The third is at the same distance as 2003 EL61, and probably modestly larger. It was last designated as 2005FY9 if I remember correctly. It has kind of fallen through the cracks, between the Spanish amateur scooping 2003 EL61 and 2003 UB313 being a really intriguing object.

What sort of telescope does he have?
Three new Prison Colonies.
