      Nice question! Well, there’s now only 8 planets in our solar system (I really miss Pluto!) and so far we’ve discovered 786 planets outside of our own solar system. I’d hazard a guess that there’s waaaay more than that in our galaxy, but they’re really hard to find. Here’s a picture of them all:
