The brightest, most massive and most luminous object among those 131 is Sirius A, which is also the brightest star in Earth's night sky; its white dwarf companion Sirius B is the hottest object among them. The 10 Closest Stars to Earth - ThoughtCo.
Without the Sun, life would not exist here on Earth. It lies 8.5 light-minutes away from Earth, which translates to 149 million kilometers (93 million miles). Similarly, the closest star to the Sun, Proxima Centauri is marked with a red circle, close to the bright stars Alpha Centauri A and B. 10 closest stars to earth | BBC Sky at Night Magazine.

The Closest Stars to Earth (Besides the Sun). Discovered in 1915 by Scottish astronomer Robert Innes, Proxima Centauri has remained hidden from human eyes for millennia, despite being the closest star. Its low brightness—about 0.17% the luminosity of the Sun—makes it invisible to the naked eye, even on the clearest nights. How Do We Know How Far Away the Stars Are? 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. Walking to Proxima Centauri would take 950 million years. Equally important, if you turned it up and went as fast as Apollo 11 went to the Moon, it would still take 43,000 years.
