If you lived on the dwarf planet Eris, you're really not going to be blowing out the candles all that often. 558 years is how long you'll have to wait between birthdays.

Eris is actually bigger than Pluto, but we can't display a better image than this one as it's further away and no probe has ever gone to visit it.

It is know to have one moon, Dysnomia.
