Any text you add should be original, not copied from other sources. Protons make up by far the largest part of the solar wind, and so it was previously thought that they had the strongest influence on the rock. An Introduction to Modern Astrophysics revised 2nd ed. Klasse No. The boundary of this region is called the magnetopause , and some of the particles are able to penetrate the magnetosphere through this region by partial reconnection of the magnetic field lines.

The solar wind can be strongly affected by solar flares and coronal mass ejections , both of which fling huge amounts of coronal material and embedded magnetic fields into space. Plage Spicule Moreton wave. The total number of particles carried away from the Sun by the solar wind is about 1. And no one knows why the corona gets so hot. The rules of orbital mechanics mean that requires a lot of energy. Blogs up icon. Metzler and M.
