用法筆記
Frequently used with the possessive form of a planet's name (Earth's magnetosphere, Jupiter's magnetosphere) to specify which planet's magnetic region is being discussed. In scientific contexts, 'magnetosphere' applies to any planet with a strong enough internal magnetic field — Mercury, Earth, Jupiter, Saturn, Uranus, and Neptune all have one.
