Spaceships Floatin' in our Solar System

Snoopy and a Tesla Roadster are the two abandoned vehicles still in space.  Snoopy, the ascent portion of the lunar lander from Apollo 10, swung by the Earth in 2019, just in time for the 50th anniversary of the Apollo 11 landing.  The Tesla, not originally intended to be a space craft, launched in 2018, 'manned' with a SpaceX space suit named 'Starman' in the driver's seat, and orbits the Sun near Mars.

Radiation from the Sun will age them.  Still, the Red Baron and the red Tesla will spin around the solar system, indefinitely, until acted on by another force.  They'll just be sporting a tan.
