Where's the Dividing Line Between A Star and A Planet? Ask the JWST.

JWST directly imaged 29 Cygni b, a sub-stellar object approximately 15 times the mass of Jupiter, orbiting its A-type star at 2.4 billion km. This research, led by William Balmer from Johns Hopkins University, explores the deuterium burning limit, challenging definitions of stars and planets. Findings suggest 29 Cygni b formed in a protoplanetary disk, exhibiting both stellar and planetary characteristics.
