Because of the large angle between the magnetic axis of Uranus and its rotation axis, its magnetosphere wobbles considerably as the planet rotates. Astronomers use this wobble to determine the
A) strength of the magnetic field.
B) interior rotation speed of the planet.
C) rotation speed of the atmosphere.
D) density of the planet.

Question

Quizplus · Accepted Answer

The wobble of Uranus's magnetosphere, caused by the large angle between its magnetic axis and rotation axis, provides astronomers with information on the interior rotation speed of the planet. This is because the magnetosphere's behavior is directly influenced by the planet's internal dynamics, including how fast it rotates internally.
