(202421) 2005 UQ513, also written as 2005 UQ513, is a cubewano with an absolute magnitude of 3.4.[2] Mike Brown's website lists it as a highly likely dwarf planet.[8] (202421) 2005 UQ513's spectrum has a weak signature of absorption by water ice.[9] Like Quaoar,[10] it has a very[10] red spectrum,[11][12] which indicates that its surface probably contains a lot of complex, processed organic molecules.[11] Its light curve shows variations of Δm=0.3 mag, but no period has been determined.[12]

Classification

(202421) 2005 UQ513 has a perihelion of 37.3 AU.[2] The Minor Planet Center (MPC) classifies it as a cubewano[3] while the Deep Ecliptic Survey (DES) classifies it as ScatExt (scattered-extended).[4] 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.[11][12]

Distance

It is currently 48.8 AU from the Sun.[7] It will come to perihelion around 2123.[2]

It has been observed 194 times over 14 oppositions with precovery images back to 1990.[2]
