水星的固有磁场很小，再加上它离太阳很近，使得赫米恩磁层在比较磁层研究的背景下是独一无二的。赫尔墨斯磁层的基本结构被认为与地球相同。然而，存在着各种各样的差异，这些差异导致了地球上没有的新的、令人兴奋的效应出现。这些新的影响可能会迫使我们对naïve关于水星磁层的预测进行实质性的修正。在这里，我们根据我们在地球上的经验概述了预测，以及哪些影响会彻底改变这一图景。磁层的基本结构很可能通过缩放地球的情况来理解，但它的动力学方面很可能被Hermean磁层的小和来自地球表面的大量重离子所显著改变。
The small intrinsic magnetic field of Mercury together with its proximity to the Sun makes the Hermean magnetosphere unique in the context of comparative magnetosphere study. The basic framework of the Hermean magnetosphere is believed to be the same as that of Earth. However, there exist various differences which cause new and exciting effects not present at Earth to appear. These new effects may force a substantial correction of our naïve predictions concerning the magnetosphere of Mercury. Here, we outline the predictions based on our experience at Earth and what effects can drastically change this picture. The basic structure of the magnetosphere is likely to be understood by scaling the Earth’s case but its dynamic aspect is likely modified significantly by the smallness of the Hermean magnetosphere and the substantial presence of heavy ions coming from the planet’s surface.
