Pluto gets brighter and redder
The people at Hubble say it has to do with the sun melting ice at Pluto’s northern hemisphere as its orbit changes; it does, after all, have a 248-Earth-year orbit.
Personally, I think it’s annoyed that we downgraded it from being a planet. You’ll always be a planet as far as I’m concerned, Pluto (and at least 1.8m other people agree).
