TOI-2445 and Its Earth-like Planet
TOI-2445 is a star 158 light-years from Earth, and it hosts one known planet. The star's reported mass estimate is 0.245 solar masses and its radius is 0.272 solar radii, both smaller than the Sun's. Its temperature of 3330 K is cooler than the Sun's.
The planet TOI-2445 b was discovered by transit in 2022. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. TOI-2445 b has an orbital period of 0.371 days and a radius of 1.25 Earth radii. Its radius is larger than Earth's, and it is classified as Earth-like, meaning it stays within 1.5 times Earth's radius.
