TOI-677: A Planet Orbiting a Nearby Star
TOI-677 is a star 463 light-years away with a spectral type of F8. Its age is 2.92 billion years, its mass is 1.18 solar masses, its radius is 1.28 solar radii, and its temperature is 6300 K. The star's reported mass estimate is larger than the Sun's, its reported radius estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's. One planet is known to orbit this host.
TOI-677 b is a Jupiter-like planet discovered by transit in 2020. Its orbital period is 11.2 days, its radius is 13.1 Earth radii, and its mass estimate is 392 Earth masses, which is roughly 1.23 times Jupiter's mass and larger than Earth's. Its radius estimate is also larger than Earth's, and its mean density is 0.958 g/cm³, 0.174 times Earth's.
