00:00On Mercury, a single day is longer than its entire year.
00:04How is that possible?
00:10Mercury orbits the Sun in just 88 Earth days.
00:14That's its year.
00:15But it spins on its axis incredibly slowly,
00:19once every 59 Earth days.
00:26Because of this slow spin and a gravitational quirk
00:30called a 3 to 2 resonance,
00:32sunrise to sunrise on Mercury takes 176 Earth days.
00:42That's two full Mercurian years packed into one solar day.
00:47Imagine waiting half a year for lunch.
