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, which means that for every seven orbits of Neptune around the Sun, it makes four orbits. Its diameter is about 420 kilometres (260 mi). It is expected to be a dwarf planet if its size estimate is correct.
It is currently at 47.3 AU from the Sun.
