373P/Rinner is a periodic comet with a 7.42-year orbit around the Sun. It is the first comet discovered by French astronomer, Claudine Rinner, and the first comet discovery from France since C/1997 J2 (Meunier–Dupouy).
== Observational history == The comet was first discovered on CCD images taken from the Oukaïmeden Observatory in 28 November 2011. Claudine Rinner noted a faint tail about an arcminute in length, nearly an 18th-magnitude object in the constellation Canis Minor. Additional observations across the globe in the following days would later confirm the existence of Rinner's comet, which was subsequently designated as P/2011 W2. Gareth V. Williams provided the comet's preliminary orbital elements on the Minor Planet Center's site, which indicated it is in a roughly 10-year periodic orbit around the Sun.
