C/2019 Y1 (ATLAS)

C/2019 Y1 (ATLAS) is a comet with a near-parabolic orbit discovered by the ATLAS survey on 16 December 2019. It passed perihelion on 15 March 2020 at 0.84 AU from the Sun. Its orbit is very similar to C/1988 A1 (Liller), C/1996 Q1 (Tabur), C/2015 F3 (SWAN) and C/2023 V5 (Leonard), suggesting they may be fragments of a larger ancient comet.

Observations
The comet passed close to Earth in early May 2020. It was visible in the northern hemisphere sky in the spring of 2020.
