Some math about the satellite that orbited the Earth during
the Tiahuanaco calender time period.
Prior to Noah's flood around 9600 BC there were evidently
290 days in an Earth year. After Noah's flood it appears
there were 360 days in an Earth year till 701 BC. After 701
BC there were 365 and 1/4 days in an Earth year. It also
seems Mars used to pass very close to the Earth every
few years during this time.

According to the Tiahuanaco calender in Bolivia when it was made there were 290 days
in an Earth year. Also at that time there was a satellite orbiting the Earth a little
faster then the Earth rotates. So it was moving faster than a geosynchrous orbit. It
may have been composed of mostly ice. It may also have been smaller than our moon. A
geosyncherous orbit would put the center of the satellite around 43,623 km from the
center of the Earth.
Roche's Limit
Roche's Limit basically says when a large satellite gets to close to say a planet,
the gravity of the planet will pull the satellite into pieces. I read if the satellite
was greater then 200 miles in diameter it could be pulled apart by roche's limit. But I
haven't been able to verify that 200 mile number yet. So
how close can a satellite get to say the Earth before the gravity of the
Earth will pull it apart? First you take the density of the Earth which is 5513 kg/m3.
Divide that by the density of the satellite. The density of our moon is 3346 kg/m3.
Density of Mars is 3934 kg/m3. Density of Mimas a mostly icy satellite of Jupiter is
1100 kg/m3. Density of Titan another satellite of Jupiter is 1600 kg/m3. Density of an
satellite made entirely of ice would probably be 920 kg/m3. So let's divide 5513 by 920.
We get 5.99. Now we need to determine the cube root of 5.99 by calculator to get 1.816.
Now take 1.816 times the radius of the Earth which is 6378 km to get 11,582 km. Lastly
take 11582 times 2.44 for a Fluid Satellite to get 28,260 km. Or take 11582 times 1.26
for a Rigid Satellite to get 14,593 km. It seems an icy satellite would be tore apart
by Earth's gravity when it's center was between around 28,260 km and 14,593 km from the
Earth's Center. Of course, this does not include variables like the satellite's tensile
strength.
Mimas, a satellite of Jupiter, with a density of 1100 kg/m3 would be tore apart when it
was between 26,612 and 13,745 km away from the Earth. Titan with a density of 1600 would
be tore apart when it was between 23,505 and 12,138 km away from the Earth. The moon with
a density of 3346 would be pulled apart between 18,381 and 9,492 km away from the Earth.
The sites I've looked at all say around 9,500 km. So it appears satellites like the moon
and Mars are considered Rigid for this exercise. However, it seems an icy satellite would
be considered more liquid. Mars density is 3934. It's destruction would occur between 17,415
and 8,993 km away from the Earth.
