Shattering a planet

[TheUnshakableOne]

How would you calc the shattering of a planet through means of a physical strike instead of an explosion? The planet was shattered into large fragments. Though half the planet still remains but it has deep cracks through it. The other large chunks were pushed a massive distance out as well.

Would you use the same equation and formula as an explosion calc, or would a different calc be necessary?

For reference this is the feat

If a planet is destroyed via an explosion, you don't calc the explosion. Assuming the Gravitational Binding Energy of the Planet was bypassed, Kinetic Energy is used for Planet destroying feats. If the GBE isn't bypassed, it's just baseline Planetary. If in this case, half the planet shattered and exploded out far, calculate the planet's kinetic energy using half its mass.

Thank you I'll try that
