How many miles is it to the nearest galaxy?
Well there's a simple question with a rather more complex answer.
The nearest galaxy is the Andromeda galaxy at about 2.5 million light years. Now it is just a unit conversion problem.
A light year is the distance light travels in a year .... about 6 million, million miles (
So the nearest galaxy is roughly 15 000 000 000 000 000 000 miles (
A long way, but it will one day engulf our galaxy and shred it to bits. Sleep well ;)
