Quaoar's diameter is roughly half that of Pluto and is slightly smaller than Pluto's moon Charon. [29] At the time of its discovery in 2002, Quaoar was the largest object found in the Solar System since the discovery of Pluto. [29] Quaoar was also the first trans-Neptunian object to be measured directly from Hubble Space Telescope images. [19]
Chingichngish (also spelled Chengiichngech, [1] Chinigchinix, Chinigchinich, Changitchnish, etc.), also known as Quaoar (also Qua-o-ar, Kwawar, etc.) and by other names including Ouiamot, Tobet and Saor, [2] is an important mythological figure of the Mission Indians of coastal Southern California, a group of Takic-speaking peoples, today divided into the Payómkawichum (Luiseño), Tongva ...
Weywot (formal designation (50000) Quaoar I; provisional designation S/2006 (50000) 1) is a natural satellite or moon of the trans-Neptunian dwarf planet Quaoar. It was discovered by Michael Brown and Terry-Ann Suer using images taken by the Hubble Space Telescope on 14 February 2006. It is named after the Tongva sky god and son of Quaoar ...
On the other hand, the surfaces of Sedna, Gonggong and Quaoar have low abundances of CO and CO 2, similar to Pluto, Eris and Makemake but in contrast to smaller bodies. This suggests that the threshold for dwarf planethood in the trans-Neptunian region is a diameter of ~1000 km (thus including only Pluto, Eris, Haumea, Makemake, Gonggong ...
The IAU itself has called Quaoar a dwarf planet in a 2022–2023 annual report. [ 65 ] More bodies have been proposed, such as Salacia and (307261) 2002 MS 4 by Brown; Varuna and Ixion by Tancredi et al., and (532037) 2013 FY 27 by Sheppard et al. [ 66 ] Most of the larger bodies have moons, which enables a determination of their mass and thus ...
Quaoar, a classical KBO discovered in 2002, is over 1,200 km across. Makemake and Haumea , both announced on 29 July 2005, are larger still. Other objects, such as 28978 Ixion (discovered in 2001) and 20000 Varuna (discovered in 2000), measure roughly 600–700 km (373–435 mi) across.
