Now some basic rules. We will assume that both Earth and Sun are made only of concrete. Now onto the fun stuff.

Earths volume in cubic centimetres = 1.08321*10^27 Centimetres. Subatomic destruction of concrete is about 996 tons of TNT per CC
So 996 X 1.08321e+27 = Tons of tnt. Thats quite a big number.In joules 4.513146911999999e+40
So it comes to Small Star Level. Impressive.

Here comes the sun (I love that song)
It's volume is about 1,4123*10^33 Centimetres Soooo.
996 X 14212300000000000000000000000000000 = 1.4155451e+37 TONS of TNT now in Joules = 5.922640698399999e+46
So thats Solar System right there.
