Discovery
Reinmuth was discovered during a survey of small Solar System bodies with the 40 cm Bruce telescope at the LSW-Heidelberg Observatory in Heidelberg, Germany. The absolute magnitude of the comet was estimated by Karl Reinmuth to be 13, two orders of magnitude smaller than the current estimate.[2]
This comet was found to be a
Relationship with Jupiter
Reinmuth makes many close approaches to Jupiter. These close approaches gradually change its orbit. For example, on July 16, 2003, comet Reinmuth came within 0.74 AU of Jupiter.[1] This increased its perihelion from 1.89 to 2.11 AU and its orbital period from 6.63 to 7.07 years.[2] On February 11, 2039, Reinmuth will come within 0.52 AU of Jupiter, which will raise its perihelion to 2.44 AU and its orbital period to 7.78 years.[2] On July 21, 2063 and March 1, 2146, Reinmuth will come 0.43 AU and 0.51 AU, respectively.[1] Close approaches like these could raise Reinmuth's perihelion until it ceases to become a comet.
