}}'''Neptune''' is the eighth and farthest true [[planet]] from the [[sun]]. Long after its discovery, [[astronomy|astronomers]] had no notion of how remarkable Neptune would prove to be, until [[Voyager 2]] flew by Neptune in 1989. Neptune continues to perplex astronomers, and yield more evidence for a young solar system, with virtually every observation made.
