| Smallest Planet In The Solar System
Before anyone wants to complain about Pluto being the first in the list, I would just like to say I have never been one of those who now believes Pluto is only a planetoid. It will always be the ninth planet for me. Now, if you really want, you can just ignore that one and imagine that Mercury is the smallest planet.
This list shows the diameter, mass and distance from the Sun. Enjoy!
