KELT-11b

KELT-11b  is a very strange world.  It's a gas giant, larger than Jupiter, but with the density of styrofoam.  That density is partly due to an atmosphere that's 1716 miles deep.

It's also a world not long for the universe.  Within a hundred million years, ir will be absorbed by its red giant parent star.
