geology - remnant planetesimal
 

I'm soooo lost on this question I have. I have looked all of the internet and can not find anything about it.



Nearly all of the mass in our Solar System become concentrated into our Sun, but a tiny left-over proportion (called planetesimals) became the planets. Only one object between Pluto and our Sun is considered to be a remnant planetesimal. That object is ...



1. Venus.

2. Mercury.

3. Uranus.

4. Ceres.

Since it seems to me that three of those are planets and not planetesimals, I would say Ceres.
