2011 JY31 (original) (raw)
2011 JY31 is a binary trans-Neptunian object from the Kuiper belt, located in the outermost region of the Solar System. It was discovered on 4 May 2011, by a team of astronomers using one of the Magellan Telescopes in Chile during the New Horizons KBO Search for a potential flyby target for the New Horizons spacecraft. Distant observations by New Horizons from September 2018 revealed its binary nature, showing two 50 km (31 mi)-wide components in a tight, mutual orbit 200 km (120 mi) apart. The discovery adds support to streaming instability as the dominant mechanism in the formation of tight and contact binary planetesimals such as 486958 Arrokoth, which appear to be prevalent in the cold classical Kuiper belt population.

(en) 2011 JY31 adalah sebuah objek trans-Neptunus. Seperti objek trans-Neptunus pada umumnya, benda ini mengorbit Matahari dari jarak yang lebih jauh dari planet Neptunus. Eksentrisitas orbit objek ini tercatat sebesar 0.055, sementara magnitudo mutlaknya adalah 8.8. (in) 2011 JY31, também escrito como 2011 JY31, é um objeto transnetuniano que está localizado no Cinturão de Kuiper, uma região do Sistema Solar. Este corpo celeste é classificado como um cubewano. Ele possui uma magnitude absoluta de 8,8 e tem um diâmetro estimado com cerca de 76 km. (pt) |
