LTT 1445Ab

LTT 1445Ab is an exoplanet that was discovered in 2019. The planet is located about 22 light years away from Earth and takes 5 days to orbit its star, which in turn orbits two sibling stars, making a total of three stars in the system.[1][2][3]

In 2022, a planetary transmission spectrum has showed no evidence for the atmosphere, although atmosphere with high altitude hazes cannot be ruled out yet.[4]
