NGTS-23 b: A Giant Planet Orbiting an F9 V Star
NGTS-23 is a star 3510 light-years away, with a spectral type of F9 V. The star is 6.39 billion years old, holds 1.01 solar masses, and spans 1.24 solar radii, making its reported radius estimate larger than the Sun's. Its temperature of 6060 K is hotter than the Sun's. One planet orbits this host.
That planet is NGTS-23 b, a Jupiter-like world discovered by the transit method in 2022. It orbits every 4.08 days, has a mass of 195 Earth masses, and a radius of 14.2 Earth radii. Its radius exceeds four times Earth's, and both its reported radius and mass estimates are larger than Earth's. Its mean density is 0.375 g/cm³, 0.068 times Earth's.
