1/5,163,600 of a light-year
So (assuming constant velocity) it would have taken approximately 21,887 years for an object traveling at 130,000 mph to reach Earth from Proxima Centauri (closest star at 4.24 light years).
Proxima doesn’t strike many as a likely candidate for life, so it would probably would have had to be sent sometime when the dinosaurs ruled the Earth.
It’s moving 1.9 percent the velocity of light.
