Reposting this from the "Jupiter" thread. because although Mars does not belong in the Mercury-Venus-Earth OP limitation, it has the same elements, arguments and results. There is a relationship between the rotation, revolution and the planet size, that is unique, showing in zero or related conditions, aka the imaginary space drag.
Mars:
Orbital velocity 86652 km/hr
Radius: 3397km
Equatorial rotation velocity 868 km/hr. therefor:
3.91 km of radius for I km of equatorial speed.
86652 : 3.91 = 22161 km.--OV-RV =0 because they oppose in direction at noon. (like on Jupiter.)
Zero velocity, OV-RV=0 at 22 161 km
Moon Deimos orbit radius: 23 458 km a match within 6%. so :
This is the 5 st zero velocity area match based on the radius of planet size / velocities in the ecliptic.
The extended rotational speed of Mars projected out ward to match the orbital speed, gives the orbit of Deimos (5)
