Quaoar

Quaoar is a Kuiper Belt object, a large rock that orbits round outside the orbit of Neptune. It has been categorised as a Kuiper Belt object. Its mass is estimated/calculated at being 1.0-2.6x10^21kg. Its name is derived from Native American Tongva Creation God. It has an alternative name which is 2002 LM60. Its density has been calculated at being 2.0 g/cm2. It was discovered on 4 June 2002 by M. Brown, C. Trujillo. Its orbit takes 104449.918 d (285.97 a) years to travel round the Sun.

The absolute magnitude of the object is 2.6 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 0.1. The Albedo is the amount of radiation that is reflected back into space by the object.

The Aphelion of the object is 44.896 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 6270.316 GM (41.914 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 188.791 degrees. The Argument of Perihelion is 154.85. 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 273.737, is the angular distance of the planet from the perihelion or aphelion. Ref:Dictionary.The Semi-Major Axis of the orbit is 6493.296 GM (43.405 AU), which is the furthest point from the centre to the edge of an elliptical point.

The mean temperature of the object is ~43K.

The mass of the object is calculated at being 1.0-2.6x10^21kg. The surface gravity of the said item is 0.276-0.376 m/s2.

The orbital inclination, the angle at which Quaoar orbits in relation to the orbital plane is 7.983 degrees. The orbital eccentricity is 0.034, it is the degree at which Quaoar orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
