NGTS-30 b: A Jupiter-Like World in a Distant Star System
NGTS-30 is a star located 777 light-years from Earth. It has a mass of 0.94 solar masses and a radius of 0.913 solar radii, making it slightly smaller than the Sun. Its temperature is 5460 K, which is cooler than the Sun, and it is 1.1 billion years old. One planet orbits this host.
That planet is NGTS-30 b, a Jupiter-like world discovered in 2024 by the transit method, in which a planet passing in front of its star causes a small dip in observed brightness. NGTS-30 b has a mass of 305 Earth masses and a radius of 10.4 Earth radii, both larger than Earth's corresponding values. Its mean density is 1.49 g/cm³, which is 0.271 times Earth's. The planet completes one orbit every 98.3 days.
