Disclaimer: I am not a physicist, or even the best at math. I just used logic and an estimation-based approach to devising a hit point count for sundering the Earth, distinctions will be made below.
So before the start of this, let's define a few things. For the long block of math, I defined "sundering the earth" as dealing sufficient damage to the mass to destroy the inner core, and cause the planet to crumble. Disintegrating the Earth completely would take a more precise, and much higher, number as you'd have to account for percents of the different materials that make up earth, rather than using an average of 9 hardness. By destroying the Inner Core, you prevent the Earth from having a sufficient mass to reintegrate into a full planet, and at best, you might get a belt of debris, and a series of planetoids.
The different layers of the planet are not thought to be perfect spheres, but these estimations account for the total mass of each layer evening out to about the described thickness if you were to line them up, for simplicity.
Some math to calc sufficient damage to sunder an Earth-Sized planet
So somebody math estimated about 17 bill
but that's under Dio's surface calc
Five sources
every answer is different
30 km-thick crust
Imma do my own answer
using Dio's crust calc
Alright so one way is to multiply Dio's calc of the Crust's HP by 100 and you get the result, as the crust roughly compromises 1% of the planet's matter
Or
Roughly the earth is 8130 km radially, making the circumference about 16260 km thick going through, not accoungin for the Inner Core's size
so the Inner Core has a radius of 1220 km on its own
2440 km + 16260 km
18700 km circumference
calculating the area off of this the Earth is 274645883.75845369938950044117475 sq.km
We'll round up to 274645884
So the crust represents about .3209 percent of the area, based on the earlier radial math
so we'll round that up to a third of a percent
23,665,910,400 is the amount that Dio estimated would take the crust off
So plugging that in to multiply it by 3, then by 100
7,099,773,120,000
round up to 7,100,000,000,000 to account for the lost .0191 percent in rounding
Sundering the Earth takes that many hitpoints
Of course, that's considered a "broad" sunder where the force of the attack disperses across the entire body and creates rubble, as if it were exploding from all points. An alternative is the damage needed to simply destroy the core of the planet, and force an atmospheric death via explosion, which would require roughly a third of this HP be dealt just to the dense core, and even then enough damage dealt to reach it, taking at least 100,000,000 damage, depending on the size of the attack you're attempting with, larger attacks needing more damage, while smaller ones have less material to break through.
