Planet Found in Habitable Zone Around Nearest Star

[Anomalocaris]

The other thing to keep in mind is although Proxima Centauri, and presumably this planet, is approximately the same age as earth's sun, Proxima Centauri's expected life on the main sequence is 3 trillion years, while the sun has only about 5 billion years go. The total time this planet will spend inside the habitable zone is approximately 400 times longer than the entire expected life of our solar system. So there may well be possibilities for what can happen on this planet over its enormously long expected life that we have not even begun to consider.
