(202421) 2005 UQ513 (

provisional designation 2005 UQ513) is a cubewano with an absolute magnitude of 3.97.[3] Its spectrum has a weak signature of absorption by water ice.[10][11] Like Quaoar, it has a very red spectrum,[12][13] which indicates that its surface probably contains many complex, processed organic molecules.[12] Its light curve shows variations of Δm=0.3 mag, but no period has been determined.[13]

Classification

2005 UQ513 has a perihelion of 37.3 AU.[3] The Minor Planet Center (MPC) classifies it as a cubewano[4] while the Deep Ecliptic Survey (DES) classifies it as ScatExt (scattered-extended).[5] Although dynamically it would have been a good candidate to be a member of the Haumea collisional family, given its red spectrum, it is not.[12][13]

Distance

As of December 2018, it is currently 48.0 AU from the Sun.[9] It will come to perihelion in 2123.[7]

It has been observed 194 times over 14

oppositions with precovery images back to 1990.[3]
