TIC 237913194 b: A Jupiter-Like Planet Around a Sun-Like Star

TIC 237913194 is a G3 star some 998 light-years away, with a mass of 1.03 solar masses, a radius of 1.09 solar radii, and a temperature of 5790 K. Its age is 5.7 billion years. One planet is known to orbit this host.

That planet, TIC 237913194 b, was discovered in 2020 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. It orbits every 15.2 days. Its radius of 12.5 Earth radii places it in the Jupiter-like class, defined as exceeding four times Earth's radius, and its reported radius estimate is larger than Earth's. Its mass estimate is 617 Earth masses, larger than Earth's and roughly 1.94 times Jupiter's mass. Its mean density is 1.73 g/cm³, 0.314 times Earth's. The star's reported radius estimate is larger than the Sun's.
