Nearest capitals

Distances are great-circle distances between city centres, which is what the Capitals game measures when it tells you how far a guess was from the answer. Buenos Aires is the closest capital to Santiago.

How to remember it

Reading a figure once rarely fixes it in memory. Attach Santiago to a place and a number you already know: it is 1,139 km from Buenos Aires, and it is the 24th largest capital in the atlas. Then practise retrieving it. DailyGeo Capitals gives you one mystery capital a day with distance, direction, language and population clues, the memorising method explains the review schedule, and the capitals index lists all 172.

To see how Chile compares with every other country on figures like these, the most expensive Big Mac index ranks them on geopolitix, a country-ranking game by the same maker as DailyGeo.
