Hubby is binge-watching a sci-fi TV show where aliens come to Earth for nefarious reasons. This triggered a thought cascade whereupon first I thought about interstellar travel, then planetary exploration, and then Star Trek©®™ (where the Federation had people go explore planets for various reasons), and finally I landed on the idea that planets are worlds, and worlds are really, really big regardless of the size of the planet. For example, a person can spend his or her entire life exploring just the United States and still not see everything worth seeing, and this is just one country out of nearly 200 of them on Planet Earth. How is someone supposed to explore this one planet, much less multiple of them in a lifetime?
But then I remembered that in the Star Trek©®™ universe they have transporter technology that allows them to travel from place to place virtually instantly. So for example, a person could beam up to an orbiting space station and then beam back down to the surface at another location. And in this way, a person could do a cursory exploration of a lot of places in a short time.
And this is where I got the idea of exploring Earth in just one year. The premise is that a person would start in one place, spend the day there checking things out, and then beam to a new place the next day. I thought, well, a person could visit every country on Earth and still have nearly half of the year left over. Of course, some countries are small and you could get a good idea of the place in just a day. But some countries are very large and varied, and it would be better to visit them more than once.
So, I came upon the idea of determining this. What countries would be visited more than once, and how many times would they be visited? I used an apportionment technique similar to what is done for the United States Congress. In that legislative body, each state receives at a minimum one representative, and then additional ones are assigned based on population until all 435 seats have been assigned, with the goal of having the number of people per representative as nearly equal as possible. Thus, I assigned 1 day to every country, and then apportioned the remainder until 365 days had been assigned, and doing this in a way that was as equitable as possible. I added in a visit to Antarctica for the 366th day, if it were a leap year. However, instead of basing these daily visits on population, I based in on a country’s land area excluding water. Now, there are valid reasons for exploring lakes and oceans, but from a cursory standpoint they’re mostly just water and aren’t much to look at. How hard is it to explore a level, featureless surface that stretches to the horizon? I started with the “Sporcle-recognized countries”, removed Kosovo since, well, there are reasons I won’t go into here, and then looked up each country’s land area in square kilometers (well, any unit will do, since it’s all relative) from Wikipedia, and then calculated the numbers.

The results showed each country had between 1 and 5 visits, except for six countries that had more than 12. Each country on this map is color-coded for the number of times you would visit that country in your Explore Earth In One Year program. For the six countries, their numbers are labeled on the map. Dependent territories are colored the same as their sovereign state, so just because an island somewhere is colored, doesn’t necessarily mean it gets its own visit. The United Kingdom, for example, qualifies for one visit, but it has territories scattered all over the planet. To which place will you go? Odds are it will be Great Britain and not Saint Helena.
One thing that surprised me was that I was expecting most countries to have one visit, with a few having several. I was surprised that Russia’s apportionment was as high as 28. And even such obscure countries as Central African Republic would be visited twice. Interestingly, even though nearly all of the countries of Europe are visited only once, you’d still spend more time on that continent than in mainland North America, where you would spend a little more than two weeks each in the United States and Canada. One would spend 86 days in Africa and another 114 days in Asia and 36 days in South America.
Have fun exploring!
