On July 12th!
It will be the first time since it's discovery by Johann Galle in 1846 that Neptune will have made one full orbit of the sun. It's orbital period is 164.79 years.
Neptune has always intrigued me since it was the first planet to be discovered by mathematical prediction thanks to the work of both John Couch Adams and Urbain Le Verrier independantly of each other performing calculations after observations indicated that there must have been another gravitational force perturbing the calculated orbit of Uranus.
I also think it is brilliant evidence of how young astronomy is as a science and yet how far our understanding of the solar system and the wider universe has come in the time it takes Neptune to make one orbit!
