(229762) 2007 UK126, also written as (229762) 2007 UK126, is a scattered disc object (SDO) with a bright absolute magnitude of 3.7.[5] This makes it probably a dwarf planet. As of August 2011[update], Mike Brown lists it as highly likely a dwarf planet.[8] Its light-curve amplitude is estimated to be Δm=0.111 mag.[9]
Its orbital eccentricity of 0.49 suggests that it was gravitationally scattered onto its eccentric orbit. It will come to perihelion in February 2046.[6]
It has been observed 73 times over 11 oppositions with precovery images back to 1982.[6]
Satellite
It has been reported that (229762) 2007 UK126 has a satellite, but a mass estimate has not been made.[5] The magnitude difference between the primary and the satellite is 3.79 mag. The satellite has a tentative diameter of 139 km, a semi-major axis of 3600 km, and an orbital period of 3.7 d.[4]
