Beta Pictoris b is almost certainly a world of wonders, assuming it exists at all. Currently, we don't know much about it. What we do know is that beta Pictoris is surrounded by a disk
of dust and gas similar to the disk which our own solar system formed from. In many ways, beta Pictoris may be a solar system in the making.
