2006 SQ372 is a small trans-Neptunian object discovered throught the Sloan Digital Sky Survey by Andrew Becker, Nathan Kaib and coworkers.^[2]^[3]

It has a strongly eccentric orbit, intersecting that of Neptune at perihelion but bringing it 1600 AU from the Sun at aphelion. Its orbit takes about 22000 years to complete. In this respect it is similar to 90377 Sedna or 2000 CR₁₀₅. However, having a diameter between 50 and 100 km, it is much smaller and it could possibly be a comet. Their discoverers hypothesize that the object could come from the inner Oort cloud.
