Hi mihael,
The following are the calculation that caused wrong results:
9.8 m/s2
In the first equation above, g is referred to as the acceleration of gravity. Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2.

How do you calculate the acceleration of gravity?
Calculate the acceleration due to gravity on the surface of the Earth. The mass of the Earth is 5.979 * 10^24 kg and the average radius of the Earth is 6.376 * 10^6 m. Plugging that into the formula, we end up with 9.8 m/s^2. Calculate the acceleration due to gravity on the surface of the Moon.

The Principia, published in 1687, argued that a unified system of scientific principles governed what happened on Earth and in the heavens.
In Proposition Eight, Newton tried to demonstrate the correctness of his explanation by calculating the mass, surface gravity and density of the known planets. To determine the mass, he needed to know the angle between a line from the center of the Earth to the Sun, and a line from a point on Earth to the Sun. Routine Class Assignment
Modern science has put that number at about 8.8 seconds. (A second is one-3,600th of a degree.) Newton believed the figure to be 10.5 seconds, but he mysteriously used 11 seconds in the equation. That is the error Mr. Garisto (student) discovered when he repeated those calculations as part of a routine class assignment.

So the point is in school they still teaching Newton's gravity law at 9.8m|s2.
