HD 45350 and Its Planet

HD 45350 is a G-type dwarf star 153 light-years away, described by a spectral type of G5 V. It is 8 billion years old, holds 1.02 solar masses, and has a temperature of 5620 K. Its reported mass estimate is larger than the Sun's, while its reported temperature is cooler. One planet is known to orbit this host.

That planet, HD 45350 b, was found in 2004 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its minimum mass is 569 Earth masses, or roughly 1.79 times Jupiter's mass, which is larger than Earth's. It completes one orbit every 964 days.
