Planet TOI-3688 A b in a Distant Two-Star System
TOI-3688 A is a star 1290 light-years away with a radius of 1.3 solar radii and a mass of 1.2 solar masses. Its reported mass and radius estimates are larger than the Sun's, and its temperature of 5950 K is hotter than the Sun's. The star is 3.3 billion years old. One planet orbits this host.
TOI-3688 A b is a Jupiter-like planet discovered by transit in 2023, meaning it was found when it passed in front of its star and caused a small dip in observed brightness. The planet's orbital period is 3.25 days. Its radius is 13.1 Earth radii, larger than Earth's, and its mass is 311 Earth masses, also larger than Earth's. Its mean density is 0.767 g/cm³, 0.139 times Earth's.
