APOD: Despina, Moon of Neptune

This image shows Neptune's tiny moon Despina in orbit. Despina was discovered in 1989 by Voyager 2 and is 148 kilometers across. Philosophy professor Ted Stryk discovered images showing Despina's shadow on Neptune's cloudy atmosphere in Voyager 2 data from 20 years earlier. This composite view of Despina shows four frames over the course of nine minutes. This moon was brightened so it is easier to see. Despina is the daughter of Neptune in Roman mythology. I was glad to come across this photograph of Neptune's moon because I did Neptune for my solar system project last quarter. I think that it's really interesting that the details in this photograph were found 20 years after it was first taken.
