Which outer planet is all rock?
No outer planet that we currently know of is all rock. If this is a trivia/homework question the intended response is most likely either Mars or Pluto, but there are problems with each of these: Pluto is a dwarf planet, not a planet. This might be considered quibbling, but there's a more significant problem: using Pluto as the answer would require an unusually generous definition of the term "rock" (Pluto's average density of 1200 kg/m3 is too low for it to be rock; it's mostly made of ice). Mars IS definitely a planet, and it IS mainly rock, with some metals and just a little bit of ices; however, it's not an OUTER planet (Mars is the outermost of the inner planets).
