A Halley-type comet,a lso known as an intermediate-period comet, is a subcategory of short-period comets with a period of 20 to 200 years and an orbit of high inclination. Halley-type comets, named after their celebrated prototype (see Halley's Comet), are believed to have come from the Oort Cloud. This makes them distinct, in origin and orbital characteristics, from Jupiter-type comets.
