    (469306) 1999 CD158, also written as 1999 CD158, is a resonant trans-Neptunian object (TNO) that resides in the Kuiper belt. It has an orbital resonance of 4:7 with Neptune,[1] which means that for every seven orbits of Neptune around the Sun, it makes four orbits. Its diameter is about 420 kilometres (260 mi).[1] It is expected to be a dwarf planet if its size estimate is correct.[5]

    It is currently at 47.3 AU from the Sun.[6]
