HD 38283 and Its Planet
HD 38283 is a G0 star 124 light-years away. Its spectral type places it in the same broad temperature class as the Sun. The star has a mass of 1.1 solar masses, a radius of 1.49 solar radii, and a temperature of 5980 K. Its reported radius estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's.
One planet is known to orbit this star: HD 38283 b. It was discovered in 2010 using 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. HD 38283 b has a minimum mass of 127 Earth masses, larger than Earth's, and an orbital period of 363 days.
