10199 Chariklo Asteroid

Chariklo is an asteroid, a large rock that orbits the Sun mainly between the orbits of Mars and Jupiter. They tend to be an irregular shaped but Ceres asteroid is known to be spherical in shape but because it doesn't clear its path round the Sun, it is only a dwarf planet.

Chariklo was discovered on 15th Feb 1997 by Spacewatch. Its orbit takes 62.93 years to travel round the Sun.

The absolute magnitude of the object is 6.569 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 0.045. The Albedo is the amount of radiation that is reflected back into space by the object.

The Perihelion of the object is 13.099 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 300.42 degrees. The Argument of Perihelion is 242.9. 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 77.670, is the angular distance of the planet from the perihelion or aphelion. Ref:Dictionary.The Semi-Major Axis of the orbit is 15.822, which is the furthest point from the centre to the edge of an elliptical point.

The approximate diameter of Chariklo is 252 km.

The orbital inclination, the angle at which Chariklo orbits in relation to the orbital plane is 23.382 degrees. The orbital eccentricity is 0.1721, it is the degree at which Chariklo orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.

One of the most interesting items about this asteroid is that it has a ring around it. When people think of a ring, they probably think of science fiction or the rings of Saturn and not an asteroid. The Wiki page reveals that there are two sizes for the asteroid and either can be right. The site only deals with absolutes which is why you will find some sites will have multiple values for figures.
