(40314) 1999 KR16

(40314) 1999 KR16 is a trans-Neptunian object on an eccentric orbit in the outermost region of the Solar System, approximately 254 kilometers (158 miles) 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. The very reddish object has a rotation period of 11.7 hours. == Orbit and classification == The minor planet orbits the Sun at a distance between 34 and 65 AU once every 346 years (126,383 days; semi-major axis of 49.29 AU). Its orbit has an eccentricity of 0.31 and an inclination at an angle of 25° relative to the ecliptic. == Numbering and naming == This minor planet was numbered by the Minor Planet Center on 26 May 2002. As of 2025, it has not been named. == Physical characteristics == 1999 KR16 has two solutions for its rotation period of 6 and 12 hours, respectively, and an albedo of 0.20. == References == == External links == "TNOs are Cool": A Survey of the Transneptunian Region IV - Size/albedo characterization of 15 scattered disk and detached objects observed with Herschel Space Observatory-PACS List of Transneptunian Objects, Minor Planet Center Asteroid Lightcurve Database (LCDB), query form (info Archived 16 December 2017 at the Wayback Machine) (40314) 1999 KR16 at AstDyS-2, Asteroids—Dynamic Site Ephemeris · Observation prediction · Orbital info · Proper elements · Observational info (40314) 1999 KR16 at the JPL Small-Body Database
