(120132) 2003 FY128, also written as (120132) 2003 FY128, is a trans-Neptunian object (TNO).


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.[1] Though, if Neptune migrated outward, there would have been a period when Neptune had a higher eccentricity.

It was discovered on March 26, 2003 by the NEAT program at the Palomar Observatory, California.
