Check out what, exactly? The Tesla Roadster was the test payload for the very first ever launch of the falcon heavy rocket. There were no launch customers, so musk said fuck it, and launched his Roadster and a bunch of ballast.

The Roadster was placed into a heliocentric orbit (orbiting the Sun), which crosses the orbits of both Earth and Mars. The initial plan was to send the car into an orbit around Mars, but due to a higher-than-expected final burn from the rocket, it ended up in an orbit that extends beyond Mars’ orbit and goes further into the asteroid belt at its farthest point from the Sun.

The orbit is elliptical and ranges between a perihelion (closest point to the Sun) near Earth’s orbit and an aphelion (farthest point) that reaches slightly beyond Mars, but it's not a stable orbit around Mars itself.
