6. One Day = Two Years?
We’ve gotten so used to the fact that one day means 24 hours on Earth, that it’s no wonder that we would subconsciously assume that it’s the same case with other planets of the solar system. But that’s anything but the case.
Consider, for example, the case of Mercury – the closest planet to the Sun. It takes Mars about 58.65 days to make a full rotation on its axis of the sun, while it takes the planet only 88 days to complete a full revolution around the Sun. This means that 1 mercurian day is equal to 2 mercurian years!
