Sirius moved from star to star for 100,000 years

In this video, you can see Sirius moving slowly through the 100,000-year-old stars: where it was 50,000 years ago, where it is now, and where it will be 50,000 years from now. Sirius was one of the first stars to find itself in motion. In 1718, Edmund Halley examined Ptolemy's map. This is made possible by the relative proximity of Sirius to the sun. Before that, stars were thought of as static light.
