Besides our own star, the next closest star is Proxima Centauri (one of 3 stars orbiting each other) about 4.2 light years from earth. Therefore the light from that star takes 4.2 years to reach us (unfortunately, Proxima Centauri is too faint to be seen with the naked eye. Its larger orbital partner that can be seen is Alpha Centauri which is about 4.3 light years away).

the closest celeb is Proxima Centauri, greater advantageous than 4 easy years away - so, the easy we see coming from it left Proxima's floor greater then 4 years in the past. Sirius, between the brightest stars in our sky is approximately 8.a million easy years away - so, we are seeing it because it became 8 years in the past. And, it particularly is not distance that determines how far our eye can see, yet how bright something is. we can see (slightly) the bushy Andromeda Galaxy with our eye, and it particularly is greater the two.2 *million* easy years away. So, if something happens *suitable now* to a celebrity you're observing - we will not get the information of what befell till the easy from the form finally arrives here in the international.

Proxima Centauri
Its approximately 4.22 light years away, so the light takes 4.22 years to reach us, whereas the light from our sun takes approximately 8 minutes.

4.3 lightyears, a lightyear the distance that light travels in a year: 5,878,500,000,000 miles. That makes the next nearest sun about 271,800 times farther than the first nearest one.

I think it's about 6 or 7 light years. That would be 186,000 miles per second for 6 or 7 years. A long ways.
