(40314) 1999 KR16 is a carbonaceous and eccentric trans-Neptunian object (TNO), 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]

Naming[edit]

As of 2017, this minor planet remains unnamed.[9]
