How many complete orbits has Earth make in your lifetime? How many orbits has Mars made in your lifetime?

With your first question, which planets are closer to the sun than the earth?

For the second, how old are you? The earth makes one orbit per year.

I searched Google under the key words "Mars orbit cycle" to get this information:

The Martian year is 1.88 tropical Earth years consisting of 668.59 Martian days (sols) or 686.98 Earth days. (This means that Mars only has a fraction of an orbit during each Earth year.)

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps. Thanks for asking.
