38P/Stephan–Oterma (also known as Comet Stephan–Oterma) is a periodic comet with an orbital period of 38 years. It fits the classical definition of a Halley-type comet with (20 years < period < 200 years).[1] It was discovered in January 1867, by Jérôme Eugène Coggia at Marseilles Observatory, France.[1]
38P/Stephan–Oterma last came to perihelion on November 10, 2018.[2][3] It was recovered by Pan-STARRS on June 24, 2017 while 5.3 AU from the Sun.[2] The next perihelion passage is August 28, 2056.[2]
Orbit
It has perihelion near the orbit of Mars and has aphelion near the orbit of Uranus. Acting like a centaur-hybrid, between the years 1982 and 2067, this object will make close approaches to the giant planets Jupiter, Saturn, and Uranus.[4] If this object did not have a coma and (for some definitions) had a perihelion beyond Jupiter's (5 AU), it would be considered a centaur.
