re: IAU Planet Definition
Found about the IAU's definition for planets around other stars:
The minimum mass/size required for an extrasolar object to be
considered a planet should be the same as that used in our Solar System..
Considering we know about the presence of 200 celestial bodies around other stars, and that they are most of the time many times Jupiter's mass, this is about all we know about them. Only one was pictured (if it indeed is one).
It's too early to officially call them one way or another.
