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
