    (202421) 2005 UQ513 (provisional designation 2005 UQ513) is a classical Kuiper belt object 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 Classical Kuiper belt object (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 probably 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]
