mp|(119951) 2002 KX|14, 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. It may have remained dynamically cold and thus its orbit may not be a direct result of perturbations during Neptune's outward planetary migration.

It comes to opposition in late May at an apparent magnitude of 20.4. This makes it about 360 times fainter than Pluto. [(5th root of 100)^(20.4- [http://ssd.jpl.nasa.gov/horizons.cgi?find_body=1&body_group=sb&sstr=Pluto 14] =363)]
