To put it into context, the closest distance between Earth and Mars is 33.9 million miles, and distance between Earth and Moon is only 238,900 miles.

This checks out. Closest theoretical approaches:

    >>> "%e" % (Pluto.orbit.periapsis - Earth.orbit.apoapsis)
    '4.272109e+12'
    >>> "%e" % (Mars.orbit.periapsis - Earth.orbit.apoapsis)
    '5.455552e+10'
    >>> "%e" % (Moon.orbit.periapsis)
    '3.631042e+08'
    >>> "%e" % Earth.radius
    '6.371000e+06'

Earth-Pluto: 4.27 Tm = 4.27e9 km = 2.65e9 miles

Earth-Mars: 54.6 Gm = 54.6e6 km = 33.9e6 miles

Earth-Moon: 363 Mm = 363e3 km = 226e3 miles

Earth radius: 6.37 Mm = 6.37e3 km = 3.96e3 miles
