TOI-2641: A Distant Star With a Close-Orbiting Giant

TOI-2641 is an F9 V star located 1120 light-years away. Its spectral type places it among the hotter and more massive stars than the Sun, and it is estimated to be 10.8 billion years old. The star's mass is 1.16 solar masses and its radius is 1.34 solar radii, both larger than the Sun's corresponding values. Its temperature is 6100 K, hotter than the Sun's.

One planet orbits this star: TOI-2641 b, discovered in 2023 by the transit method, which detects the small dip in starlight caused when a planet passes in front of its star from our viewpoint. TOI-2641 b is a Jupiter-like planet, with a radius of 18.1 Earth radii and a mass of 123 Earth masses, larger than Earth in both radius and mass. Its mean density is 0.114 g/cm³, which is 0.0207 times Earth's. It orbits its host every 4.88 days.
