How many years would it take to get to another galaxy?
To get to the closest galaxy to ours, the Canis Major Dwarf, at Voyager’s speed, it would take approximately 749,000,000 years to travel the distance of 25,000 light years! If we could travel at the speed of light, it would still take 25,000 years!
How long would it take light to travel to another galaxy?
Other Galaxies
| Object | Time for the Light to Reach Us |
|---|---|
| Sirius (brightest star in our sky) | 9 years |
| Betelgeuse (bright star) | 430 years |
| Orion Nebula | 1500 years |
| Andromeda Galaxy | 2.5 million years |
How many light years would it take to leave the galaxy?
So, to leave our Galaxy, we would have to travel about 500 light-years vertically, or about 25,000 light-years away from the galactic centre. We’d need to go much further to escape the ‘halo’ of diffuse gas, old stars and globular clusters that surrounds the Milky Way’s stellar disk.
How long would it take to travel to the closest galaxy?
Thank you for you greatly, appreciated, time. The closest galaxy is the recently discovered Canis Major dwarf galaxy, which is “only” 25,000 light-years away. So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that’s the amount of time it would take from the perspective of the outside world.
How long would it take a star to cross the Milky Way?
It Would Take 200,000 Years at Light Speed to Cross the Milky Way. (One light-year is the distance light travels in a year, about 6 trillion miles or 10 trillion kilometers.) To put the find in perspective with the location of our own sun, astronomers said the newly found disk stars are about three times farther from the galaxy center than the sun.
How long would it take to travel at the speed of light?
So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that’s the amount of time it would take from the perspective of the outside world. From the perspective of a traveler moving at the speed of light, it would appear to take no time at all.
How many light-years across is the Milky Way?
Past studies have suggested the Milky Way is between 100,000 light-years and 160,000 light-years across. (One light-year is the distance light travels in a year, about 6 trillion miles or 10 trillion kilometers.) To put the find in perspective with the location of our own sun,…
