WASP-77 A and Its Planet
WASP-77 A is a G8 V star 343 light-years away. It is a Sun-like dwarf with an age of 6.2 billion years, a mass of 0.903 solar masses, a radius of 0.91 solar radii, and a temperature of 5620 K. Its reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's. One planet is known to orbit this host.
WASP-77 A b was discovered by transit in 2012. It has a mass of 529 Earth masses and an orbital period of 1.36 days. Its mass estimate is larger than Earth's and roughly 1.67 times Jupiter's mass.
