(145480) 2005 TB190, provisionally known as 2005 TB190, is a trans-Neptunian object with an absolute magnitude of 4.7. This qualifies it as a dwarf-planet candidate. (145480) 2005 TB190 is classified as scattered-extended by the Deep Ecliptic Survey since its orbit appears to be beyond significant gravitational interactions with Neptune's current orbit. Though if Neptune migrated outward, there would have been a period when Neptune had a higher eccentricity. The aphelion of 2005 TB190 lies beyond 106 AU.
