what is the closest star outside of our solar system？
Proxima Centauri, the closest star to our own, is still 40,208,000,000,000 km away. (Or about 268,770 AU.)2020年12月8日
Then,What is the next nearest star system to our own?
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).
In this way,Can we reach Proxima Centauri?
It's still only 21 light-hours distant, in contrast to Proxima's distance of more than 4 light-years. Using Voyager 1 technology, it would take us 80,000 years to travel to Proxima Centauri.
Subsequently,How far away is the closest star beyond our solar system?
The closest system is Alpha Centauri, with Proxima Centauri as the closest star in that system, at 4.25 light-years from Earth. The brightest among these systems, as well as the brightest in Earth's night sky, is Sirius.
Beside above,Which stars are outside the solar system?
There are 5,017 known exoplanets, or planets outside the Solar System that orbit a star, as of May 1, 2022; only a small fraction of these are located in the vicinity of the Solar System....Exoplanets within 10 parsecs.

about 5.9 trillion milesA light-year is the distance light travels in one year. How far is that? Multiply the number of seconds in one year by the number of miles or kilometers that light travels in one second, and there you have it: one light-year. It's about 5.9 trillion miles (9.5 trillion km).
Voyager 1 is expected to keep its current suite of science instruments on through 2021. Voyager 2 is expected to keep its current suite of science instruments on through 2020.

“None of the physically conceivable warp drives can accelerate to speeds faster than light,” Bobrick says. That is because you would require matter capable of being ejected at speeds faster than light—but no known particles can travel that fast.

Alpha CentauriAlpha Centauri is one of the brightest stars in the southern skies and is the nearest stellar system to our Solar System — only 4.3 light-years away.
The third star in the Alpha Centauri system, Proxima Centauri, is actually the closest star to our solar system at approximately 4.2 lightyears away from Earth.
