Deviation of sun for an observer in absolute space

In the figure, the sun located on A point of its trajectory, in the absolute space, displaces to A_n position with expansion velocity in universe b. The sun is always in the perihelion of the elliptic orbit of the planet. If we project orthogonally the A point on the orbit P_n plane, this projection will occur in the maximum axle of the orbit, on the B_n point, so that Bn is in a distance D from A_n.

In a time t:
- The sun goes from A position to A_n;
- Its projection on the plane P_n goes from B_n position to A_n position, with velocity V, where V is the projection of velocity b.
The sun’s trajectory AA_n creates an angle with the the biggest semi-axle of the ellipse.
