Earth ejecta are hypothesized meteorites or meteoroids which have been ejected from the gravity well of the planet Earth following the impact of a bolide and have escaped to outer space. These objects may or may not have have subsequently impacted another planet or moon. No examples of Earth ejecta have been discovered in outer space or on the surface of other celestial bodies. Mathematical models, however, have suggested that the amount of Earth ejecta that now exists elsewhere in the Solar System is greater than amount of meteoroids produced from impacts on all other planets and moons in the Solar System combined. It has been argued that Earth ejecta might be a means for life forms on earth to travel to other planets via panspermia processes.
