TOI-1775 and Its Jupiter-Like Planet

TOI-1775 is a star 487 light-years away with an age of 0.8 billion years, a mass of 0.922 solar masses, a radius of 0.829 solar radii, and a temperature of 5280 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 orbits this host.

That planet is TOI-1775 b, a Jupiter-like world discovered by transit in 2024. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. TOI-1775 b has a mass of 96 Earth masses, a radius of 8.05 Earth radii, and an orbital period of 10.2 days. Its reported radius and mass estimates are larger than Earth’s. Its mean density is 1.02 g/cm³, 0.184 times Earth's.
