A total of 12 astronauts walked on the moon during the Apollo missions, from 1969 to 1972. Each Apollo mission had a team of astronauts, with two astronauts landing and walking on the moon's surface during each mission.
The Apollo missions had different crew sizes, with the majority of missions having a crew of three astronauts. However, the first two Apollo missions (Apollo 7 and Apollo 9) were crewed by three astronauts, while Apollo 8 and Apollo 10 had crews of four. Apollo 11, which famously landed on the moon, had a crew of three.
The number of astronauts varied in each Apollo mission. For Apollo 7, 8, 9, 10, and 11, there were three astronauts. For Apollo 12, 14, 15, 16, and 17, there were four astronauts. Apollo 13 had initially planned for three astronauts, but one was replaced due to illness.
