Apollo lunar-module astronauts stood side by side only 16 inches apart, viewing the lunar surface through two two-square-foot windows.
Notes on verification
Window size and side-by-side standing arrangement confirmed by NASA/Grumman technical documentation and Smithsonian sources. The specific '16 inches apart' figure is only found in the original Smithsonian article and not independently corroborated elsewhere, though it is plausible given known LM cabin dimensions.
