orA Comparison of the Magnetospheres

between Jupiter and Earth

Superlatives of Jupiter:•Most massive planet in the solar system.

•Rotates the fastest.

•The strongest magnetic field.

•The most massive satellite system of any planet.

•The Magnetosphere of Jupiter: Coupling the equator to the poles

Factors needed to form and maintain magnetosphere:

• A strong enough planetary magnetic field that halts the solar wind.

• A source of plasma internal or external to the magnetopause to populate it.

• A source of energy to power it.
