It is in a near-Mars orbit. But orbital mechanics are complex, as in addition to the planets going around the sun in a non-circular orbit at different speeds and being bounced around by each other, the sun itself is being spun around an arm of the Milky Way galaxy. So the planets (and everything else spinning around the sun) are actually going through space in a giant corkscrew pattern.
It is amazing they can plot things with the accuracy that they do, given it is really a crap ton of math and most of it is done by gravity. A lot of which is just now (like, within the last 10 years) becoming possible. Because we finally have the computing power to actually chomp through these vast and lengthy calculations within a human's lifetime.
The Tesla Spaceman's solar orbit will no doubt be influenced to some degree by these gravitational forces, especially by our system's gentle giant watchdog, Jupiter, which sends things all over the system wobbling. It even gives the SUN a "tide" of sorts, in the same manner the moon effects our oceans!
And when Jupiter and Saturn are in a line together, which happens every so often, it pulls the sun towards them due to both those gas giants' combined gravity. This happens over a long period, as their solar orbits take much, much longer. When the clockwork is such that Earth finds its way in the middle, we have hotter, harsher weather, which can last for a thousand years. When they are apart, we get colder, dryer weather, which can also last for a thousand years. Ice Ages. Fascinating stuff, and like I said much of this science is still unfolding (we JUST found out more about Pluto last year than we knew from its discovery until then).
You can probably tell I read WAY too much and spend WAY too much time watching the NASA channel, LOL. Still, an interest of mine outside of cars, as few as those interests are.
