5370 Taranis (or 1986 RA) is an Amor asteroid discovered on September 2, 1986 by Alain Maury at Palomar.[1] It is one of very few asteroids located in the 2:1 mean-motion resonance with Jupiter.[5] When at aphelion of 5.4 AU,[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.[5]
It also is expected of being a dormant comet.[4] NEOWISE data suggests the object is 5.2−6.8 km in diameter.[4] On 10 September 2099 it will pass 0.1325 AU (19,820,000 km; 12,320,000 mi) from Earth.[1]
