Does venus have an iron core
WebVenus and Earth have similar radii and estimated bulk compositions, and both have an iron core that is at least partially liquid. However, despite these similarities, Venus lacks an appreciable dipolar magnetic field. Here I examine the hypothesis that this absence is due to Venus's also lacking plate tectonics for the past 0.5 b.y.
