Actually a mechanical device clinging to an asteroid would take well over 100,000,000 million years travelling at a very rapid average speed to reach the nearest star which probably has no intelligent life even if it has orbiting planets.
Well yeah...was just pondering a possibility.

You are underestimating human race! In fact the fastest ever spacecraft (Helios-B?) was clocked at 240,000 km per second in 1970s. It would take no more than 22 thousand years to reach the closest star to Earth other than Sun which is Proxima Centaura at that speed.
