Is Pluto a planet? The answer is about a lot more than the downgraded 'runt' of the solar system Since 1930, we've discovered that Pluto is one of the solar system's most fascinating worlds. It features blue skies, red snow, glaciers made of frozen nitrogen, and dunes made of frozen methane grains. And circling it all are no fewer than five moons!
