Planetary Magnetic Fields: Venus
Recall that in many ways, Venus is
Earth’s twin:
- Venus has a radius 95% that of
the Earth
- Venus has a mass 82% that of
the Earth
- Venus has a density 96% that of
the Earth
One might
expect Earth and Venus to have similar magnetic field properties.
Why would I
say that?
But are mass,
density and radius all that determine whether a planet has a magnetic field?
