What's Inside Venus?

Venus is a little smaller than the Earth, but is probably like the Earth inside. Venus is made of rock and metal, and probably has a partly melted metal core, a rocky mantle, and a crust. The planet rotates very slowly, taking more than 243 Earth days to spin once on it's axis. This may be why the planet doesn't have a magnetic field like many of the other planets, including Earth.
