The moon is only 1/4 the size of the earth, and its gravity is only 1/6 of that on earth. This made the U.S. astronauts, during their moon walks, 5/6 lighter than they were on earth. A person who weighed 90 kg on earth would weigh only 15 kg on the moon. Because of this weak gravity pull, champion running high jumper Dwight Stones, who leaped 7′6 5/8″ on earth (at Munich, West Germany, 1973) would have leaped 45′3 3/4″ had he been on the moon.
