There are eight planets, 166 known moons bound to them, three dwarf planets and their 4 moons. And billions of small bodies in our solar system alone. That includes asteroids, belt objects, comets and meteors. That's the solar system.
As of this year, there's 271 discovered known (which indicates there's probably hundreds, if not thousands) extra-solar planets, which means planets outside of our system. And studies show MOST of them are actually of the same size as Jupiter, if not bigger. And Jupiter is the biggest planet in our system.
If that isn't enough, there's 76 unconfirmed exoplanets. If the 52 that are extremely likely to be confirmed are confirmed, then that would put the tally at 323 planets outside of our solar system. There's over 100 billion galaxies in the observable universe and at the very least, 70 sextillion(7×1022) stars in the observable universe.
And what are the odds that there is no life on any of them?
By aliens, I just mean intelligent life forms.
