Once an object is in space, such as a satellite, it is very easy to rotate or move using very little force. In fact such little force is required to manipulate, a ten ton object, The Hubble Telescope for example; that an astronaut can literally rotate it with their finger.

Given the above statement, 1Newton at 102grams per second (approximately), is a force that effects the rotational axis of a ten ton object in space.

The total estimated weight of the Earth in space is 0kg. The total estimated mass is a different story, 6600 trillion tons or 5.98741928 × 10^21 grams.

The total number of Newtons required to effect the Earth in a similar way to a satellite is given by dividing the total mass of the Earth (grams) by 1N (102grams)per second. 5.8700189 × 10^20 Newtons per second

Now to further extrapolate this theory the Space Shuttle will be used calculate the total number of Newtons it has exerted during it's history before entering space.

Stats for Space Shuttle:

134 Flights, April 12th 1981 - May 16th 2011.

8 Minutes to reach orbit (480 seconds). Solid Rockets x2, 120s. 3 main engines 480s.

Solid rocket thrust 12.5MN each, (37 500 000) Newtons per second.

Main Engine thrust 5.45MN each (16 350 000) Newtons per second.

Therefore the total number of newtons exerted for the Space Shuttle over it's entire history is: 1 056 132 000 000

or 1.056132 x 10^12N

Given the above calculations are correct it would require 555 803 526 times the History of the Space Shuttle to have the same effect on the Earth as an astronaut exerting 1N of force per second on a orbital satellite with a mass of 20 Tons!

I am not able to find data on the total number of objects leaving the earth and entering orbit, but the total number of satellites in orbit are approximately 3000. Those are the approximate current operational satellites.

As to what kind of force it would require to move the Earth a millionth of the force applied by the proposed astronaut? Given the calculations presented it is evident that we have effected the Earths rotational axis.

Feedback please....

(I would like to thank all the cows in the world and their flatulence for providing me with this theory)
