neptune will complete its 165 years orbit of the sun.well if it take 1 year for the earth to orbit the sun then it takes neptune 165 years.kind of amazing I think.make us realize that we're not alone.
in reference to:"And for those of you who still think of Pluto as a planet, waiting around for its 248 year orbit to return it to its position at the time of its discovery won't happen until 2178! It's taken us a long time to learn so much about where we live in this Universe, so don't forget this remarkable anniversary!"
