I thought the accepted value for core radius (liquid + solid) was 3480 km
giving 6960 km across the thing. Maybe I misinterpreted that....
but,

>Surrounding this is the mantle, 8 to 50

I hope I read that wrong. There's over 200 km of mantle just between the
~410 and ~670 km discontinuities.......
