Constraints on the Orbital Evolution of Triton Authors: Matija Cuk, Brett J. Gladman We present simulations of Triton's post-capture orbit that confirm the importance of Kozai-type oscillations in its orbital elements. In the context of the tidal orbital evolution model, these variation...

The planet Neptune will be occulted by the first quarter moon at 18:30 UT, 6th November, 2008, in the constellation Capricornus. Observers in the northern Britain will be well placed to see the occultation of Neptune. The next UK lunar occultation of Neptune will be at 23:55 UT, 25th June, 2016. Pl...

Despina, also known as Neptune V, is the third closest inner satellite of Neptune. It is named after Despoina, a nymph who was a daughter of Poseidon and Demeter. Despina was discovered in late July 1989 from the images taken by the Voyager 2 probe. It was given the temporary designation S/1989 N 3. The...
