(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 the semi-major axis typical of a plutino. But it is rarely classified as such since it may have formed near its present quasi-circular orbit lying almost perfectly on the ecliptic. Its orbit may not be a direct result of Neptune's outward planetary migration.
