[00:00:00]Did you know the closest planet that could support life is over four light years away? It's called Proxima B, a rocky world orbiting the nearest star to our solar system. It lies in the habitable zone where temperatures may allow liquid water to exist. That makes it one of the best places we've found for possible life. But here's the problem. Even with our fastest spacecraft, reaching it would take tens of thousands of years. The nearest possible new home for humanity is still impossibly far away.
