An enormous exoplanet, HD 106906 b, has been discovered, measuring 11 times the mass of Jupiter and orbiting its star at a distance 650 times greater than that between Earth and the sun. This finding challenges existing theories about the formation of such massive planets at such great distances. The planet's size raises questions regarding its classification, as it approaches the mass range for deuterium fusion, typically associated with brown dwarfs. Researchers note that while there is no universal standard for distinguishing between planets and brown dwarfs, the mass limit for deuterium fusion is around 11 to 13 Jupiter masses. The discovery prompts further investigation into the nature and formation processes of such distant and massive celestial bodies.
