Which planets are the "four donkey kong" in the stars?

After the second pallas Athena was discovered in 1802, the third and fourth Vesta were discovered there in 1804 and 1807. They are all small celestial bodies, which can't be compared with big planets, so it's enlightening: maybe there are many such small celestial bodies there, just call them asteroids. Now there are more than 8,000 known asteroids, but statistics show that the four earliest discovered asteroids are still "giant planets", all with radii above 100 km, and their total mass may account for 80% of the whole asteroid (a ceres may account for 50%). Compared with those asteroids with a diameter of only a few hundred meters or even dozens of meters, they are really huge behemoths.
