How long would it take a spaceship to get to Andromeda?
How long would it take to get to the Andromeda Galaxy? Forget it! Although it may be one of the closest galaxies to our own, since the Andromeda Galaxy is 2.5 million light years distant it would take 2.5 million years to get there if (and it’s a huge ‘if’) we could travel at the speed of light.
How long will it take for the Andromeda Galaxy to collide with ours?
about 4.5 billion years
The Andromeda–Milky Way collision is a galactic collision predicted to occur in about 4.5 billion years between the two largest galaxies in the Local Group—the Milky Way (which contains the Solar System and Earth) and the Andromeda Galaxy.
How long does it take light from the Andromeda Galaxy to reach Earth?
2.5 million years
The Andromeda (pronounced An drah’ mid a) Galaxy lies about 2 1/2 million light years from Earth….Other Galaxies.
| Object | Time for the Light to Reach Us |
|---|---|
| Andromeda Galaxy | 2.5 million years |
How fast is Andromeda Travelling towards us?
110 kilometers per second
Based on Doppler shifting of its light, Andromeda is speeding toward us at 68 miles per second (110 kilometers per second). Compare this to the light from Andromeda, which is moving toward us at 186,000 miles per second (300,000 km/s).
How many kilometers away is the Andromeda Galaxy?
| Andromeda Galaxy | |

How long would it take to reach the end of the Milky Way?
The disk of our home galaxy – the Milky Way – is bigger than we previously thought. A new study shows it would take 200,000 years for a spaceship traveling at the speed of light to go across the entire galaxy.
How long is Andromeda at light speed?
Here are their distances from us: Large Magellanic Cloud – 179 thousand light years away Small Magellanic Cloud – 210 thousand light-years away Andromeda Galaxy – 2.9 million light-years away One light year is the distance that light travels in one year in a vacuum at a speed of 186,000 miles per second or about …
How do you find the Andromeda Galaxy?
Most people find the galaxy by star-hopping from the constellation Cassiopeia the Queen, a very noticeable M- or W-shaped pattern on the sky’s dome. You can also find the Andromeda galaxy by star-hopping from the star Alpheratz in the Great Square of Pegasus. Both methods will lead you to the galaxy.
