Twenty years ago, we didn't know if there were any planets orbiting stars other than our own. Today, it's estimated that each of the roughly 100-billion stars in our galaxy has, on average, 1.6 planets orbiting around it, as this video from astronomers and science-communicators Tony Darnell and Scott Lewis explains.
Did we mention that one in five of the sun-like stars in the Milky Way is theorized to be orbited by potentially habitable, Earth-like worlds? That puts the number of potentially habitable, Earth-size worlds in the Milky way at a conservative estimate of two-billion. How's that for a sense of perspective on one's place in the Cosmos?
