(119951) 2002 KX14, also written as 2002 KX14, is a trans-Neptunian object (TNO) residing within the Kuiper belt. It was discovered on May 17, 2002 by Michael E. Brown and Chad Trujillo.
It has a semi-major axis, orbital period, and orbital eccentricity close to that of a plutino. The orbital periods of plutinos cluster around 247.2 years (1.5 x Neptune's orbital period). But (119951) 2002 KX14 is not classified as a plutino since is not in resonance with Neptune and it may have formed near its present quasi-circular orbit lying almost perfectly on the ecliptic. It may have remained dynamically cold and thus its orbit may not be a direct result of significant perturbations during Neptune's outward planetary migration. The Deep Ecliptic Survey (DES) currently shows it as a cubewano (classical) based on a 10 million year integration of the orbit.
It comes to opposition in late May at an apparent magnitude of 20.4. This makes it about 360 times fainter than Pluto.
