what is the closest solar system to our solar system？
Alpha Centauri is a gravitationally bound system of the closest stars and exoplanets to our Solar System at 4.37 light-years (1.34 parsecs) from the Sun. The name is Latinized from α Centauri, and abbreviated Alpha Cen or α Cen.
Similarly,What is the next closest solar system?
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. They are about 4.35 light-years from Earth, according to NASA.
Accordingly,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.
Furthermore,How far away is Voyager 1 in light years?
A light-year is 9.5 trillion kilometers. By division, that means it's going to take Voyager 17,720 years to travel ONE light year. That's 80,000 years to reach Alpha Centauri, 4.5 light years away.
Beside above,How far away is Proxima d?
Proxima d is one of the lightest exoplanets found to date, at only about 1/4 of Earth's mass. The newly found planet orbits close to its star, at a distance of approximately 4 million kilometers (2.5 million miles).
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.
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.
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 Kepler space telescope identified the exoplanet, and its discovery was announced by NASA on 23 July 2015. The planet is about 1,800 light-years (550 pc) away from the Solar System....Kepler-452b.

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.
Physical characteristics. Kepler-22b is an extrasolar planet orbiting around the star Kepler-22. It is about 620 light-years (190 pc) from Earth in the constellation of Cygnus. It was discovered by the Kepler Space Telescope in December 2011.
Coe et al. For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km).
Outside mythology, no human has ever attempted to travel to the Sun. The main reason is fairly obvious—it's too hot. Even in a well-protected spacecraft, you could only get within about 2 million kilometres (1,300,000 mi) before burning up.
