It was discovered in 2016 and is about 1.5 times the size of Earth. This planet orbits its star every 5.2 Earth days and is believed to be a rocky world. The planet is situated approximately 4.24 light-years away from Earth, making it one of the nearest potentially habitable planets. Its position in the habitable zone suggests that it could have conditions suitable for liquid water, a key ingredient for life as we know it.
