HD 210193 b: A Radial Velocity Planet Around a Sun-Like Star
HD 210193 is a G3 V star 138 light-years away, making it a Sun-like main-sequence dwarf. The star has 1.06 solar masses, a radius of 1.03 solar radii, and a temperature of 5850 K. One planet orbits this host.
HD 210193 b was discovered in 2019 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. The planet's minimum mass is 153 Earth masses, larger than Earth's, and it completes one orbit every 650 days. A minimum mass is a lower bound on a planet's true mass.
