C/1996 Q1 (Tabur) is a non-periodic comets that was expected to appear in the naked eye in but faded rapidly before doing so in 1996. It is the first of three comets discovered by Australian astronomer, Vello Tabur.
Orbit
Shortly after discovery, Brian G. Marsden computed the first parabolic orbit of the comet on 23 August 1996, which was roughly 73 degrees inclined to the ecliptic and an orbital period of approximately 18,500 years. A revised orbit was published about a week later, and Jost Jahn noted it has a strong resemblance to the orbit of C/1988 A1 (Liller), suggesting it might have fragmented from each other in a previous perihelion, despite the latter's shorter orbital period of 2,900 years. In the following years, more fragments of the same comet family were found, C/2015 F3 (SWAN) and C/2023 V5 (Leonard).
