Question

which is the nearest sun from earth?

Answer 1

The sun that gives us heat and light for our daily life to survive on the Earth is the nearest sun from earth.

Answer 2

The simple answer is that the Sun is the closest star to Earth, about 93 million miles away, but that might not answer your question. Outside of our Sun, our system's nearest neighbor is Alpha Centauri. This isn't a single star, it's actually a triple-star system — three stars bound together by gravity.
