WASP-154 and Its Jupiter-Like Planet
WASP-154 is a star 703 light-years away with one known planet. Its reported mass estimate is 0.8 solar masses and its radius estimate is 0.823 solar radii, both smaller than the Sun's. The star's reported temperature is 4770 K.
The system's only listed planet is WASP-154 b, 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-154 b has a mass estimate of 199 Earth masses, or larger than Earth's, and a radius estimate of 10.8 Earth radii. Jupiter-like planets exceed 4 times Earth's radius. Its orbital period is 3.81 days. Its mean density is 0.88 g/cm³, 0.16 times Earth's.
