Size comparison Earth, the Moon and Pluto

Size comparison Earth, the Moon and Pluto

Here we have the Earth with a mean radius of 6,371 kilometers, our Moon with a mean radius of 1,737 kilometers (0.273 Earths) and Pluto with a mean radius of 1,185 kilometers (0.18 Earths).

Pluto has about the same surface area as Russia and a surface gravity of only 0.067g. Its mass is less than 0.24 percent that of Earth. The slightlyreddish tint is likely caused by hydrocarbon molecules (Tholins) that are formed when cosmic rays and solar ultraviolet light interact with methane in Pluto’s atmosphere and on its surface.

  • It’s not a mistake, I’ve seen Pluto = Di beorfe, but I cant explain it, and neither can an initial google. I got 23 across as I remembered puzzling over Pluto = Di with my uncle, BC, a few months ago. Can anyone out there help?
