1.Till now high ranked conservative astronomers (the bigest part of all) supposed, that there not exists bigger body (planet, moon sized) on extreme elliptic path in our solar system, that this is not even possible. On my web page mujweb.cz/spolecnost/bode
I gave arguments that it is possible.

2. Directions of main half axes, inclination of Sedna's orbit's plane is nearly identical with X. Orbital time is within X's and Nemesis's.

3. Compare position of X from Senmut's map and from my oriental carpet with Sedna's. it is the same area of sky you fools, dear anti X's....

4. Orbital time of Sedna is according JPL around 10000 years, but this is only estimation, because JPL don't count orbit of Sedna in case that very heavy X (1/40 of Sun's mass) is here quite close.

5. I think that Sedna could be something like Troyans toward Jupiter. It share the same or nearly the same path with X during one or more orbits...
