Description

Taranis was discovered on 2 September 1986, by French astronomer Alain Maury at the Palomar Observatory in California, United States.[2] It is one of very few asteroids located in the 2:1 mean-motion resonance with Jupiter.[8] 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.[8]

Taranis also is expected of being a dormant comet.[5] On 10 September 2099 it will pass 0.1325 AU (19,820,000 km; 12,320,000 mi) from Earth.[1]

This minor planet was named after the Gaulish god of thunder Taranis from Celtic mythology. The official naming citation was published by the Minor Planet Center on 1 September 1993 (M.P.C. 22509).[9]

[ru] (5370) Таранис

(5370) Таранис (лат. Taranis) — околоземный астероид из группы Амура (III), который примечателен прежде всего тем, что является одним из немногих амуров, так далеко уходящих от Солнца, что пересекает не только орбиту Марса, но и орбиту Юпитера, находясь при этом ещё и в орбитальном резонансе 2:1 с этой планетой[3]. Он был открыт 2 сентября 1986 года французским астрономом Аленом Мори в Паломарской обсерватории и назван в честь Тараниса, бога грома в кельтской мифологии[4].
