What is the orbit of the space station?

How long is a year on Mars?
687 daysMars / Orbital period
Since Mars is further from the Sun compared to the Earth, a Martian year is longer: 687 days. That’s just less than two Earth years. Although you wouldn’t age any quicker, living on Mars you’d only be celebrating a birthday roughly every two years, since a birthday is marking another orbit around the Sun.
