Anonymous Coward User ID: 88145 United States 09/24/2007 03:19 PM Report Abusive Post Report Copyright Violation | I have discussed this question with several people claiming the earth's axis has tilted several degrees. No one can refute my claim, so... Quoting: Anonymous Coward 302765The earth has a series of geostationary satellites in orbit around the equator. The speed of the satellites match the rotational speed of the earth so they appear to remain in the same place/plane in the sky. If the axis of the earth has tilted, would not these satellites now be out of alignment EXCEPT at two points along the equator? In other words, with an axis tilt the new orbit of the satellites would place half of them above the new equator and the other half below the equator. Since there has been no such dislocation of the geostationary satellites (all are still in communication) this would prove there has been NO axis shift of the earth. And NO, an axis tilt would not "drag" the satellites into the new orbital plane. Would any of you pushing "the earth's axis has shifted" please let me know where I've gone wrong here? You are right...satellites orbit around the center of mass of teh earth. If the earth's tilt changed, the satellites would continue on their track and would appear out of place on the surface. Likewise, Polaris would no longer be at an altitude equal to your latitude, and no GOTO telescope on earth could function. Anyone pushing that the earth's tilt has changed is simply ignorant of these easy ways to verify that it hasn't. |

Do you ask why some satellites are in different orbits as opposed to being in a ring around the equator? If so, this has to do with the angle at which the lift vehicle is launched in reference to the equator. Has nothing to do with gravity or 'orbit rings'. |
