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

Detached

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.
