35P/Herschel–Rigollet is a periodic comet with an orbital period of 155 years. It fits the classical definition of a Halley-type comet with (20 years < period < 200 years). It was discovered by Caroline Herschel (Slough, United Kingdom) on 1788-12-21. Given that the comet takes 155 years to orbit the Sun, predictions for the next perihelion passage in 2092 vary by about a month.
