(543354) 2014 AN55 provisional designation 2014 AN55 trans-Neptunian object in the scattered disc , located in the outermost region of the Solar System , that measures approximately 600 kilometres (370 mi ) in diameter. It was discovered on 25 January 2014, by astronomers with the Pan-STARRS survey at Haleakala Observatory on the island of Maui, Hawaii, in the United States.[1]
Orbit and classification [ edit ]
2014 AN55 belongs to the gravitationally perturbed population of scattered disc objects ,[3] Neptune 's orbit at 30 AU
It orbits the Sun at a distance of 34.3–77.6 AU semi-major axis of 55.92 AU ). Its orbit has an eccentricity of 0.39 and an inclination of 9° with respect to the ecliptic .[2] observation arc begins with its first observation taken by the Sloan Digital Sky Survey on 12 March 2005.[1]
Numbering and naming [ edit ]
This minor planet was numbered by the Minor Planet Center on 5 February 2020 (M.P.C. 121072name .[8]
Physical characteristics [ edit ]
Diameter and albedo [ edit ]
Using an absolute magnitude of 4.3 from the Asteroids—Dynamic Site,[7] albedo in the range of 0.05 to 0.25, the object's mean diameter may be as low as 370, or as high as 820 kilometers.[6] Johnstons' s Archive assumes a similar albedo of 0.9 and calculates a diameter of 671 kilometers using an absolute magnitude of 4.1.[3] [6]
