5370 Taranis, provisional designation1986 RA, is anasteroid and suspecteddormant comet on an eccentric orbit, classified asnear-Earth object of theAmor group, approximately 5 kilometers in diameter.
Taranis was discovered on 2 September 1986, by French astronomerAlain Maury at thePalomar Observatory in California, United States.[2] It is one of very few asteroids located in the 2:1mean-motion resonance withJupiter.[8] When ataphelion of 5.4AU,[1] the object is roughly the same distance from the Sun as Jupiter is when Jupiter is at aphelion. The unstable resonance with Jupiter is expected to last roughly 7.3 million years.[8]
Taranis also is expected of being adormant comet.[5] On 10 September 2099 it will pass 0.1325 AU (19,820,000 km; 12,320,000 mi) from Earth.[1]
Thisminor planet was named after the Gaulish god of thunderTaranis fromCeltic mythology. The official naming citation was published by theMinor Planet Center on 1 September 1993 (M.P.C. 22509).[9]
