Celestial motion refers to the original power of celestial motion formed in the inner space after BIGBANG, that is, the source point of power, which is actually the most basic source of material motion, and the formation of gravitational field composed of cosmic original power materials is the birth of electric field and magnetic field.

After the birth of magnetic field and electric field, a centrifugal force and repulsive force field of celestial motion will be formed. Under the action of BIGBANG, we can see different celestial galaxy clusters, including a considerable number of star systems and other planets. Under the original power, the celestial body will rotate and revolve.

Basic formula of physical celestial motion

1, Kepler's third law: t2/r3 = k (= 4π 2/gm) {r: orbital radius, t: period, k: constant (independent of the mass of the planet, depending on the mass of the central celestial body)}.

2, the law of gravity: f = GMM/R 2 (m, m is the mass of two objects. Just like finding the gravity between the earth and the sun, where m is the mass of the sun and m is the mass of the earth.

3. Gravity and gravity acceleration on celestial bodies: GMM/R2 = mg; G = GM/R2 {r: celestial radius (m), m: celestial mass (kg)}.

4. Orbital velocity, angular velocity and period of the satellite: v = (GM/R)1/2; ω=(GM/R3) 1/2； T = 2π (R3/GM) 1/2 {m: mass of central celestial body}.
