      Forward?
      Along an elliptic trajectory around the sun?

      … it really depends on where you sit and how you look at it …

      Mars orbits the Sun the same way the Earth does, although further out so the year is almost 2 Earth years – on your 18th birthday on Earth you would only be 9 and a half in Mars years.

      People used to think that the planets like Mars did loop the loops, and came up with complicated ways to explain why. In fact, what happens is that both Earth and Mars are orbiting the Sun at different speeds, so sometimes the Earth is catching up and sometimes it’s passing Mars, which makes Mars do loops in the sky.
