HD 155233 b is a confirmed exoplanet orbiting around the K Giant star every 885 days some 244.94 light-years away. It has a mass of 636 Earth masses or 2 Jupiter masses and is likely a gas giant similar of that to Jupiter just double the mass. It was discovered by Wittenmyer et al. on October 22nd 2015.[3][4][5]
Planetary orbit and mass were refined in 2016.[2]
