A Few Interesting Facts About Ol’ Pluto

I didn’t know that. I also checked out the source for that info and found out some other cool things about the demoted dwarf planet:

– The name Pluto was originally suggested by an 11-year-old schoolgirl in Oxford, England.

– No spacecraft has ever visited Pluto, though one is due to reach there in 2015.

– Pluto has three moons: Charon, Nix and Hydra, though Nix and Hydra are really tiny.

– Similarities between Pluto and Triton (one of Neptune’s moons) has led to the idea that Triton may have once been similarly independent and orbiting the Sun like Pluto and Charon, and was later captured by Neptune. All three object may be the last of their kind, the rest of which were ejected into the Oort cloud.

Pluto’s cool (like literally, the surface temperature ranges form -235 to -210 degrees Celsius or 38 to 63 Kelvin) so let’s not forget him, despite being a ‘dwarf planet’.
