Comet Schaumasse is a periodic comet discovered by Alexandre Schaumasse (Nice, France) on 1 December 1911 as 12th magnitude.[1] It next comes to perihelion on 8 January 2026 and should brighten to about magnitude 9.[2]
Observations
By the end of 1912 it was recognised as a short period comet estimated to return in 7.1 years, later recalculated as 8 years.[1] The 1919 return was recovered by Gaston Fayet (Paris, France) as magnitude 10.5.[1]
The 1927 approach was magnitude 12, but the comet was missed on the 1935 approach.[1] In 1937 it passed close to Jupiter which increased its orbital period slightly.[1] During the 1951-1952 apparition, the comet was brighter than expected, reaching a magnitude of about 6 in February.[1]
The comet was missed in 1968 and 1976.[1] It was speculated that the increase in brightness in 1952 indicated a problem that led to it vanishing. The comet during the 1984 apparition was recovered by James B. Gibson (Palomar Observatory, California, USA).[3] Also in 1984 was reported that Elizabeth Roemer (Steward Observatory, Arizona, USA) had found a comet on a photograph from 27 December 1976.[1] Orbital calculations by Brian G. Marsden, confirmed the 1976 image featured Comet Schaumasse.[1][3]
The comet was not observed during the 2009 unfavorable apparition since the perihelion passage occurred when the comet was on the far side of the Sun. It passed within Шаблон:Convert of the dwarf planet Ceres on 22 March 2010.[4] During the 2017 apparition the comet reached a magnitude of 10.[5] It was last observed on 19 June 2018 when it was 2.7 AU from the Sun.[6]

Around 3 October 2100 it should pass about Шаблон:Convert from Mars.[7]
The comet nucleus is estimated to be 2.6 kilometers in diameter.[4]
