Confirmation of a second closest habitable zone super-Earth around nearby star Lacaille 9352 (GJ 887)

Star system: Lacaille 9352 | Distance from the Sun: 10.7 light years

Astronomers have confirmed a complex multiplanet system orbiting Lacaille 9352 (also Gliese 887, HD 217987) - a bright red dwarf star only 11 light years away. Using high-precision instruments, the team identified two new worlds: a small planet roughly the mass of Earth with a very short 4-day orbit, and a larger 'super-Earth' located within the star's habitable zone, where temperatures could allow for liquid water. 

This super-Earth, which takes about 51 days to orbit its sun, is now recognized as the second closest habitable-zone planet to our own Solar System. The study also hints at a fifth possible planet—potentially only half the mass of Earth—highlighting how packed and diverse planetary systems can be around stars much smaller and cooler than our Sun.
