I've been building my own story world with my friend which revolves around humans and different intelligent beings, and for one of the beings, I've come up with a planet and a solar system that is filled with mineral resources, and basically export of said resources is one of the ways they earn income.
For the planet itself, I've been thinking about a bit of a smaller planet than earth which is mountainous has less ocean coverage than the earth, and has many rivers and lakes which make agriculture possible. The planet is a bit closer to the sun making it be just a bit hotter than the earth, it has two moons one of them being 1.2x smaller than the moon and the other being not even half its size.
The planet is the second planet from the sun, the first planet is a little bigger than it, and the distance between the two is pretty big, this planet has a lot of iron/metallic minerals and has two moons which are just rocky moons
The third planet is a giant planet which is not too far from the inhabited planet, it's vulcanic and has geodes of minerals along with 8 moons with some of them being filled with oil
After that is a huge asteroid belt filled with precious minerals
After the asteroid belt, there are two other planets, the first one is a planet that's a bit bigger than earth and has an icy surface with some minerals. The next planet is a Neptune-like planet.
I wanna know would this work or am I asking too much with this many minerals?
Also, I'm pretty new to this so sorry if this is messy;-;
