35P/Herschel–Rigollet

35P/Herschel–Rigollet is a Halley-type comet with an orbital period of 155 years and an orbital inclination of 64 degrees. It was first discovered by Caroline Herschel on 21 December 1788. Given that the comet has a 155-year orbit involving asymmetric outgassing, and astrometric observations in 1939 were not as precise as modern observations, predictions for the next perihelion passage in 2092 vary by about a month.
