92P/Sanguin, also calledSanguin's Comet orComet Sanguin, is aJupiter-family comet discovered on 15 October 1977, byJuan G. Sanguin atLeoncito Astronomical Complex.[3]
Initial estimates suggest that the comet completes a single rotation approximately once every 6 days,[7] however this was revised to just only 6.2 hours.[6]
The nucleus of the comet has a radius of about 1.19 km (0.74 mi) based on observations by theKeck Observatory, assuming ageometric albedo of 0.04.[5]
