How Close Is Neptune To The Sun

Is Neptune the closest to the Sun?

Does Neptune rain diamonds NASA?

Deep within Neptune and Uranus it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study however. Only a single space mission Voyager 2 has flown by to reveal some of their secrets so diamond rain has remained only a hypothesis.
