BD-11 4672 and Its Two Known Planets
BD-11 4672 is a K7 V star, a K-type main-sequence dwarf, located 88.6 light-years away. It hosts two known planets. The star's reported mass estimate is 0.651 solar masses, smaller than the Sun's, and its reported radius estimate is 0.639 solar radii, also smaller than the Sun's. Its reported temperature is 4550 K, cooler than the Sun's, and its age is 7.4 billion years.
Both planets were found by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. BD-11 4672 b was discovered in 2014. Its minimum mass is 207 Earth masses, larger than Earth's, and its orbital period is 1630 days. Among the listed planets, BD-11 4672 b has the largest minimum mass and the longest year by reported estimates.
BD-11 4672 c was discovered in 2020. Its minimum mass is 15.4 Earth masses, larger than Earth's, and its orbital period is 74.2 days. Among the listed planets, BD-11 4672 c has the smallest minimum mass and the shortest year by reported estimates, at 74.2 days.
