Magnetosphere questions

  1. Jan 6, 2008 #1
    Hi, I don't have a solid background in astrophysics. I need some help.
    Jupiter's magnetosphere is elongated by the Sun.
    It almost reaches the orbit of Saturn.
    What would happen if, by increased solar output, the magnetospheres touched?
    Recently we had a conjunction of Jupiter and Saturn. Could that cause the earthquakes?
    How does the red eye on Jupiter connect with Sun ?
    Is it affected by the sun and jupiter, (Was there a reaction when sun peaked of 2001)?
    Could the solar fields contain a reaction on a gas giants surface and "ignite" it?
    It would be really nice if you could point me to research.
    Thanks in advance.

    See if these help.

    Here is a summary of Jupiter's magnetosphere, which apparently goes out as far as Saturn, and that would imply that that the two magnetospheres have touched as Jupiter by-passes Saturn.




    On earth? Using g = GM/r2, one could compare g's for M = mass of moon, Jupiter and Saturn at closest approach to see the relative gravitational effects.

    Relation between the Visibility of Jupiter's Red Spot and Solar Activity

    If one means fusion reactions, the answer is no. There are interactions between atmospheres of the planets and the solar wind, and no ignition takes places.

    I think the spots on both sun and jupiter are created by opposing fields.
    Maybe all gas giants and stars are positive "poles" and black holes the negative.

    Is it possible for gas giants to fuse? Could that make our solar system binary?
    Thanks for caring.

    That's an interesting idea, but I believe that the red spot on Jupiter is present even in quiet solar period without sunspots or the massive eruptions. The red spot on Jupiter is certainly a unique feature as planets go.

    AFAIK, black holes are far away, so they wouldn't have much influence on us.

    System 2M1207 is interesting.

    For a second star in our system, Jupiter would have to pick significant mass - about 80 times its present mass in hydrogen to become a star.
    Here is an interesting discussion on Jupiter and the Galileo spacecraft which crashed into Jupiter - http://www.badastronomy.com/bad/misc/jupiter_galileo.html - it also talks about what would need to happen for Jupiter to become a star.

    It is unlikely that Jupiter and Saturn would collide. They are pretty much set in their orbits.
