(120132) 2003 FY128 ( provisional designation 2003 FY128) is a trans-Neptunian object with a diameter of about 460 km. [4] It orbits the Sun at a distance of about 49.81 astronomical units. [3] It was discovered on 26 March 2003 by the NEAT program at the Palomar Observatory, California.
Classification
It is classified as a detached object by the Deep Ecliptic Survey (DES), since its orbit appears to be beyond the current control of Neptune. [2] Though, if Neptune migrated outward, there would have been a period when Neptune had a higher eccentricity.
