(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]
