2011 KW48 (original) (raw)
2011 KW48, temporarily designated VNH0004, is a trans-Neptunian object from the inner classical part of the Kuiper belt, located in the outermost region of the Solar System. It measures approximately 77 kilometers (48 mi) in diameter. The object was first observed on 29 May 2011, during the New Horizons KBO Search (266) conducted by astronomers using the Subaru Telescope at the Mauna Kea Observatory on Hawaii, United States. It was later observed by the New Horizons space probe from afar in January 2015.

It was later observed by the New Horizons space probe from afar in January 2015. (en) 2011 KW48, précédemment connu comme VNH0004, est le nom provisoire d'un objet transneptunien membre de la ceinture de Kuiper. La sonde New Horizons est passé, en janvier 2015, à environ 75 000 000 kilomètres de cet objet, ce qui est trop pour prendre de photos de bonne résolution, mais ceci aurait pu permettre la détection d'éventuels satellites. 2011 KW48 n'a été observé que 12 fois (8 fois par l'observatoire du Mauna Kea et 4 fois par l'observatoire de Las Campanas), entre le 29 mai et le 2 juillet 2011, soit un arc d'observation de 33,8 jours qui fait que les paramètres de son orbite sont très incertains. Johnstonsarchive estime son diamètre à environ 77 km. La Nasa n'a rien révélé au sujet de l'observation par la sonde (février 2018). (fr) 2011 KW48, também escrito como 2011 KW48, é um objeto transnetuniano que está localizado no Cinturão de Kuiper, uma região do Sistema Solar. Ele possui uma magnitude absoluta de 8,8 e tem um diâmetro estimado com cerca de 76 km. (pt) 2011 KW48 (ранее VNH0004) — транснептуновый объект из пояса Койпера. (ru) |
