Planet 9 from outer space

[Poppa Tom]

I was thinking about this and just wondered, "The EU would be put on the scientific map if, included within the gravimetric equations, the EU hypothesis is used and the exo planet is discovered. I think it should be much smaller than gravity predicts.

What or which exo planet?

What or which exo planet?

The infamous planet X, of course.
I do mean the planet that is affecting all the other planets orbits. Which is how they know one is out there. I just thought if it was a giant brown dwarf or another large planet, it just may have a magnetic field that would be detectable? Postulating.

Hi Poppa Tom,
Okay, I see what you mean, Planet X.
You are confusing two separate things. An exo planet is a planet orbiting another star. For example if a planet were discovered to be orbiting Alpha Centauri then it would be an "exo planet." By contrast, Planet X is a yet to be discovered planet orbiting our Sun, that is within our solar system.

What or which exo planet?

My, uneducated theory is:
If the imaginary magnetic fieldlines of the sun could be 'tracked' and the solar systems planets lay along them(?) then, by extrapolation, an estimation could be made as to where ANY exo-planet may be from Mercury to the end of the suns magnetospere. The orbit of them anyway.
Thanks for taking the time to educate me and answer my questions. I appreciate it. I understand I don't understand.

I get it, exo planet IS NOT what I meant to say, thanks
