(40314) 1999 KR16 is a carbonaceous and eccentric trans-Neptunian object, approximately 250 kilometers in diameter. It was discovered on 16 May 1999, by French astronomer Audrey Delsanti and Oliver Hainaut at ESO's La Silla Observatory in northern Chile.[9]

Orbit and classification[edit]

The C-type minor planet orbits the Sun at a distance of 34.0–64.5 AU once every 345 years and 6 months (126,197 days). Its orbit has an eccentricity of 0.31 and an inclination of 25° with respect to the ecliptic.[1]

Physical characteristics[edit]

1999 KR16 has two solutions of its rotation period of 6 and 12 hours, respectively,[4][5] and an albedo of 0.20.[3]

Numbering and naming[edit]

This minor planet was numbered by the Minor Planet Center on 26 May 2002.[10] As of 2018, it has not been named.[9]
