Episode 496 - Dwarf Planets and Massive collisions forming Moons

Dwarf planets are strange objects in our solar systems, but Ceres is unusual amongst that group. Why is Ceres' surface so strange and how could it have formed without a hot core? Ceres is too small to really have a molten core or large molten surfaces. How did Ceres end up with odd plateaus and continent like features without an active core? How could radiation cause Ceres to form in such an odd way? The Moon's relative size is puzzling but how can we prove that it was caused by a colossal collision? Scott D. King, Michael T.
