Mars N = 1.10 6 m -3 v = 330km s -1 T = 200 K n = 3.10 10 m -3 r 0 = 155-175 km above the ground (i.e. it is so small it could reach the surface. (R M = 3393 km) OTHER PLANETS WITH MAGNETOSPHERES: the GAS GIANTS The Jovian system Once we get out beyond the asteroids we are back again to planets which have magnetospheres, like the Earth. Jupiter, indeed, has an enormous magnetosphere because of the very strong magnetic field it possesses. It can be interesting to "compare and contrast" its magnetosphere with that of Earth: The stand-off distance up-wind is around 100R J , which is much greater than the Sun's radius, making Jupiter and its magnetosphere the largest object in the solar system. The tail goes out beyond Saturn's orbit. The very strong Jovian nd Saturn's orbit. The very strong Jovian B field is
