How Long Will It Take To Walk Around The Moon?

February 14, 2024

If you're able to walk at the maximum speed of your ability for 4 hours each day, it'll take you nearly 1.5 years to walk around the Moon, which has a circumference of 10,921 kilometers or 6,786 miles. However, according to Aidan Cowley, a scientific consultant at the European Space Agency, humans will not have the technology or equipment needed for such a journey until at least the late 2030s or 2040s.

In reality, walking on the Moon will be much slower than this due to factors like low gravity, clunky space suits, and the need to move around obstacles such as craters. Furthermore, walking on the Moon requires a large supply of food, water, and oxygen, which you'll need to carry with you. All of this adds up, and even when factoring in rest breaks, it will still be a very challenging journey.

To get a more accurate estimate, Cowley used the results of a NASA experiment in which eight participants were put on treadmills inside aircraft that were flown on parabolic trajectories to simulate lunar gravity. The participants were able to achieve speeds up to 3.1 mph (5 km/h), which is more than double the speed managed by the Apollo astronauts on the surface of the Moon, despite their clunky suits. The high speed was possible because the participants were able to swing their arms, similar to how people run on Earth, creating a pendulum motion that partially compensates for the lack of gravity.
