Neptune was discovered in 1846 and is the farthest planet from the Sun (after Pluto was demoted to being a “dwarf Planet”). To find Neptune in the night sky you would need a telescope or a good set of binoculars as it is extremely dim. In fact Galileo observed Neptune between 1612 and 1613 but mistook it for a dim star.
