(59358) 1999 CL₁₅₈, also written as (59358) 1999 CL158, is a trans-Neptunian object that resides in the Kuiper belt. It was discovered on February 11, 1999, by Jane X. Luu, Chad Trujillo, and David C. Jewitt at the Mauna Kea Observatory, Hawaii.

Unstable

Simulations by the Deep Ecliptic Survey (DES) show this object may be removed (ejected) from the Solar System over the next 10 million years.^[1]
