(196256) 2003 EH1 Asteroid

2003 EH1 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. It has an alternative name which is 2003 EH1.

2003 EH1 was discovered on 2003-03-06 by LONEOS.

The absolute magnitude of the object is 16.2 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 1. The Albedo is the amount of radiation that is reflected back into space by the object.

The Aphelion of the object is 5.058 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 1.190 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 283.0 degrees. The Argument of Perihelion is 171.4. 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 334.2, is the angular distance of the planet from the perihelion or aphelion. Ref:Dictionary.The Semi-Major Axis of the orbit is 3.124, which is the furthest point from the centre to the edge of an elliptical point.

The orbital inclination, the angle at which 2003 EH1 orbits in relation to the orbital plane is 70.8 degrees. The orbital eccentricity is 0.619, it is the degree at which 2003 EH1 orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
