Salacia
Discovered recently in 2004, Salacia is a candidate dwarf planet that resides in the Kuiper Belt. Not much is known about the candidate, as only large ground-based telescopes have gathered light from the candidate. There was no suggestion that Salacia has water ice on its surface, and therefore has the lowest reflectivity out of the large Kuiper Belt objects. More information is expected to be gathered about Salacia in the future.
