Piercing the Earth

+0
−0

How much force, momentum, and energy would be needed to have an object pierce through the Earth? I've tried to research this, but I could not find results for a mathematical value.

Assume the Earths density is uniform, with the average density of the actual Earth, and that the object piercing the Earth is a sphere with a radius of 1 meter made of an indestructible material. Would it be possible to find mathematical values (force, momentum, energy) for such an event? Thank you for any help.
