HD 87883 and Its Single Known Planet
HD 87883 is a K0 star located 59.7 light-years away. Its reported age is 9.84 billion years, and it has one known planet. The star's mass estimate is smaller than the Sun's, its radius estimate is also smaller, and its temperature is cooler than the Sun's. Its reported mass is 0.8 solar masses, its radius is 0.78 solar radii, and its temperature is 4960 K.
The one planet orbiting this star is HD 87883 b. It was discovered in 2009 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. Its reported mass is 2010 Earth masses, which is larger than Earth's and roughly 6.31 times Jupiter's mass. Its orbital period is 3010 days.
