But what forces are causing this to occur? Eccentricity is a measurement of how much the conic section deviates from being circular. This means that it is a measurement of how much the orbit (in this case) deviates from the 0 or the center. When a satellite orbits the Earth in moves through an atmosphere depending on the satellite, when this occurs it can begin to venture inwards or outwards of the orbit due to Earth`s seasons and direction change creating a fluctuation in the amount eccentricity the
This help them to balance, and stay in the orbit. The acting point between planets which stay in an orbit and the sun is the orbit. Also, the calculation of the orbit is that “The orbit is an ellipse with an eccentricity of about 0.017, so the distance to the sun at any given day would be: r = a(1-e*e)/(1+e cos(theta)).” (researchgate.net). There are eight planets in the orbit in total (there is another planet, but it doesn’t count as the planet in the orbit anymore). “The total mass of all eight planets is around 2.67 x 1027 kg.

In theoretical need shows that a 10 km tether would be required to lower orbit altitude by 100 km. This method tethers infeasible due to the increased collision hazard presented by the large tether
Since the Earth’s orbit is an ellipse, not a circle, its distance from the sun varies from a minimum of 147.1 million kilometers each January to a maximum of about 152.1 million kilometers each July. The range of this distance has little effect on Earth’s weather with the Northern Hemisphere’s summer occurring during the time that Earth is
Time after time, science and technology have proven that we live on a spherical planet. Now that we have access to space, the easiest way to prove the Earth is a sphere is to leave it and view it from a distance. Astronauts and space probes have done just that. Every picture of Earth ever taken shows only a circular shape, and the only geometric solid which looks like a circle from any direction is a sphere. The horizon is the surface that one is observing from is not an infinite plane.
It travels 254 miles from the earth and it takes approximately 2 days to fly to the International Space Station. It travels at 4.75 miles per second. The max speed of the station is 17,500 miles per hour. It takes 1.5 hours {92 minutes} to orbit the whole earth. The Station has a pressurized volume of about 32,333 cubic feet.
It is larger than the Earth, although its color has brightened and faded the spot has been for at least 162.5 years. The GRS rotates counter-clockwise with about six Earth says or fourteen Jupiter day. Its dimension is about 24,000 - 40,000 km east to west and 12,000 – 14,000 km north to south. The spot is big enough to hold two to three Earth size planet. Infrared data has indicated that the GRS is colder and higher in altitude.
A radio signal can only travel in a straight line however. Enter the satellite. By placing an orbiting satellite at 37,000 km (22,300 miles) above the earth and having it match the earth's rotational speed (7,000 miles per hour) the satellite stays over the same spot above the earth. This is referred to as being in geosyncronous orbit. These orbits are sometimes also referred to as Clarke orbits in honor of Arthur C. Clarke who first came up with the idea in an article he wrote back in 1945 entitled "Extraterrestrial Relays" published in Wireless World Magazine.
While the solar system is in alignment for a brief moment in time, each planet would have to rely on the balance of its neighbours to maintain stability. Humans are ignorant to these calculations, we have never met any other neighbours as we only deal with humans on the planet. We are ignorant to the others in the solar system. Each planet is comprised of unique substances, gases and materials, which would make their existence, or life experience look quite different from ours. The one calculation that is consistent is that the mass of the earth would need to be only as heavy as the gravity of the moon and the energy of the sun were strong enough to suspend the weight to keep the earth stable.
