Sirius, continued

In my previous post about Sirius, I forgot to mention that it is one of our nearest neighbors in the galaxy. In fact, after our own sun, Sirius is the fifth nearest star to Earth, 8.6 light years away. That’s one reason it is so bright.

If you were an extraterrestrial living in the Sirius system, you would, of course, see our Sun in your night sky. Despite the relatively short distance, our Sun would not be as prominent as Sirius is for us. Sure, it would be visible to the naked eye, but it would only be about as bright as the North Star (Polaris) is to us. The Sun would look like a pretty ordinary star, except that billions of people would be looking back at them.

Here is a chart of the nearest stars to Earth, most of which are not visible to the naked eye.
