TOI-1453 and Its Two Planets
TOI-1453 is a star 257 light-years from Earth with two known planets. The star is 12 billion years old, has a mass of 0.715 solar masses, a radius of 0.72 solar radii, and a temperature of 4980 K. Its mass, radius, and temperature are all smaller or cooler than the Sun's.
Both planets were discovered by transit in 2025. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness.
TOI-1453 b is classified as Earth-like. It has an orbital period of 4.31 days, a radius of 1.17 Earth radii, and a reported upper limit mass of 2.32 Earth masses. Its radius is larger than Earth's. Among the listed planets, it has the shortest year and the smallest radius.
TOI-1453 c is classified as a Super-Earth. It has an orbital period of 6.59 days, a mass of 2.95 Earth masses, and a radius of 2.22 Earth radii. Its mass and radius are both larger than Earth's, and its mean density is 1.48 g/cm³, which is 0.268 times Earth's. Among the listed planets, it has the longest year and the largest radius.
