    Moving the Moon closer would make a great space station and vacation spot.

    Until it broke up and then rained on the Earth for hundreds of years.

    And the stepladder suggestion seems to presuppose that the Moon is
    both very close to the Earth and yet stationary relative to the Earth,
    which might be harder to achieve then just contracting the orbit.

    which might be harder to achieve then just contracting the orbit.

    The Earth-Moon Roche limit is 9600 km, center to center, or about 2000
    km surface to surface.

    Any closer, and the moon would break up.

    At that height, the moon would orbit in about five and a half hours.

    Effects on the tides would be noticeable, about 1600x larger than now.

    So, the stepladder suggestion (in the popup in the online comic) is
    definitely out, then.

    Or do it from a small boat like they used to have in the
    old days - "The Distance of the Moon" by Italo Calvino,
    found in the collection Cosmicomics (highly recommended).
