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.
And so, Pluto is a dwarf planet. There are still many objects with similar size and mass to Pluto jostling around in its orbit. And until Pluto crashes into many of them and gains mass, it will remain a dwarf planet. Eris suffers from the same problem.
