It is worth noting that I am not 100% sure on the 5th nearest miss. The distance I measured for Honduras was 1,409km, Nicaragua was 1,417km, and Costa Rica was 1,418km. I am pretty confident the Costa Rica number is correct, but the other two are hard to measure because there are a bunch of tiny islands off the coast, and it is hard to figure out on Google Maps where the islands actually are, and what is actually land.
