WASP-145 A and Its Jupiter-like Planet
WASP-145 A is a K2 V star 298 light-years away. This main-sequence dwarf has a mass of 0.76 solar masses and a radius of 0.68 solar radii, both smaller than the Sun's. Its temperature of 4900 K is cooler than the Sun's, and it is 6.99 billion years old. One planet orbits this host.
That planet, WASP-145 A b, was discovered by transit in 2018. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. WASP-145 A b orbits every 1.77 days.
It is a Jupiter-like planet, a size class that exceeds 4 times Earth's radius. Its radius is 10.1 Earth radii, larger than Earth's. Its mass is 283 Earth masses, also larger than Earth's. Its mean density is 1.52 g/cm³, 0.276 times Earth's.
