    Does the moon control the sun through magnetisms?

    No, it doesn't.

    The moon is on the order of 1/6 the mass of the earth, the sun is something like 38,000 times the mass of the Earth. While everything in the universe effects everything else, the moon's effect on the sun is minimal.

    Correction, the moon is on the order of 1/81 the mass of the Earth.

    Methinks the confusion was over local gravitational acceleration on the moon being 1/6 of that on the Earth.

    Also, the moon's magnetic field is a tiny fraction of the Earth's (at least 3 orders of magnitude less) and not even a dipole, just a varying field over the surface. And I assume the Sun's magnetic field is even larger still.

    So, no.

    Yes, thanks, but that merely makes the point greater. Thinking the moon controls the sun is like planning on pulling an ocean liner with a canoe.
