Citizen "Ice Hunters" help find a Neptune Trojan target for New Horizons

2011 HM102 is an L5 Neptune Trojan, trailing Neptune by approximately 60 degrees. This object was discovered in the search for a New Horizons post-Pluto encounter object in the Kuiper Belt.

Pluto is now known to have at least five moons (Charon, Nix, Hydra, P4, and the newly discovered P5), and its burgeoning population might pose a risk to New Horizons during its flyby, three years from now.

A newly published paper shows trans-Neptunian object Salacia to be unexpectedly large; it's somewhere around the tenth largest known thing beyond Neptune. It has a companion one-third its size, making it appear similar to Orcus and Vanth.

Where are the big Kuiper belt objects?

Earlier today I wrote a post about how to calculate the position of a body in space from its orbital elements. I'm trying to get a big-picture view of what's going on in trans-Neptunian space.

On May 5 and 6, I had a run on the WIYN (Wisconsin-Indiana-Yale-NOAO) telescope, a 3.5 m telescope, the second largest telescope on Kitt Peak in Arizona.
