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 kg. 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.

Quaoar was discovered on 2002-06-04 by C. A. Trujillo, M. E. Brown. Its orbit takes 104449.918 d (285.97 a) years to travel round the Sun.

The absolute magnitude of the object is 2.4 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 45.420 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 41.964 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 188.8 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 146.4. 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 300.7, is the angular distance of the planet from the perihelion or aphelion. Ref:Dictionary.The Escape Velocity of the object is 0.523-0.712 Km/s km/h. The Escape Velocity is the speed an object needs to be travelling in order to break free from the objects gravity. The larger an object is, the more velocity (speed) is needed to break free from the object.The Semi-Major Axis of the orbit is 43.692, which is the furthest point from the centre to the edge of an elliptical point.

The mean temperature of the object is ~43K.

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 8 degrees. The orbital eccentricity is 0.040, it is the degree at which Quaoar orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.

Path of Quaoar Orbit

If the white lines are above, then the path of the object is under the ecliptic. If the white lines are below, the path is above the ecliptic. This refers to the Inclination of the object. The image was created using N.A.S.A. Solar System Dynamics.
