Sorry Marshal, I meant to write 99.89372. That's much more sophisticated.
Right, so how did you get this number?
I made it up. See, first I took the orbital data of Mercury, Venus, Earth, Luna, Mars, Deimos Phobos, Ceres, Jupiter, Io, Europa, Ganymede, Callisto, Saturn, Titan, Uranus, Neptune, Triton, and Pluto for the period of one year. Then I selected 53 of the most well-known artificial satellites in Earth Orbit, including the Hubble and the ISS. I then compared each set of orbital observational data with what would be predicted by Newton's equations.
The result was so far over 99.99% that I figured you wouldn't believe me, so I picked a number that was really large, but realistically off, using a bit of psychology. All very scientific.
