And that's assuming just toggles, if each parameter has 10 levels you only need 12, then add one toggle and you get trillions. Heck, I can name 12 parameters that have at least 10 different values off the top of my head:

1. Amount of water overall (oceans and lakes)
2. Amount of mountains
3. Amount of Forrest on the land
4. Amount of life forms
5. Temperature
6. Amount of moons/rings
7. Size
8. Amount of rivers
9. Whether the landmass is one big continent or multiple small islands
10. Amount of volcanoes
11. Amount of caves
12. Amount of iron (or any other resource)

Congrats, if you now add a does the planet rotate toggle you've created trillions of planets.
