NGTS-33 and Its Jupiter-Like Planet
NGTS-33 is a star 1430 light-years from Earth, and it hosts one known planet. The star is very young, with an age of 0.03 billion years, a mass of 1.6 solar masses, a radius of 1.47 solar radii, and a temperature of 7440 K. Its mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's.
The sole listed planet is NGTS-33 b, a Jupiter-like world discovered by transit in 2024. It has a mass of 1150 Earth masses, a radius of 18.4 Earth radii, and an orbital period of 2.83 days. Its radius and mass estimates are larger than Earth's, and its mass is roughly 3.63 times Jupiter's mass. Its mean density is 1.02 g/cm³, 0.186 times Earth's.
