TOI-2019 b: A Distant Jupiter-like World
TOI-2019 is a star 646 light-years away with a mass of 1.18 solar masses and a radius of 1.75 solar radii, both larger than the Sun's. Its temperature of 5630 K is cooler than the Sun's, and it is 6.4 billion years old. One planet orbits this host.
That planet, TOI-2019 b, is a Jupiter-like world discovered by transit in 2024. It has a radius of 5.33 Earth radii, larger than Earth's, and a mass of 34.4 Earth masses, also larger than Earth's. Its mean density is 1.25 g/cm³, 0.227 times Earth's. The planet completes an orbit every 15.3 days.
