The orbits of multiple objects in the Haumea family. 2003 SQ317 is not shown in the diagram, though its orbit is similar to that of other objects in the Haumea family.
2003 SQ317 is a classical Kuiper belt object (cubewano) belonging to the hot population. Its size estimated to lie between 150 and 450 km based on a range of plausible albedos. The object has a large light curve amplitude of about 0.85, which indicates that it has an extremely elongated shape or is a contact binary.[8] In the former case the density of 2003 SQ317 is estimated at 0.86 g/cm3 and its axis ratios at 0.55 and 0.41. If 2003 SQ317 is a contact binary, which is actually more likely, the density is estimated at 2.67 g/cm3. In the latter case, the components are also thought to be unequal in size with the mass ratio of about 0.3 and axis ratios of about 0.8 and 0.5, respectively, for the primary and secondary components.[6]
