It is unlikely that you will want to take a walk around the world on the surface of the Earth’s satellite after you see these numbers.
The answer to this question depends on many factors, including how fast you can walk, how much time each day you spend walking, and which path you take to avoid falling into craters. Such a journey around the moon could take more than a year, but to complete it, many problems must be solved.
During the Apollo missions, astronauts jumped on the surface at a speed of 2.2 km/h, according to NASA. This low speed was mainly due to the clumsiness of the suits, which did not allow for high mobility. If the astronauts wore smarter suits, they might be able to move much more easily and move faster.
A study published in 2014 showed that the maximum walking speed on the Moon is about 5 km/h. After reaching this value, a person already begins to run.
At this new hypothetical maximum speed, it would take approximately 91 days to travel 10,921 km around the circumference of the Moon. If it were possible to walk on the surface of the Earth in the same way without stopping, then the entire journey would take 334 days.
Obviously, it’s impossible to walk non-stop for 91 days, so the actual walk around the moon would take much longer. If you walk on the surface of the moon for 4 hours a day, skirting the craters, it will take, according to calculations, more than 500 days, or about a year and a half.
