Australia Is Wider Than the Moon

It’s a surprising realization that the continent of Australia, from its easternmost point at Cape Byron to Steep Point on its west coast, spans a greater distance than the diameter of the Moon. The width of Australia is roughly 4,000 kilometers, while the Moon's diameter is approximately 3,474 kilometers. This means that if you were to place the Moon over a map of Australia, the continent would extend out on either side. This comparison highlights the immense scale of Australia, a single country that is also a continent.

This geographical fun fact often catches people by surprise due to the way our planet is typically depicted on maps. The most common world map, the Mercator projection, was designed in the 16th century for navigational purposes. A significant drawback of this projection is that it distorts the size of landmasses, making areas farther from the equator appear much larger than they actually are. Because Australia is situated closer to the equator, it appears smaller in comparison to landmasses in the Northern Hemisphere, which are stretched and exaggerated.

While Australia may be wider than the Moon's diameter, it is important to remember that the Moon is a sphere and Australia is a landmass on a much larger sphere, Earth. Therefore, in terms of total surface area, the Moon is significantly larger than Australia. The Moon's surface area is about 38 million square kilometers, whereas Australia's is approximately 7.7 million square kilometers. This makes the initial comparison a fascinating, though specific, measure of size.
