SOLAR SYSTEM

Detailed explanation-1: -The ice giant Neptune was the first planet located through mathematical calculations. Using predictions made by Urbain Le Verrier, Johann Galle discovered the planet in 1846. The planet is named after the Roman god of the sea, as suggested by Le Verrier.

Detailed explanation-2: -Neptune was the first planet to be discovered by using mathematics. After the discovery of Uranus in 1781, astronomers noticed that the planet was being pulled slightly out of its normal orbit.

Detailed explanation-3: -using only mathematics-a pivotal event in the history of astronomy. Neptune, whose existence was visually confirmed in 1846, was the first planet to be discovered by mathematical rather than observational means.

Detailed explanation-4: -The only other planets which have been discovered are Neptune and Pluto. These were predicted using ingenious mathematical arguments based on Newton’s laws of gravitation and then observed near their predicted locations. In fact Neptune could have been discovered without the mathematical arguments.
