size of our sun. That still leaves between 40–80 billion stars much like the sun. If one in five of those has an Earth-like planet, that means there may be between eight and sixteen billion Earth-like planets in the Milky Way. Of course these numbers may be off. The number of sun-like stars may be lower, or higher. The number of Earth-like planets may be more, or less. We just can’t know, so far. Further, there is no reason to assume that only stars like our sun will have planets capable of supporting life. Or that only a planet will support life. There may be intelligent life on a large moon of a gas giant exoplanet in the “Goldilocks zone” of a red dwarf. There is also no way to know how typical the Sol system is with it’s eight planets, half of which are ice or gas giants, and half of which are small rocky planets like Earth. Most of the exoplanets we know about are gas giants like Jupiter, just because they are easier to detect. Remember, we haven’t actually “seen” any exoplanets. We only know they are there by the way their gravity affects their home stars, causing a wobble, or they are aligned with Earth such that the transit of the planet between Earth and its star causes the star to flicker. Small, rocky planets like Earth are just harder to find. So there may be lots of them, or not. We just don’t know, yet.
