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.
The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets. The asteroid belt is also termed the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System such as near-Earth asteroids and trojan asteroids. About half the mass of the belt is contained in the four largest asteroids: Ceres, Vesta, Pallas, and Hygiea.
