The existence of the gassy giant challenges long-standing theories that such a big planet -- about the size of Jupiter -- cannot be formed around a star so small. The star has a radius and mass about half that of the sun.

Planets are thought to form as gas and dust left over from massive galactic explosions, and swirling in disks around newborn stars, clump together to form bodies.
