Comet ATLAS, formal designation C/2022 R2, is a non-periodic comet with a very small minimum orbit intersection distance with Earth, only about 0.045 AU (6.7 million km).[3] This has led to an assessment that it may generate a potential meteor shower with a radiant in the general direction from the constellation Lepus by 22–24 November.[4]
On 3 October 2022, observations from the Zwicky Transient Facility showed that the comet had experienced a strong outburst, temporarily increasing its apparent magnitude to 14.24, then rapidly faded away afterwards, indicating that the comet had disintegrated.[5]
