The object is merely in the direction of the Alpha Centauri system. If it's in that system, given its brightness, it would probably be a red dwarf, and we would have found it years ago. Assuming it's not just an imaging glitch, it must be either a larger object farther away (very unlikely given its motion), or a smaller and closer body. More observations would be needed to distinguish among the possibilities.
