Pan 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 is also know by other designations, SXVIII, S/1981 S13. Its mass is estimated/calculated at being 4,945,605,829,220,740 kg. Its density has been calculated at being 0.42. Its volume is 11742.
It was discovered in the year 1990 by Mark R. Showalter, Voyager 2. A close approach will occur on 2008 Feb 19 when it will get to within 0.0408 A.U. Its orbit takes 0.575 years to travel round the Sun.
The absolute magnitude of the object is 17.1 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 2.288 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 0.596 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 311.8 degrees. The Argument of Perihelion is 291.8. 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 134.1, is the angular distance of the planet from the perihelion or aphelion. Ref:Dictionary.The Escape Velocity of the object is 25 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 133.583, which is the furthest point from the centre to the edge of an elliptical point.
The equatorial circumference of Pan is 88.6 km. The surface area of Pan is 2,498.32. The surface gravity of the said item is 0.002. The Mean orbit velocity, that is the speed at which it orbits is 60819.40 km/h. The is the average distance in km of the object is from its parent 133580.00.
The orbital inclination, the angle at which Pan orbits in relation to the orbital plane is 0 degrees. The orbital eccentricity is 0, it is the degree at which Pan orbits close to a circular (0) orbit as opposed to an elliptical (1) 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.
