what is the closest solar system to us？

The closest star to Earth is a triple-star system called Alpha Centauri. The two main stars are Alpha Centauri A and Alpha Centauri B, which form a binary pair.2021年11月5日

Keeping this in consideration,What is the closest solar system to our planet?

Proxima Centauri is the closest star to the Solar System and is orbited by the planet Proxima b.

Correspondingly,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.

Similarly,Can we 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.

Thereof,Will Voyager 1 ever stop?

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.

### Can humans ever travel at the speed of light?

Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. According to Albert Einstein's theory of special relativity, summarized by the famous equation E=mc2, the speed of light (c) is something like a cosmic speed limit that cannot be surpassed.

### How long would it take to travel 4.2 light-years?

about 6,300 yearsProxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology.

### What planet could we live on?

Then, just last year, scientists discovered another Earth-like planet orbiting one of our closest neighboring stars, Proxima Centauri. Currently, this planet is the best candidate we have for supporting human life.

### How long will it take to fly to Mars?

The trip to Mars will take about seven months and about 300 million miles (480 million kilometers). During that journey, engineers have several opportunities to adjust the spacecraft's flight path, to make sure its speed and direction are best for arrival at Jezero Crater on Mars.

### Will humans ever reach another star?

The nearest star is 4 light years away. That means that light, traveling at 300,000 kilometers per second would still need 4 YEARS to reach the nearest star. The fastest spacecraft ever launched by humans would need tens of thousands of years to make that trip. But science fiction encourages us to think it's possible.

### Will humans ever travel to another galaxy?

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.

### Could life exist on the Sun?

The Sun could not harbor life as we know it because of its extreme temperatures and radiation. Yet life on Earth is only possible because of the Sun's light and energy.
