It’s already happened once. A couple years ago some astronomer spotted a small asteroid with a high albedo (it was very reflective, brighter than normal).
Some Internet folks verified, and with a few more observations they were able to calculate its orbit.
Turns out the orbit matched that of the Tesla shot into space. The high albedo would make sense as the Tesla is still connected to the falcon 9 upper stage, which is painted all white.
Heliocentric orbit like this:

That’s actually pretty cool. That thing might be forgot about and then found again 10,000 years from now

You factor in that it’s SpaceX calculations. So an example could be between 10000 years or 10000 seconds.
