(248590) 2006 CS

(Redirected from 2006 CS)

(248590) 2006 CS is an asteroid, classified as a near-Earth object of the Apollo group and probably a dormant Jupiter family comet.[2] It was discovered on 1 February 2006 by the Siding Spring Survey.[1] The object has been suggested to be the progenitor body of the β Tucanids or δ Mensids meteor showers, being, according to Diego Janches et al, a better candidate than the previously suggested comet C/1976 D1 (Bradfield). They also suggest the two showers are actually one and the same.[3] The meteor shower produced outbursts in 2020 and 2024.[2]
