Planet orbit

An observer on a planet referential knows that he describes an elliptic orbit around the sun, which occupies the A position in the perihelion focus. The sun emits photons in all directions. The one that will reach the planet on the x position will go through its AX trajectory in a time t, with velocity c.

Planet’s orbit seen by an observer in the absolute space

The real planet’s orbit has a helicoidal form, with a very long step in relation to the medium ray of the curve.
