NGTS-27 b: A Jupiter-Like Planet
NGTS-27 is a star 3070 light-years away with an age of 7.9 billion years. Its mass is 1.07 solar masses and its radius is 1.77 solar radii, both larger than the Sun's corresponding values, and its temperature is 5700 K. One planet orbits this host.
That planet is NGTS-27 b, a Jupiter-like world discovered by transit in 2024. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. NGTS-27 b has a mass of 188 Earth masses, larger than Earth's, and a radius of 15.6 Earth radii, also larger than Earth's. Its orbital period is 3.37 days, and its mean density is 0.271 g/cm³, 0.0492 times Earth's.
