Salacia was discovered on 2004-09-22 by H. G. Roe, M. E. Brown, K. M. Barkume. Its orbit takes 270.98 years to travel round the Sun.
The absolute magnitude of the object is 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 0.044. The Albedo is the amount of radiation that is reflected back into space by the object.
The Aphelion of the object is 46.620 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 37.497 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 279.9 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 311. 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 123.0, is the angular distance of the planet from the perihelion or aphelion. Ref:Dictionary.The Semi-Major Axis of the orbit is 42.058, which is the furthest point from the centre to the edge of an elliptical point.
The approximate diameter of Salacia is 850 km.
The orbital inclination, the angle at which Salacia orbits in relation to the orbital plane is 23.9 degrees. The orbital eccentricity is 0.108, it is the degree at which Salacia orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
Salacia is believed to be as big as Ceres which is the largest asteroid in the asteroid belt between Mars and Jupiter. It has a low albedo and therefore it is very dark compared to brighter objects such as Orcus. Planetary
Salacia is named after the goddess of sea water and the wife of Neptune, the Roman God of waters.
Unlike Pluto, we do not have any clear pictures of the object. There is no plans to visit the planet as yet, there are plans to visit Neptune so maybe if the technology is great enough and that the two objects come close, there might be a picture but the picture won't be clear.
Although it has not been classed officially as a Dwarf planet, it does have natural moon named Actaea in orbit round it. Actaea is named after the Nereid Aktaia, a sea nymph, a character in Greek mythology who was a daughter of Nereus and Doris.
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.
