HD 90156 and Its Planet
HD 90156 is a G5V star 71.6 light-years from Earth. It is a Sun-like dwarf with a reported mass estimate of 0.94 solar masses, a radius estimate of 0.9 solar radii, and a temperature of 5630 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler. The star is 2.6 billion years old, and one planet has been found orbiting it.
That planet, HD 90156 b, was discovered in 2011 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 18 Earth masses, larger than Earth's minimum-mass comparison, and its orbital period is 49.8 days.
