Abstract
The solar planets orbit the Sun with velocities less than the velocity of an electron orbiting a proton in the fifth level of energy in hydrogen atom, while if a body B takes place at the hydrogen surface of the sun, this supposed body will orbit the Sun with the same velocity of this electron according to the gravitational law GM(s)/R-s with which we calculate the orbital velocity of any planet. The velocities of solar planets from Mercury to Pluto, therefore follow that of B, each according to its distance from the Sun's center. The Sun which is a hydrogen star therefore behaves as a large hydrogen atom with number of 'constant' levels of energy, the mentioned velocities being obtained from gravitational law means the disappearance of the borders between gravity and electromagnetism as gravity itself creates the electromagnetic bonds in the structure of the Sun where at its hydrogen surface the electron is at its fifth and last level of energy with its mentioned orbital velocity.
