Which physical feature of the planet Mercury causes the deflection of solar wind particles away from its surface?

Question

Quizplus · Accepted Answer

The deflection of solar wind particles away from Mercury's surface is caused by its magnetic field, which produces a magnetosphere. This magnetic field is not as strong as Earth's, but it is enough to deflect the charged particles of the solar wind away from the planet. Choices A and B are not correct because Mercury has a very thin atmosphere and no ionized stream of atoms. Choice D is not correct because while Mercury does have a gravitational field, it does not affect the behavior of solar wind particles.
