What Makes a ‘Day’ on Earth Different from a ‘Day’ on Mars?

A day is the time it takes for a planet to turn all the way around once. On Earth, we feel a day as about 24 hours, but on Mars, it’s more like 24 hours and 39 minutes! That tiny extra time might not sound like much, but over time, it changes how people live and sleep if they’re on Mars.

Examples

  1. Imagine living on Mars, every day feels like it takes an extra minute to turn.
  2. If you're watching the Sun from Earth and Mars, you’ll notice that it rises just a little later each day on Mars.
  3. Your Martian friend might go to bed at 10 PM and wake up at 10:39 PM, just because of how slowly Mars turns.
