[DS2] Moon Stats (was: Moon - Help Requested)

This one I can't help you with.

Your stats are in error re: the Moon's mass. Your individual *weight*
on the moon is ~1/6 that on Earth, but this does not correspond directly
to the Moon massing 1/6 that of Earth. It's more like 1/8. Here are some
stats:

The Moon:

  Mass: 	       734.9x10(**20) (+/- 0.7) kg
  Relative Mass:       123x10(**-2)  or  0.123003 Mass(Earth)
  Density	       3.34x10(**3) kg m(-3)
  Relative Density:    0.59045 Density(Earth)
  Radius:	       1738 km

>From here it's relatively straightforward to calculate the
circumference.	:)

Depending on your scale, I don't think the moon's limiting horizon would
limit *that* much compared to range of weapons...but ymmv.
