MakeMake

MakeMake 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 2005 FY9.

MakeMake was discovered on 2005-03-31 by M. E. Brown, C. A. Trujillo, D. L. Rabinowitz. Its takes 22.48 Hours to do a full rotation period.

The absolute magnitude of the object is -0.2 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 0.04. The Albedo is the amount of radiation that is reflected back into space by the object.

The Aphelion of the object is 52.760 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 38.357 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 79.6 degrees. The Argument of Perihelion is 295.1. 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 164.0, is the angular distance of the planet from the perihelion or aphelion. Ref:Dictionary.The Semi-Major Axis of the orbit is 45.558, which is the furthest point from the centre to the edge of an elliptical point.

The orbital inclination, the angle at which MakeMake orbits in relation to the orbital plane is 29 degrees. The orbital eccentricity is 0.158, it is the degree at which MakeMake orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.

Path of MakeMake 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.
