“Loneliest Human,” the latest edition of xkcd’s what if?
What is the furthest one human being has ever been from every other living person?
It’s hard to know for sure!
The most likely suspects are the six Apollo command module pilots who stayed in lunar orbit during a Moon landing: Mike Collins, Dick Gordon, Stu Roosa, Al Worden, Ken Mattingly, and Ron Evans.
Each of these astronauts stayed alone in the command module while two other astronauts landed on the Moon. At the highest point in their orbit, they were about 3,585 kilometers from their fellow astronauts.
