**** (provisional designation ****) is a classical Kuiper belt object with an absolute magnitude of 3.91, and estimated to be around in diameter. Like Quaoar, it has a very red spectrum, which indicates that its surface probably contains many complex, processed organic molecules. Its light curve shows variations of Δm=0.3 mag, but no period has been determined.
Classification
has a perihelion of 37.3 AU. The Minor Planet Center (MPC) classifies it as a classical Kuiper belt object (cubewano) while the Deep Ecliptic Survey (DES) classifies it as ScatExt (scattered-extended). Although dynamically it would have been a good candidate to be a member of the Haumea collisional family, given its red spectrum, it is probably not.
Distance
As of December 2018, it is currently 48.0 AU from the Sun. It will come to perihelion in 2123.
It has been observed 194 times over 14 oppositions with precovery images back to 1990.
