TYC 8998-760-1 and Its Two Imaged Planets

TYC 8998-760-1 is a K3 IV star located 309 light-years away. It is a very young star, with an age of 0.0167 billion years. Its mass is 1 solar masses, and its temperature is 4570 K, which is cooler than the Sun's. Two planets are known to orbit this host.

The first, TYC 8998-760-1 b, was discovered by imaging in 2020. No orbital period is reported for it.

The second, TYC 8998-760-1 c, was also discovered by imaging in 2020 and is classified as Jupiter-like. Its mass is 1910 Earth masses, or roughly 6 times Jupiter's mass, and its radius is 12.3 Earth radii; both estimates are larger than Earth's. Its mean density is 5.61 g/cm³, 1.02 times Earth's.

No orbital period is reported for TYC 8998-760-1 c.
