Question
Why is the Kuiper belt considered to be a zone of failed planet formation?A) The dwarf planets found therein have yet to fully accrete all of the material in their orbital paths.
B) There is simply not enough material within the dwarf planet's orbital paths for any of them to ever add up to full planetary status.
C) Because none of the dwarf planets are massive enough to maintain an atmosphere.
D) Both A and B are reasonable.
