(40314) 1999 KR16, also written as (40314) 1999 KR16, is a carbonaceous and eccentric minor planet, classified as trans-Neptunian object (TNO), about 250 kilometers in diameter. It was discovered by French female astronomer Audrey Delsanti and Oliver Hainaut at ESO's La Silla Observatory, Chile, on 16 May 1999.[6]
The C-type minor planet orbits the Sun at a distance of 34–64 AU once every 342 years and 1 month (124,953 days). Its orbit shows a high eccentricity of 0.31 and is notably tilted by 25 degrees to the plane of the ecliptic. It has a rotation period of 6 to 12 hours[4][5] and an albedo of 0.20.[2]
