Asteroid
Although their location in the asteroid belt excludes them from planet status, the three largest objects, Ceres, Vesta, and Pallas, are intact protoplanets that share many characteristics common to planets, and are atypical compared to the majority of "potato"-shaped asteroids. The fourth largest asteroid, Hygiea, has an undifferentiated interior, like the majority of asteroids. Between them, the four largest asteroids constitute half the mass of the asteroid belt.
Mario Jurić
Together with prolific amateur astronomer Korado Korlević, Jurić has co-discovered 125 asteroids, and one comet, 183P/Korlević-Jurić. He took part in discovery of the Sloan Great Wall, at the time the largest known structure in the Universe. His co-discovery, the Koronian asteroid 22899 Alconrad is one of the smallest known binary asteroids in the main-belt.
