WASP-47: A Sun-Like Star and Its Four Worlds
WASP-47 is a G9 star located 864 light-years away. It has a mass of 1.11 solar masses and a radius of 1.16 solar radii, with a temperature of 5580 K, cooler than the Sun's. Its age is 6.5 billion years. Four planets orbit this star.
WASP-47 b is a Jupiter-like planet discovered by transit in 2012. Its mass is 374 Earth masses, its radius is 12.9 Earth radii, and its orbital period is 4.16 days. WASP-47 c was discovered by radial velocity in 2015, the method that measures the wobble a planet's gravity induces in its star's motion. It has a reported lower limit of 447 Earth masses and an orbital period of 590 days. WASP-47 d is a Neptune-like planet discovered by transit in 2015, with a mass of 15.5 Earth masses, a radius of 3.65 Earth radii, and an orbital period of 9.03 days. WASP-47 e is a Super-Earth discovered by transit in 2015, with a mass of 9 Earth masses, a radius of 1.83 Earth radii, and an orbital period of 0.79 days.
Among the listed planets, WASP-47 e has the shortest year by reported estimates at 0.79 days, followed by WASP-47 b at 4.16 days. WASP-47 d has the second-longest year at 9.03 days, while WASP-47 c has the longest at 590 days.
