How old would I be on Mars if I was 12?
A year on Mars is longer than a year on Earth—almost twice as long at 687 days. This is roughly 1.88 times the length of a year on Earth, so to calculate your age on Mars we simply have to divide your Earth age by 1.88.
Who is the oldest planet?
Jupiter formed in a geologic blink. Its rocky core coalesced less than a million years after the beginning of our solar system, scientists reported Monday in the Proceedings of the National Academy of Sciences.
Why does Mars have a longer year than Earth?
The oldest calendars on Earth have a 30-day month and 12 of them produce a 360 day year. If the Earth spun slightly slower, let’s say at exactly the speed Mars spins, there would be 360 days in a year on Earth. The protractor has an unusual number of degrees to it. 360 degrees.
