HD 145377 and Its Planet
HD 145377 is a G0 star 174 light-years away with one known planet. The star is 1.3 billion years old, has 1.12 solar masses, spans 1.14 solar radii, and has a temperature of 6050 K. Its mass and radius estimates are larger than the Sun's, and its temperature is hotter than the Sun's.
HD 145377 b was discovered in 2008 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. The planet has a minimum mass of 1910 Earth masses and an orbital period of 104 days. Its minimum mass is larger than Earth's and roughly 6.02 times Jupiter's mass.
