the furthest distance from Earth that a human has traveled to and returned safely is the Moon. The Apollo missions, specifically Apollo 11 to 17 from 1969 to 1972, allowed a total of 12 astronauts to land on the Moon's surface and return to Earth. The farthest point reached by these missions was during Apollo 17, which reached the Taurus-Littrow valley on the Moon's surface. The Moon is approximately 384,400 kilometers (238,900 miles) away from Earth.
Since my knowledge is not up-to-date, it's important to note that future missions or advancements in space travel could change this record. There may be plans or ongoing missions aiming to reach greater distances, such as crewed missions to Mars in the future. It is always worth checking the latest space exploration news and updates for the most current information on human travel in space.
