If you could travel at the speed of light how long would it take to travel form our solar system to the nearest star?

Answer 1

The nearest star (besides our sun) is 4.24 light-years from earth. This means that light emitted for this star takes 4.24 years to reach earth. Some stars are over millions of light-years away. The closest star is the sun. Beyond that is Proxima Centauri, at 4.24 light-years away. Alpha Centauri is at 4.37 light-years, and beyond that is Barnard's star at 5.97 light-years away.

4.24 light-years = roughly 24,925,000,000,000 miles (rounded to the nearest billion miles) lol

Answer 2

The nearest star to our solar system is Proxima Centauri, located about 4.24 light-years away. If you were to travel at the speed of light, it would take approximately 4.24 years to reach Proxima Centauri.

Answer 3

There is a binary pair of stars called Alpha Centauri A and Alpha Centauri B. The third star, called Proxima Centauri, which may or may not be part of this star system, is about 4.22 light-years from Earth. Proxima Centauri is the closest star to earth after the sun.

Answer 4

The nearest start beyond the sun is Proxima Centauri which is approximately 4.2 light years (about 24,689,699,202,000 miles) away away from Earth.

Proxima Centauri is one of three stars in the Alpha Centauri system.

Answer 5

Alpha Centauri That star is the closest to any planet or dwarf planet in the solar system.

Alpha Centauri had long been considered the closest other star, but it turns out that there is red dwarf star called Proxima Centauri which is fractionally closer. Alpha is a star much like our own Sun, and easily seen in the Southern Hemisphere. Proxima is, I believe, not visible without a telescope.

Answer 6

As is usual with this type of questions, that will depend on the speed. The nearest star system outside our Solar System is the Alpha Centauri system, at a distance of about 4.3 light-years; that means it will take light 4.3 years to get there. Currently, humans don't have the technology to get there even in a century or in a millennium.

Answer 7

It would depend on the speed of your spacecraft. A current generation spacecraft would take about 100,000 years to make it to the nearest star, Proxima Centauri.

But we know HOW to make faster spacecraft, and the design and engineering of a starship is well within our reach. Such a ship, powered by an Orion Nuclear Pulse Engine, could make it to the nearer stars in perhaps 100 years. it would carry a crew of perhaps 200, with their children and grandchildren completing the voyage. If we started now, the first such starship might be launched in 20 years.

At least in theory, we can begin the design of even faster craft, but the construction of such spacecraft would be dependent on many fundamental discoveries which are unpredictable. One concept would be a "ramscoop" designed to gather interstellar hydrogen for fuel. Physicist Robert Bussard outlined the basic principles; the remainder is probably more engineering than pure phsyics.

Answer 8

The closest one we know about is Proxima (also called Proxima Centauri or Alpha Centauri C), a red dwarf star at about 4.2 light-years distance. Late-M red dwarf stars are quite dim, and it's at least possible that there might be one even closer to us than Proxima which we haven't discovered yet (that is: if one exists, then it has almost certainly been photographed many times, but no one has ever noticed it individually as more than simply another spot on a photographic plate or bothered measuring its distance yet).

Answer 9

Aside from the Magellanic Clouds (small sibling galaxies to the Milky Way visible from the southern hemisphere) the closest galaxy to our own (the position of the Earth in the Milky was becomes irrelevant at these scales) is the Andromeda galaxy about two million (2 000 000) light-years away. So it would take about two million years to reach it. You can see the Andromeda galaxy with the unaided eye, it is the oldest thing you can see in the sky without a telescope. It looks like a soft faint blur.

Answer 10

Proxima Centauri is the nearest star and it's about 4.22 light years away. So it would take about 4.22 Earth years to get there at the speed of light, if that were possible.

According to the Theory of Relativity we could never actually reach the speed of light. But, if we travelled anywhere near that speed there would be time "time dilation" effects. That means the time measured to reach the star would not be 4.22 years for a person actually on the space craft.
