With an orbital period of 570 days, it is a relatively cold gas giant planet. Gaia-5b is a brown dwarf orbiting the star Gaia-5, around 134 light-years away from Earth. With a mass of around 21 ...

Gaia-5b is a brown dwarf orbiting the Gaia-5 star, around 134 light-years away from Earth. With a mass of around 21 Jupiters, Gaia-5b is more massive than a planet but too light to sustain nuclear ...

Meanwhile, Gaia-5b, a brown dwarf 21 times the mass of Jupiter, is too massive to be considered a planet but lacks the mass required to ignite nuclear fusion and become a star. This discovery not ...

Gaia-5b sits between planet and star, too small for fusion but too big to be a planet. This cosmic misfit challenges what we know about substellar objects. Astronomers examined 28 possible Gaia ...

The exoplanet, named Gaia-4b, orbits a star 244 light-years away, whereas the Gaia-5b, the brown dwarf – an astronomical object that is intermediate between a planet and a star – orbits a star ...
