HD 196050 and Its Planet
HD 196050 is a star 165 light-years from Earth with a G0 spectral type, placing it in the same broad temperature class as the Sun. It has an age of 3.5 billion years, a mass of 1.2 solar masses, a radius of 1.3 solar radii, and a temperature of 5910 K. Its reported mass and radius estimates are both larger than the Sun's, and its reported temperature is hotter than the Sun's. One planet has been found orbiting this host.
That planet, HD 196050 b, was discovered in 2002 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. It has a mass of 1490 Earth masses, making its reported mass estimate larger than Earth's and roughly 4.7 times Jupiter's mass. It completes one orbit every 1390 days.
