Question

What would have happen on earth if jupiter was as close as mars?

Answer 1

Mars is 225 million km away from the earth while Jupiter is 588 million km away. So while Jupiter is almost twice as close than it was

effects of this exchange of planets. Jupiter would obviously have a bigger gravitational impact on the Earth than it currently does. The Earth's orbit will change according to Jupiter's relative position to us, but only slightly. A bigger noticeable effect will only happen after a couple of millenniums.

Jupiter's magnetosphere extends to around 7 million kilometers. Though this is by far the largest in the solar system, it is still very small compared to the eventual distance of Jupiter from us at 225 million km. Of course, due to this reduction in distance from the sun, it's magnetosphere will also change.
