The Planet "X " Theoretical Calculation of The mean Orbital Velocity & Orbital Period

By use this equation's formula and use the Earth values as constant we can get the Theoretical Calculation of ( mean orbital velocity& orbital period ) for The Planet " X" and all planets of solar system' in theoretical mode..

Caltech researchers have found evidence of a giant planet They nicknamed " Planet Nine" tracing a bizarre, highly elongated orbit in the outer solar system. It has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune, which orbits the sun at an average distance of 2.8 billion miles. This new planet would take between 10,000 and 20,000 years to make only one full orbit around the sun. The planets move around the sun in elliptical orbits, these orbits are not perfectly circular, but appear on both ends of buckling a little so that it looks oval. The orbits of the planets are not all elliptical; as the planet Mercury ,Venus and Pluto have circular orbits, while the other planets in the solar system have elliptical orbits, nevertheless close to the circular orbit,  The proportion of buckling in the orbit of the planet Earth does not increase from 0.0034 moreover the orbit of the planet Mars in 0.0052 while splays of the proportion of the highest in the orbit of the planet Saturn, where the rate is 0.1076. During the rotation of the planet in its orbit, we find that there are two positions one of them the planet will be closer to the sun and the other position is far from the sun, planet's speed variations in its rotation around the sun depending on its position, the planet's speed will be high value when the planet is close to the sun.

In this paper focus on The Planet "X" moreover use the Earth values as constant to calculate all values of Solar system planets.
