Rhadamanthus

Rhadamanthus is a Kuiper Belt object, a large rock that orbits round outside the orbit of Neptune. It has been categorised as a Trans-Neptunian object. It has an alternative name which is 38083 1999HX11. It was discovered on 17 April 1999 by Deep Ecliptic Survey. Its orbit takes 245.7870 years to travel round the Sun.

The absolute magnitude of the object is 6.7 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 albedo of the object is 0. The Albedo is the amount of radiation that is reflected back into space by the object.

The Aphelion of the object is 45.2831 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 33.1918 AU 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 9.9984 degrees. The Argument of Perihelion is 82.461. 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 80.7071, is the angular distance of the planet from the perihelion or aphelion. Ref:Dictionary.The Semi-Major Axis of the orbit is 39.2374 AU, which is the furthest point from the centre to the edge of an elliptical point.

The orbital inclination, the angle at which Rhadamanthus orbits in relation to the orbital plane is 12.718 degrees. The orbital eccentricity is 0.1541, it is the degree at which Rhadamanthus orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
