C/2023 V5 (Leonard) was discovered on 6 November 2023 by the Catalina Sky Survey. It came to perihelion on 13 December 2023 at {{Convert|0.849|AU|e6km|abbr=unit|lk=on}}, from the Sun. 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).
Orbit
JPL Horizons shows both an inbound and outbound eccentricity greater than 1.
Comet C/2023 V5 is probably a secondary fragment of one of the primary fragments of C/1988 A1 (Liller).
