HD 88133 and Its Planet
HD 88133 is a star 240 light-years away with one known planet. Its spectral type is G5 IV, and it is 6.88 billion years old. The star has a mass of 1.12 solar masses and a radius of 1.85 solar radii, with a temperature of 5450 K. Its reported mass and radius estimates are larger than the Sun's, while its reported temperature is cooler than the Sun's.
The planet HD 88133 b was discovered in 2004 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. The planet's minimum mass is 90.4 Earth masses, larger than Earth's, and it completes an orbit every 3.41 days. This minimum mass is a lower bound on the planet's true mass.
