Some rapid-fire U.S. state trivia

The first official U.S. state was Delaware, which was the first colony to ratify the U.S. Constitution in 1787. Pennsylvania, New Jersey, Georgia, and Connecticut followed. The most recent U.S. states to be admitted were Alaska, which joined the U.S. in January 1959, and Hawaii, which followed suit in August 1959.
Each state acquired its name differently. Many took their names from Indigenous words, such as Connecticut, which takes its name from the Mohegan word Quinnehtukqut, meaning “upon the long tidal river.”
Every state has its own unique nickname, many of which reference well-known landmarks, crops, or other defining aspects of the state. Just 14 states’ nicknames have been adopted in state legislation.
The largest U.S. state is Alaska, which spans 665,384 square miles. Texas is second-largest, at 268,596 square miles. The smallest is Rhode Island, which measures just 1,545 square miles. Meanwhile, the most populous state in America is California, which is home to some 39 million people—more than the 21 least populous states combined. The state with the lowest population is Wyoming, which has just around 576,851 people.
The U.S. state that borders the fewest states is Maine, while Tennessee and Missouri are tied as the states that border the most states; each shares a border with eight other states. The state with the longest coastline is Alaska, which has a longer coastline than all other 49 states put together.
