How long does take light to reach our neighboring Galaxy

If you want to make a big trip, do that one. Light takes 2.6 million years to reach us from the Andromeda Galaxy, our neighbour. You can see right now this galaxy in the constellation Andromeda if you have good eyes, because it is very low. With binoculars, it is very visible.

This is the the most distant object that can be seen with the naked eye. The speed of light is not that of a snail! It is 300,000 km per second! To go to the moon it needs 1.3 second and go to Sun 8 minutes, but for our neighboring Galaxy 2.6 million years! Measure the difference and particularly the large gap that separates us.
