TOI-1442 and Its Earth-like Planet

TOI-1442 is a star 134 light-years from us. Its reported mass estimate is 0.287 solar masses and its reported radius estimate is 0.309 solar radii, both smaller than the Sun's. The star's reported temperature is 3330 K, cooler than the Sun's. One planet has been found orbiting this host.

That planet, TOI-1442 b, was discovered by the transit method in 2022. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness; repeated dips help establish orbital periods. TOI-1442 b completes an orbit every 0.409 days, and its reported radius estimate is 1.17 Earth radii, larger than Earth's. Classified as Earth-like, it falls within the size class that stays within 1.5 times Earth's radius, a classification based on radius rather than composition.
