NGTS-15 and Its Jupiter-Like Planet
NGTS-15 is a G6 V star, a main-sequence dwarf somewhat cooler than the Sun, with a reported temperature of 5600 K. It lies 2570 light-years away and has an age of 3.28 billion years. Its mass is 0.995 solar masses and its radius is 0.954 solar radii. One planet is known to orbit this star.
That planet, NGTS-15 b, was discovered in 2021 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. NGTS-15 b is classified as Jupiter-like, a size class that exceeds 4 times Earth's radius. Its radius is 12.3 Earth radii, larger than Earth's, and its mass estimate is 239 Earth masses. Its orbital period is 3.28 days.
NGTS-15 b has a mean density of 0.702 g/cm³, 0.127 times Earth's.
