One starts with a high accuracy value for the position (x, y, z) and the velocity (v x, v y, v z) for each of the bodies involved. When also the mass of each body is known, the acceleration (a x, a y, a z) can be calculated from Newton's Law of Gravitation. Each body attracts each other body, the total acceleration being the sum of all these ...
This means that the acceleration vector ¨ of any planet obeying Kepler's first and second law satisfies the inverse square law ¨ = ^ where = is a constant, and ^ is the unit vector pointing from the Sun towards the planet, and is the distance between the planet and the Sun. Since mean motion = where is the period, according to Kepler's third ...
An elliptic Kepler orbit with an eccentricity of 0.7, a parabolic Kepler orbit and a hyperbolic Kepler orbit with an eccentricity of 1.3. The distance to the focal point is a function of the polar angle relative to the horizontal line as given by the equation ()
The traditional orbital elements are the six Keplerian elements, after Johannes Kepler and his laws of planetary motion. When viewed from an inertial frame, two orbiting bodies trace out distinct trajectories. Each of these trajectories has its focus at the common center of mass. When viewed from a non-inertial frame centered on one of the ...
He showed that, for each planet, there is a distance such that moons closer to the planet than that distance maintain an almost constant orbital inclination with respect to the planet's equator (with an orbital precession mostly due to the tidal influence of the planet), whereas moons farther away maintain an almost constant orbital inclination ...
The motion of these objects is usually calculated from Newton's laws of motion and the law of universal gravitation. Orbital mechanics is a core discipline within space-mission design and control. Celestial mechanics treats more broadly the orbital dynamics of systems under the influence of gravity , including both spacecraft and natural ...

The TOP2013 solution is the best for the motion over the time interval −4000...+8000. Its precision is of a few 0.1″ for the four planets, i.e. a gain of a factor between 1.5 and 15, depending on the planet, compared to VSOP2013. The precision of the theory of Pluto remains valid up to the time span from 0 to +4000. [9]
