The photon between sun and a planet, non considering the orbital motion V of the planet, to an observer in the absolute space

Photos emitted by sun on A, the one that will arrive at a planet, on X position, is influenced by expansion velocity b in the universe
In a time t:

- The orbital plane of the planet goes from P position to P_n position; with velocity b;
- The photon goes from sun on the A position to the planet on the X_n position, with velocity c_e2, where c_e2 = b + c;
- The sun goes from A position in the focus 1 to the A_n position in the focus 1´, with velocity b;

- The sun’s projection in the perpendicular axle to the biggest axle of ellipse goes from A to B_n, on the orbital plane P_n with velocity V₁´ where V₁´ = b sen Â.
- The planet goes from X position to X_n with velocity b.
- To an observer on the planet, the photon goes from sun to its with velocity c.
- To an observer stopped in relation to velocity b, the photon will always be between sun and the planet, approaching to the planet with velocity c.
- The projections of both sun and planet in the orbital plane P_n, go from B_n to A_n and from X₁ position to X_n, respectively, with velocity V, where V = b cos Â.
- The projection of the photon in an orbital plane P_n goes from B_n to the planet on X_n with velocity c₂ where c₂ = V + c.
When the projection of the photon, originated from B_n, arrives at the planet, on the X_n position, due to velocity V, projection of the velocity b of the planet on the plane P_n, and also the aberration effect, modifies its velocity c₂ to c, where c = c₂ - V.
Then, we can conclude it:
In the orbit of a planet, a photon originate from B_n point located in the biggest axle of the ellipse and, when it arrives at a planet, it gives an impression that it came from the sun located on A_n point, which is a focus of perihelion of this orbit. The B_nA_nX_n triangle works as if, in a time t:
- The sun would be from B_n position to A_n, with velocity V.
- The photon would be from B_n position to X_n, with velocity c₂.
- To an observer on the planet, the photon, which came from the sun, would arrive at him with velocity c.
The B_n position will be determined by X position of the planet in the orbit so that, time t which the photon goes from the sun to the planet, with velocity c, will define the distance D between B_n and the sun, where D = t x V.

Since we have defined this triangle, we can observe that c₂ = V + c.

Will we call this ellipse, which has the sun in the focus of perihelion and its projection varying due to the position of the planet in its orbit, as ellipse of fotonóide. The photon will be emitted from B_n position in direction of a planet in its orbit and it will arrive at the planet which is coming from focus of perihelion of the ellipse of fotonoide, through the mathematic expression:
c₂ = V + c.
