Latitudes
The latitudes of Copenhagen, Edinburgh, Glasgow, and and Moscow are very similar,
Copenhagen: 55.7° N
Edinburgh: 55.9° N
Glasgow: 55.86°N
Moscow: 55.8° N.
I wonder what the attraction of this latitude is? Is it geography? Is it the balance of daylight hours? Is it coincidence - after all there are endless places that are not at this latitude.
Still...
One degree of latitude is 111 km (about 69 miles) on average.
The exact distance varies because the Earth is not an exact circular ball. So the distance between latitudes at the equator are about 110.6 km, and at the poles they are about 111.7 km
