Why Ganymede and Titan ought to be Planets

This chart shows all the objects in the solar system with a
diameter larger than 200 miles.

Note that the diameter of Mars, everyone’s favorite "next step in exploration" is
less than 1000 miles more than that of Ganymede and just over 1000 miles
more than that of Titan. Both Ganymede and Titan are bigger than
Mercury, and it’s not even a dwarf planet.
Titan even has an atmosphere, mostly nitrogen just like Earth.

I think if I can print this, I just found a new wall decoration for my office.
