what is the closest star system to 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
In this regard,What is the next closest star to our solar system?
Proxima CentauriThe 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).
Considering this,What is the closest system to the solar system?
At a distance of 4.25 light years, Proxima is the closest-known star to our solar system.

Then,How long would it take us to get to Alpha Centauri?
To get there in anywhere close to a human lifetime, spacecraft will need to travel a substantial fraction of light-speed—10% would get a craft to Alpha Centauri in 44 years. Achieving such phenomenal speeds would require equally eye-watering amounts of energy, even for a relatively lightweight probe.
One may also ask,Can humans live on Alpha Centauri?
So before even diving into the specifics of the system or its planets, no, humans can not yet go to Alpha Centauri and live there because, simply put, we wouldn't survive the trip. The Alpha Centauri system actually has three stars.
Distance Information Proxima Centauri, the closest star to our own, is still 40,208,000,000,000 km away. (Or about 268,770 AU.)
Season 1. The astronaut family of Dr. John Robinson, accompanied by a pilot and a robot, set out in the year 1997 from an overpopulated Earth in the spaceship Jupiter 2 to travel to a planet circling the star Alpha Centauri. The Jupiter 2 mission is sabotaged by Dr.
The technology required to travel between galaxies is far beyond humanity's present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
about 6,300 yearsLast year, astronomers raised the possibility that our nearest neighbor, Proxima Centauri, has several potentially habitable exoplanets that could fit the bill. Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology.
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.
Proxima b is a 1.3 Earth mass planet orbiting its star at about 1/20th of the Sun-Earth distance, which places it well within the so-called Habitable (Goldilocks) Zone.
Alpha Centauri B has no known planets: planet Bb, purportedly discovered in 2012, was found to be an artifact, and a separate transiting planet has yet to be confirmed....Alpha Centauri.
