TOI-1742 and Its Super-Earth
TOI-1742 is a star 238 light-years away with an age of 3.9 billion years, a mass of 1.09 solar masses, a radius of 1.13 solar radii, and a temperature of 5820 K. Its reported mass and radius estimates are both larger than the Sun's. One planet orbits this star: TOI-1742 b.
TOI-1742 b was discovered by transit in 2024. It is classified as a Super-Earth, a size class that reaches up to 2.5 times Earth's radius. Its radius of 2.37 Earth radii is larger than Earth's, and its mass of 9.7 Earth masses is likewise larger than Earth's. Its mean density is 4.04 g/cm³, 0.733 times Earth's. The planet completes an orbit every 21.3 days.
