Then supposing that the earth does weigh relatively the same, how does it effect the rotation of the earth, orbit of the earth when we do remove weight from our sphere by sending things into space?
Also, the rotation of the Earth has been slowing throughout its history. The first days were only 6.5 hours!

Did the fast spinning Earth have a ring around it when it was very young?
When the Earth was very young, its faster rotation caused it to have a much larger equatorial circumference than it has at the present time. It may have been spinning fast enough to have a "Saturn type ring" around it.
It is well known that the rotation of planet Earth is gradually slowing. For four and one half billion years, its entire lifetime, its rate of rotation has been gradually slowing. As the Earth loses its kinetic energy due to all forms of friction acting on it; tides, galactic space dust, solar wind, space weather, geomagnetic storms, etc., like any flywheel, it will slow down. (The space surrounding the planet is far from empty).
...over the course of the planet's entire lifetime, it has had very profound effects on the geophysics of the planet.
It has caused mountains to rise, earthquakes, etc. to occur as we will see. This article is about, factoring in the tremendous geophysical activity that was caused, by the Earth's slowing rotation, in the interior of the planet, its crust, oceans and atmosphere over its entire lifetime.
Tracing these tiny milliseconds back for 4.5 billion years adds up to a very significant amount of time for a solar day. I have determined that the day/night rotation was 63,000 seconds shorter than the present 86,400 seconds it is today. This would put the Earth's rotation at about 6.5 hours per day/night cycle, when it was created, 4.5 billion years ago. (This is a much faster rate of rotation than the Cassini-Huygens mission (2003 to 2004) determined Saturn's 10.5 hours rotation period to be.)
