This is so cool. We’ve found a likely “habitable” planet revolving around its own red sun. The sun is closer than ours (a year there would be 13 days) and there would be a large red star in view every day which would be an amazing site to see. Temperature is expected to be between 0 degrees and 40 degrees (celcius) which means ice/water would be in liquid-form- which is great for the possibility of life. The planet is very close to us in the solar system- just 20.5 light years away. Imagine how many other earth-like planets there must be out there since we’ve already found one so close to us.
