Moon of the Day - Triton
Today's moon is Triton, the largest moon of Neptune.
Triton (not to be confused with Titan) is another favorite of mine. It has a retrograde orbit which, in addition to its composition, has led astronomers to believe that it was once a Kuiper Belt object that was captured by Neptune. As we mentioned earlier, it is one of the few moons that has been observed to be geologically active, with geysers spewing liquid nitrogen.
Triton was discovered in October 1846, only 17 days after the discovery of Neptune.
