How to recognise Neptune
The most distant planet. Neptune is far too faint for the naked eye and needs a telescope or good binoculars. With a telescope it's a tiny blue-grey dot. Finding it takes a detailed chart and patience.
Neptune was found by mathematics before anyone saw it: its position was predicted from the way it tugs on Uranus. Opposition is the night Neptune sits opposite the Sun in our sky: it rises at sunset, stays up all night and is at its closest and brightest.
