If Pluto hydrogen gets stripped off by solar winds and other factors then does the Earth's pollution get blown off by solar winds? Is the Earth's pollution affecting Pluto's ice and the whole solar system ?
From Yahoo News this morning...."From 1954 to 2000, Pluto didn't change in color when it was photographed from Earth. But after that, it did. The red levels increased by 20 percent, maybe up to 30 percent, and stabilized from about 2000 to 2002, Buie said. It's not as red as Mars, however, Buie said.
Buie said he can explain the redness, but not why it changed so dramatically and so recently. The planet has a lot of methane, which contains carbon and hydrogen atoms. The hydrogen gets stripped off by solar winds and other factors, leaving carbon-rich areas on the surface, which tend to be red and dark."
