One source stated that there would fewer than ten objects beyond Neptune which were this large. Hubble Telescope observation tends to confirm that Quaoar is spherical and has a circular orbit around the Sun of 42 AU [One AU (Astronomical Unit) equals the distance between Earth and the Sun. ] from the Sun. This contrasts with Pluto whose orbit varies from 29.5 to 48
