View Full Version : Jupiter's Odd Magnetic Field Question.

According to this article Jupiter's magnetic field is very peculiar.


With the lines both connecting north and south AND north and an area just south of its equator.

Couldn't this have been caused by Jupiter swallowing a planet sized body with a large iron core?

If Jupiter had a second core generating this, wouldn't it have to be in orbit of the center? It would shed an awful lot of orbital energy into the soup surrounding it, this would not be a long-term situation before it joined the core. It would heat up Jupiter, might cause inexplicable large scale atmospheric structures, but ultimately signs of its existence would fade when it fully merged.

My knowledge of the matter of planetary core mergers is they are seldom, if ever, complete.

I was told in class even Earth's core isn't perfect, even after billions of years of merging with Thea.
