Space is vast. So vast, in fact, that we measure interstellar distances in “light-years” — that is, the distance light (the fastest thing in the universe) travels in an entire year. In other words, that’s 299,792,458 meters per second! That’s an insanely long stretch of travel, but the good news is that one of the closest habitable planets has been discovered. It’s only 31 light-years away to boot, so it’ll only take us around 500,000 years to reach! Ready to pack your bags?
