Total mass of asteroids ~mass of Moon • "families" of asteroids have similar color, spectra & orbits Which explanation for the belt seems the most plausible? There wasn't enough material around to form a planet. The belt is the remnant of a large terrestrial planet that used to be between Mars and Jupiter, and broke up Some process prevented the planetesimals from becoming a planet But WHY didn’t they form a little planet? Not true! There was lots of material either side to make Mars and Jupiter - why a gap in the solar nebula?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
