C/2023 V5 (Leonard) was discovered on 6 November 2023 by the Catalina Sky Survey. It came to perihelion on 13 December 2023 at 0.849 AU (127.0 million km), from the Sun.[3][4] It is probably a Liller family comet, together with C/1988 A1 (Liller), C/1996 Q1 (Tabur), C/2015 F3 (SWAN), and C/2019 Y1 (ATLAS).[5][6]
JPL Horizons shows both an inbound and outbound eccentricity greater than 1.[2]
Comet C/2023 V5 is probably a secondary fragment of one of the primary fragments of C/1988 A1 (Liller).[6]
