First discovered through mathematical calculation, Neptune was later spotted through a telescope in 1846 by German astronomer Johann Galle. Scientists estimate Neptune formed roughly 4.5 billion years ago by gravitys pull of swirling dust and gas. Once Pluto was demoted to dwarf planet status, the cold, icy Neptune officially became the most distant planet from the sun.
