COMMENTS

If we plot these numbers, we get something close to a normal distribution. If we look at the graph more closely, it may be construed as two bell curves: (1) Mercury, Venus, Earth, Mars; (2) Jupiter, Saturn, Uranus, Neptune, Pluto.
There are many ways in which this sequence is unsatisfactory. The status of Pluto as a planet is now in doubt. The true values are unlikely to be integers. The use of miles rather than kilometers is deprecated.  N. J. A. Sloane, Sep 28 2006
