Oterma comet

Oterma is a periodic comet in our solar system. It has a centaur like orbit with a perihelion greater than Jupiter and a semi-major axis less than Neptune.

39P/Oterma underwent a temporary satellite capture (TSC) by Jupiter in 1936–1938. Such a Jupiter Family Comet is called a "quasi-Hilda comet" (QHC). However, this comet flew through the region near Jupiter over a rather short time, during which the comet did not complete a full revolution orbiting about the planet.

It was active from discovery in 1943, when it had a perihelion of 3.4 AU, until it was perturbed by Jupiter into an inactive centaur orbit in 1963, when it developed a perihelion of 5.4 AU. By 2195 it will have a perihelion distance of 6 AU
