Its light-curve amplitude is estimated to be Δm=0.111 mag.〔Roland, S., Bruzzone, S., Nowajewski, P., Tancredi, G., Barrera, L., Martinez, M., Troncoso, P., & Vasquez, S. (2009). (Lightcurves of Icy “Dwarf Planets” (Plutoids) )〕 Its orbital eccentricity of 0.49 suggests that it was gravitationally scattered onto its eccentric orbit. It will come to perihelion in February 2046.〔 It has been observed 73 times over 11 oppositions with precovery images back to 1982.〔 ==Satellite== It has been reported that has a satellite, but a mass estimate has not been made.〔 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.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「(229762) 2007 UK126」の詳細全文を読む スポンサード リンク
