Mutual Orbits of Transneptunian Binaries

We aim to determine the mutual orbits for as many transneptunian binaries and multi-body systems as possible. In addition to providing dynamical masses, the statistical distributions of orbital properties offer clues about conditions in the protoplanetary nebula where these binaries formed, as well as about their subsequent evolution.

To this end, we are making use of the unique capabilities of the Hubble Space Telescope, Keck Telescopes, and Gemini Telescopes.
