Detailed explanation-1: -The closest star to us is actually our very own Sun at 93, 000, 000 miles (150, 000, 000 km). The next closest star is Proxima Centauri. It lies at a distance of about 4.3 light-years or about 25, 300, 000, 000, 000 miles (about 39, 900, 000, 000, 000 kilometers).
Detailed explanation-2: -Proxima Centauri, the closest star to our own, is still 40, 208, 000, 000, 000 km away. (Or about 268, 770 AU.)
Detailed explanation-3: -The closest star, Proxima Centauri, is 4.24 light-years away. A light-year is 9.44 trillion km, or 5.88 trillion miles. That is an incredibly large distance.
