Gaia-1 and Its Giant Planet
Gaia-1 is a star 1190 light-years away with 0.93 solar masses, 0.962 solar radii, and a temperature of 5370 K, which is cooler than the Sun's. One planet orbits this host.
That planet, Gaia-1 b, is a Jupiter-like world discovered by transit in 2022. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. Gaia-1 b completes an orbit every 3.05 days, has a radius of 13.8 Earth radii, and a mass of 534 Earth masses, roughly 1.68 times Jupiter's mass. Its mean density is 1.13 g/cm³, 0.204 times Earth's.
