It Is what we commonly call a "fixed" star, but It moves apparently about an inch a century. Even that microscopical microscop-ical movement, to be calculable at such an Immense distance, means a speed of 1,900,000 miles a day. The light by which, tonight, one may easily see Sirius left that star 30 years ago.
