Neptune can fit 17 times the mass of earth and is slightly bigger than Uranus which is 15 times the mass of earth. Neptune revolves around the sun in an almost perfect circle. It takes 164.79 earth years to orbit the sun once, and this is the length of neptunes year. The sun's strong gravity keeps Neptune revolving around it. Because it's axis is tilted, Neptune has four seasons as it revolves around the sun. Each season is about 41 years long. Astronomers have not found changes on Neptune that are caused by the seasons. People in ancient times did not know about the planet Neptune, which was discovered in1846. Before Neptune was discovered ,astronomers were finding that the planet Uranus did not go where they thought it should, as it moved among the stars. Some of them decided an unknown planet must be affecting uranus's orbit. John Adams and urbain Leverrier worked out where the unknown planet should be in the sky. When johann Galle searched in these places with a telescope, he found Neptune.
