Closest star is Alpha Proxima. Approx. 4 light years away. Ummm, it wouldn't help if the sun went out.
Alpha Proxima, but don't think it will matter, all life on earth will end pronto.
It shines as brightly because of the distance it has from earth and it has to do with how old the star is.
As Neptune is not a star the question is unnecessary - the Sun is the nearest star to the Earth. After that the next star is Alpha Proxima.
The sun is a star, the closest one to Earth. The next nearest star to Earth is about 265,000 times farther away than the sun is.
No. The sun is the closest star. The next closest star is Proxima Centauri

Proxima Centauri and even sun( sun is also a star)

The Sun, which is a fairly ordinary star, is the closest star to Earth. I presume that's not what you meant. The next closest is Proxima Centauri, a dwarf star 4.2 light years from our system, and its much brighter companion Alpha Centauri is next closest.
