1998 S1 P/LINEAR-Mueller was discovered by Jean Mueller on 1998 October 17 on a 30-min exposure taken on Oct 14 with the 1.2-m Oschin Schmidt telescope at Palomar by K. Rykoski and Mueller in the course of Palomar Outer Solar System Ecliptic Survey. The comet was confirmed on Oct 17 and Gareth Williams later identified it with minor planets observed by LINEAR on Sept 26 and 27 and LONEOS on Sept 17. The comet is of short period and had a close approach to Jupiter in 1992. Rob McNaught recovered the comet (designated 2007 J7) with the 0.5-m Uppsala Schmidt at Siding Spring on 2007 May 13 and Jim Scotti independently recovered it with the Spacewatch 1.8-m f/2.7 reflector at Kitt Peak on June 26.
