If you dont have so much cores then read this will help you so if you want to mod a primed mod to rank 10(max) it cost 528 Gold Cores but if you want to mod it till rank 9 it cost 264 Gold Cores so you can mod 2 mods till rank 9 or 1 till rank 10 and the difference is like 10 % or so I prefer to u mod 2 mods till rank 9 and not till rank 10.
Ceres, the asteroid belt's only dwarf planet, is about 950 km in diameter, whereas 4 Vesta, 2 Pallas, and 10 Hygiea have mean diameters of less than 600 km. The remaining bodies range down to the size of a dust particle.
A planet is an object that has cleared its space (i.e., there is nothing comparable in size around it). Therefore anything in the asteroid belt or the Kuiper belt (where Pluto is) can be a planet. They came up with a new term: dwarf planet, but decided that dwarf planets are not planets, just big asteroids!
