HD 195019 b is an exoplanet orbiting around HD 195019 in the binary star system. It has a minimum mass of 3.7 MJ. It orbits very close to the star. Like many planets at close distance, its orbit is circular, even more circular or less eccentric than Earth. It takes 437 hours to orbit with velocity of 83.24 kilometers per second.[1]
