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.
Dwarf planets also are generally smaller than the planet Mercury. The first five recognized dwarf planets are Ceres, Pluto, Eris, Makemake and Haumea. Scientists believe there may be dozens or even more than 100 dwarf planets awaiting discovery. The IAU recognized Pluto's special place in our solar system by designating dwarf planets that orbit the sun beyond Neptune as plutoids. Eris, which orbits far beyond Neptune, is a plutoid while Ceres, which orbits in the main asteroid belt between Mars and Jupiter is a dwarf planet. Read More: Mike Brown's Dwarf Planet Page (Caltech)
