Arawn is a Kuiper Belt object, a large rock that orbits round outside the orbit of Neptune. It has been categorised as a object. It has an alternative name which is 1994 JR1.

Arawn was discovered on 1994-05-12 by M. J. Irwin, A. Zytkow.

The absolute magnitude of the object is 7.7 which is the brightness of the object. A higher absolute magnitude means that the object is faint whereas a very low number means it is very bright.

The Aphelion of the object is 44.592 A.U. which is the point in the orbit that is furthest from the object that it is orbit. At this point, it will then return back to the orbit target. The Perihelion of the object is 34.788 A.U. which is the point in the orbit that is closest to the object that it is orbit around. The Longitude of Ascending Node of the object is 144.8 degrees. It is the angle between the Reference Direction and the Ascending Node. It is normally represented by the greek letter Ω. The ascending node is the point in which the object passes north. The descending node is the southern.The Argument of Perihelion is 103.9. It is the angle along the orbit of a planet or other Solar System object as measured from the ascending node (analogous to right ascension and longitude) Ref:Hawaii.

The mean anomoly is 32.0, is the angular distance of the planet from the perihelion or aphelion. Ref:Dictionary.The Semi-Major Axis of the orbit is 39.690, which is the furthest point from the centre to the edge of an elliptical point.

The orbital inclination, the angle at which Arawn orbits in relation to the orbital plane is 3.8 degrees. The orbital eccentricity is 0.124, it is the degree at which Arawn orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
