How far in the past are you looking when you see the closest star?
Alpha Centauri, the nearest star visible to the unaided eye, is at a distance 270,000 times the distance between Earth and the Sun. That’s 4 light years, so we see Alpha Centauri as it was 4 years ago. Some bright stars are much more distant still. Betelgeuse, in the constellation Orion, is about 640 light years away.
