This is a "bloated planet" with an extremely low density. With a radius 1.37 times that of Jupiter , its mass is only 19% of the Jupiter [1] . Thus, the density of the planet is approximately the same as that of styrene foam . The surface temperature is 1712 +51
−46 K [1] . It was discovered in 2016.
