How old is a 8-year-old on Pluto?

About 0.03 Pluto years old

On Earth we count years by Earth's orbit (about 365 days).Pluto takes 90560 Earth days per orbit, so someone who has lived 8 Earth years has completed fewer full orbits — hence a different "age."

Pluto was a planet for 76 years (1930-2006) before being reclassified as a "dwarf planet." Kids born before 2006 learned 9 planets, kids after learn 8. The internet EXPLODED with "Save Pluto!" campaigns. But Pluto doesn't care about labels - it's still an amazing world!
