NGTS-31 and Its Lone Planet
NGTS-31 is a star 1620 light-years away with an age of 9.97 billion years, a mass of 0.96 solar masses, a radius of 1.7 solar radii, and a temperature of 5710 K. One planet orbits this host.
That planet is NGTS-31 b, a Jupiter-like world discovered by transit in 2025. It completes an orbit every 4.16 days. Its radius of 18 Earth radii is larger than Earth's, and its mass of 356 Earth masses is also larger than Earth's, roughly 1.12 times Jupiter's mass. Its mean density is 0.334 g/cm³, 0.0606 times Earth's.
