A lot has been discovered about Neptune since its initial sighting in 1846. The Voyager 2 spacecraft, on Aug 25, 1989, did a fly by of this blue celestial giant and sent back some photos and other data that has helped the science community understand more about the last planet on the block. Here are some interesting factoids about Neptune:
8th Planet from the sun
Named after the Roman god of the oceans, Neptune
Has rings…just like all the other gaseous giants
2.68 BILLION miles from Earth at its closest point in orbit
60,190 Earth days (164.8 Earth years) for Neptune to orbit the sun once!!
Looks cool…because it is VERY cool…as in cold -330F (72 Kelvin)…(-201 C for the non-US friends of the Science Museum of Virginia)…brrr!
After 2006's demotion of Pluto, this blue gaseous giant became the last official planet in our solar system.
