Is Sedna responsible for the magnetic polarity switch of earth?

Question

almost incrementally documented, is a series of world wide deluges that have kicked ancient civilizations into the depths of the oceans. Harbinger's Glaciation states are directly linked to Electro-magnetic activity, but is it extra-terrestrial?

Answer 1

Sedna- we dont not know enough about this dwarf planet just yet. And for now, it is too far away.
==========================================
"Sedna" will become closer and brighter over the next 72 years before it begins its 10,500-year trip to the far reaches of the solar system and back again. "The last time "Sedna" was this close to the Sun, Earth was just coming out of the last ice age; the next time it comes back, the world might again be a completely different place,"
============================================

I think the accepted theories are still mostly tectonic plate movements for all the deluges. Some scientists have proposed meteor hits. Its probably both.

Are you asking if Sedna is extra terrestrial? What about Quaoar?

Scientists Discover Record Fifth Planet Orbiting Nearby Star

11.06.07

PASADENA, Calif. - Astronomers have announced the discovery of a fifth planet circling 55 Cancri, a star beyond our solar system. The star now holds the record for number of confirmed extrasolar planets orbiting in a planetary system.

55 Cancri is located 41 light-years away in the constellation Cancer and has nearly the same mass and age as our sun. It is easily visible with binoculars. Researchers discovered the fifth planet using the Doppler technique, in which a planet's gravitational tug is detected by the wobble it produces in the parent star. NASA and the National Science Foundation funded the research.
==================
And there will be more discoveries.
