Nauru

Linguists guess that the word Nauru is from the Nauruan word Anaoeo which means "I go to the beach".

The whole country is just one island, the smallest in Oceania, and its 8.1 square miles or 21 square kilometers, the whole edge of the county is 12 miles or 19 kilometers long yes the WHOLE edge of it, meaning that you can take a jog in the morning all the way around the island and be back in time for lunch (what an exercise well now you can say I waked a whole country once).

Nauru is the ONLY country that doesn't have an official capital, most would say Yaren because that's where the parliament is, but it is only listed as a "main district" by the country, with 1.3k people living in Yaren it is the 3rd most populated part of Nauru, Arijejen in Aiwo with 2.4k people, and Menen in the Menen distinct with 1.4k.

For boats, it is nearly impossible, as the sharp coral reefs can pierce ships' hulls.

A road titled the "island ring road" which circulates the whole island, the Nauru Detention centers cooperate with Australia and are used for illegal immigrants, the centers are used as a containment area for immigrants illegally trying to get into Australia by sea, not only the normal population Nauru has a fluctuating amount of people in the detention center, the highest amount of illegal immigrants was about 1.2k in 2014, 

Nauru gets less than 1k people a year in tourists.

Nauru only is 34 miles or 56 kilometers away from the equator, Nauru sticks out as one of the 3 "great" phosphate (bird poop) rock islands, Guano droppings from migrating birds have made Nauru one of the richest in this limited recourse, they did have the highest GPA in the world when they opened up the mines for phosphate, after decades of mining the phosphate the GPA dropped a significant amount.

Nauru knew that the phosphate would run out eventually so they put trust funds, but the funds got mismanaged to the point that they almost went bankrupt, since the country is mainly a cash-only country so if you want to come here get your money first before boarding the plane, fishing, and the small amount crops, most goods come from Australia and New Zeland, most of the country either stocks up on non-perishables or others, Chinese, western, and spam fried rice are common here, this diet has made the World Health Organisation say the Most Obese in the world, as 70% of the country is obese, and 94% overweight.

The population of 11.2k people and it's the 3rd least populated country after Tuvalu and Vatican city, there are about 15k Nauruans globally, 8k live in USA and 1k live in Australia, which means that there are more Nauruans living abroad than in their country.

Australian dollar as currency (no surprise as they are nearby Australia).

The Nauruan navigational system is the only possible on Nauru, the armor of the Nauruans was coconuts and thick coconut fibers, and some still follow the Frigate bird fishing method for fishing.
