Pioneer 10 included a plaque, shown above. Pictographically, it shows humans, where we are, and where we come from. Just in case anyone should ever find it and get curious. At the bottom is a representation of the Solar System to help identify home…with nine planets.
That highlighted planet is Pluto. Now that they demoted Pluto, the aliens will never be able to find us.
