HD 194490 b: A Giant Planet Around a Single Star

HD 194490 is a star 262 light-years away with one known planet. The host star has a mass of 1.06 solar masses, a radius of 1.15 solar radii, and a temperature of 5860 K. Its radius is larger than the Sun's.

The planet HD 194490 b was discovered in 2022 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its mass is 3560 Earth masses, roughly 11.2 times Jupiter's mass and larger than Earth's. HD 194490 b orbits its star with an orbital period of 13100 days.
