WASP-155 and Its Lone Known Planet
WASP-155 is a star located 1300 light-years away, and it hosts one known planet. The star is 1.7 billion years old and has a mass of 1.09 solar masses, a radius of 1.24 solar radii, and a temperature of 5660 K. Its mass and radius are both larger than the Sun's, while its temperature is cooler.
The planet WASP-155 b is a Jupiter-like world discovered by transit in 2025. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. WASP-155 b has a mass of 277 Earth masses, a radius of 13.5 Earth radii, and an orbital period of 3.11 days. Its radius is larger than Earth's, as is its mass. Its mean density is 0.627 g/cm³, 0.114 times Earth's.
