No. The radius of a circle inscribed in a equilateral triangle inscribed
in another circle is half of the big circle, so the moon is too small.
If you inscribe a tetrahedron in the sphere, you get a smaller inscribed
sphere with a third of it's radius, which is still too large.
I think this nicely shows why one should mistrust pictures purporting
to show the secret relationships in nature - one has to check the
numbers, otherwise it is easy to be fooled.
