TIC 172900988 Aa and Its Circumbinary Planet
TIC 172900988 Aa is an F9 star located 819 light-years away. Its mass is 1.24 solar masses, its radius is 1.38 solar radii, and its temperature is 6050 K. It is estimated to be 3.1 billion years old. One known planet orbits this host.
That planet is TIC 172900988 b, discovered by transit in 2021. It is a Jupiter-like planet, a class that exceeds 4 times Earth's radius, with a radius of 11.3 Earth radii, larger than Earth's. Its mass is 942 Earth masses, also larger than Earth's and roughly 2.96 times Jupiter's mass. Its mean density is 3.65 g/cm³, 0.662 times Earth's. The planet's orbital period is 200 days.
TIC 172900988 b is circumbinary, orbiting both stars of a binary system rather than one star alone.
