Despina eclipses and transits Neptune (Despina brightened)
Despina, 148 kilometers across, is a tiny moon of Neptune located within its ring system and discovered by Voyager 2 in 1989 as the spacecraft approached for its flyby. The images were originally captured to study the colors of Neptune's clouds; the fact that Despina and its shadow were visible in the images was discovered by amateur image processor Ted Stryk in 2009.
