WASP-126 and Its Transiting Planet
WASP-126 is a G2 star located 706 light-years away. Its reported mass estimate is 1.12 solar masses, larger than the Sun's, and its reported radius estimate is 1.27 solar radii, also larger than the Sun's. The star is 6.4 billion years old and has a temperature of 5800 K. One planet is known to orbit it.
That planet is WASP-126 b, discovered by transit in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. WASP-126 b has a mass of 90.3 Earth masses, larger than Earth's, and an orbital period of 3.29 days.
