- 2012 إتش إتش 2 (ويعرف أيضًا باسم (432949) 2012 إتش إتش 2 وفق تسمية الكوكب الصغير) (بالإنجليزية: 2012 HH2) هو كويكب ضمن حزام الكويكبات؛ وترتيبه 432949 من حيث الاكتشاف.اكتُشف هذا الجُرم الفلكي بواسطة Tomáš Vorobjov في 19 أبريل 2012. (ar)
- (432949) 2012 HH2 is a resonant trans-Neptunian object, approximately 255 kilometers (160 miles) in diameter, located in the outermost region of the Solar System. It was discovered by Slovak astronomer Tomáš Vorobjov from images taken on the night of 19 April 2012, at the Astronomical Research Institute (H21) in Illinois, United States. This minor planet was numbered (432949) by the Minor Planet Center on 4 April 2015 (M.P.C. 93615). As of 2021, it has not been named. 2012 HH2 is a resonant trans-Neptunian object in an uncommon 4:5 resonance with Neptune (DES: 5:4E). It orbits the Sun at a distance of 29.2–40.4 AU once every 205 years and 4 months (75,008 days; semi-major axis of 34.81 AU). Its orbit has an eccentricity of 0.16 and an inclination of 29° with respect to the ecliptic. It is currently 29.8 AU from the Sun. As of 2021, no rotational lightcurve of 2012 HH2 has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown. Johnston's Archive estimates a mean-diameter of 255 kilometers (160 miles), using a standard magnitude-to-diameter conversion with an assumed albedo of 0.09. Astronomer Mike Brown gives a nearly identical estimates of 253 kilometers (160 miles) for the object's diameter with an albedo of 0.08 and an absolute magnitude of 6.3. (en)
- (432949) 2012 HH2 est un objet transneptunien (OTN) ayant une faible probabilité d'être une planète naine. Il fut découvert par Tomáš Vorobjov sur des images prises la nuit du 19 avril 2012 à l'Illinois University Observatory de Charleston (H20). L'objet a été observé 67 fois en deux oppositions. Il se trouve actuellement[Quand ?] à 29,8 unités astronomiques du Soleil. (fr)
- 2012 HH2 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 0.166, sementara magnitudo mutlaknya adalah 6.3. (in)
- (432949) 2012 HH2, também escrito como (432949) 2012 HH2, é um objeto transnetuniano que está localizado no cinturão de Kuiper, uma região do Sistema Solar. Este corpo celeste está em uma ressonância orbital de 4:5 com o planeta Netuno. Ele possui uma magnitude absoluta de 6,4 e tem um diâmetro com cerca de 231 km. O astrônomo Mike Brown lista este objeto em sua página na internet como um candidato a possível planeta anão. (pt)
