TOI-1347: A Nearby Star with Two Super-Earths
TOI-1347 is a star located 481 light-years away. It has a mass of 0.928 solar masses and a radius of 0.84 solar radii. Its temperature is 5490 K, and its age is 0.8 billion years. The star's reported mass estimate is smaller than the Sun's, its reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's. Two planets are known to orbit this host.
TOI-1347 b is a Super-Earth discovered by transit in 2024. It has a mass of 11.1 Earth masses and a radius of 1.8 Earth radii. Its orbital period is 0.847 days. Among the listed planets, TOI-1347 b has the shortest year by reported estimates (0.847 days) and the largest radius by reported estimates (1.8 Earth radii). Its reported mass estimate is larger than Earth's, and its reported radius estimate is larger than Earth's. Its mean density is 10.5 g/cm³, 1.9 times Earth's.
TOI-1347 c is a Super-Earth also discovered by transit in 2024. It has a reported upper limit of 6.4 Earth masses and a radius of 1.6 Earth radii. Its orbital period is 4.84 days. Among the listed planets, TOI-1347 c has the longest year by reported estimates (4.84 days) and the smallest radius by reported estimates (1.6 Earth radii). Its reported radius estimate is larger than Earth's.
