Well Orcot, I did a breif search for a totally gold solar bodie as you requested, I thought it would also make a good target for some to look at to define so accruracy measurements, something that would give a good signiture. A very good suggestion thank you. So in the search i found a lot of gold, none of them so far are 50% gold, I have been to Uranus,Neptune and Jupiter just doing spot checks for gold, it seems that if a soild gold lunar bodie (or a lunar bodie that surface crust is made of gold) is to exist it will have to be in the orbit of Saturn, i have not checked Saturn as of yet, and to mention I have only did a random check. ( this is not done by computer so it takes time)
In addition i have to make a correction appearantly i have mixed up several lines in the list for ganymede and so the list for ganymede got posted different to two times, the below is the orginal list for ganymede and the correct one. several things posted change as a result, such as the amount of gold and other element abundances posted.
Kaneda , The rarest element on ganymede become Ytterbium. As for Lutetium it Comprises 5,796,456.3 cubic miles of ganymedes compostion, a considerable increase being about the surface area of Antartica. Lutetium has a normal layer placementabout 3.64 miles below the surface. Ganymede has a surface area of 28,067,407.65 square miles and so it seems that Lutetium will be present on the surface,however
it is a rather heavy element and so may be parceled to the interior.
As well Phosphours becomes the most abundant element on ganymede in the correction, the white streaks on ganymedes surface are likly Potassium as potassium comprises 11.4% of ganymede for 1,604,468,601 cubic miles. and has a normaized layer 186 miles below the surface.
From the center of ganymede to the near surface, the following list is the compostion of ganymede exstending the radius. Florine is the center where Zinc is near the surface.
576.88 miles Florine
140.98 miles Neon
93.420 miles Sodium
181.02 miles Magnesium
7.6100 miles Aluminium
20.000 miles Silicon
198.93 miles Phosphourus
14.630 miles Sulfur
27.000 miles Clorine
47.800 miles Argon
71.200 miles Potassium
32.500 miles Calcium
1.0000 miles Scandinium
5.0000 miles Titanium
6.5000 miles Vanadium
10.500 miles Chromium
2.2500 miles Manegnese
0.4000 miles Ferrum (iron
0.3000 miles Cobalt
10.480 miles Nickel
3.4000 miles Copper
15.900 miles Zinc
All other atomic elements exist in the remaining 26.7 miles of the surface of Ganymede.
It would appear that ganymede is a rather heavy moon, as well that ganymede is soild from its surface untill a depth of 234.37 miles where the soild nature of ganymede is interrupted by a layer 27 miles thick of Argon, most likly any terrestial motion is due to the disturbance of the Argon layer.
Ganymede has a radius of 1,494.886364 miles, a total of 764.86 miles of that radius is composed of gases, with the remaining half 730.02 miles being composed of solids (as known on earth). This distribution seem to present ganymede as not only a heavy moon but also a subject of interest in balanced motion.
For some reason i was unable to go back and re-edit the first page, I guess i will have to give my eyes a little rest and save myself some typing and retyping.
