2015 KG 163 is a planetoid that was discovered on May 24, 2015 at Mauna Kea and belongs to the group of the Kuiper belt planetoid. The asteroid orbit the sun in a highly eccentric orbit for almost 24,000 years . The orbital eccentricity of its orbit is 0.95, with this 14.00 ° inclined to the ecliptic .

Orbit parameters of highly extreme trans-Neptunian objects with perihelias greater than 30 AU and major semi-axes greater than 250 AU Note: Data taken from MPC, the information is best fits and therefore subject to great uncertainties
