HD 70573 and Its Lone Planet
HD 70573 is a G-type main-sequence star 193 light-years from Earth. Its reported temperature of 5880 K is hotter than the Sun's, and its reported radius of 0.7 solar radii is smaller than the Sun's, though its reported age carries an upper limit of 1 billion years and its mass is 0.9 solar masses.
One known planet orbits the star. HD 70573 b was found in 2007 using the radial velocity method, which detects the wobble a planet's gravity induces in its star's motion. The planet's minimum mass is 1900 Earth masses - roughly 5.98 times Jupiter's mass and larger than Earth's - and it takes 852 days to complete one orbit.
