So, during a game the question came up: "How much health does the earth have?" Anyone else ask anything like this before?

Yes. Long story short:
16,586,000,000,000,000,000 hp.

Thank you this helps.

I had a text file with an explanation of hardness per inch and volume of rock and other such things, but I deleted it by accident while deleting faulty antivirus software.

It has effectively infinite health. Because of gravity, no matter how many times you punch the earth, it will just re-form.

To actually destroy a planet, you have to hit it so hard that you accelerate every bit of it to escape velocity. This would take roughly 1,000,000,000,000,000 nukes going off at the same time.

It's a plot device. It doesn't have any because you can't hurt it.

Or what about 1 nuke with a yotta-ton yield?

...What.
Okay, now I've GOT to hear the story on this one.

Can't find it. But I found something kinda cool. VVVV

I googled, and saw 1 thread which gave no actual answer. Well, I want to apply some very "back of the envelope" calculations to get an overestimate. Feel free to refine on the estimate. (I'm assuming that the hit points of the earth can be calculated by looking at it's "thickness")

Let's pretend pi = 3.
Let's pretend the earth is made of solid iron (hardness 10, hp 30/inch).
Let's pretend the circumference of the earth is exactly 27000 miles (it's less).

The circumference of an object = pi x diameter.

27000 = 3 x Diameter.
27000/3 = 9000 miles in diameter.

9000*5280= 47520000 feet.
47520000 * 12 = 570240000 inches.
570240000 * 30 = 17,107,200,000 hit points.

At the very least, this means you would need to deal around 17 billion damage to go through the earth (if it were made of solid iron). So, a rough estimate of the earth's hit points is 17 billion. At least from some calculations I made.

Another possible calculation.

Maybe it would be better to just calculate it by the hit points of a 1 foot cube of iron and then extrapolate that outwards. A big tree has 600 hp. If we assumed a 1 foot cube of iron had 1000 hp and we made a big cube with sides of 10000 miles each...

10000*5280 = 52800000 feet on each side.
52800000^3 ~= 1.5e+23 = 150,000,000,000,000,000,000,000 cubes.
150,000,000,000,000,000,000,000 * 1000 hp = 150,000,000,000,000,000,000,000,000 hp.

Probably a way overestimate (since I basically packed the entire hit points of a very big tree almost twice into a 1 foot cube of iron (wood has 10 hp/inch vs 30 hp/inch)). 150 septillion hitpoints.

In 5e, I believe a "sturdy" Large object (up to 10' cubed) has 4d10 (22) hit points. For larger objects, you divide it into however many 10' cubic sections and each has 22 hit points. I'm gonna round that to 3 meters cubed.

The earth has a volume of roughly 1 trillion cubic kilometers, or 1e21 cubic meters. For every 27 of those cubic meters, it has 22 hit points.

So that's 22/27 * 10^21, or 8.1 * 10^20 hit points.

Where are you going to find one of those?

At the center of what is now the ultimate power in the galaxy.
I suggest we use it.

how much health does the sun has

Average density of the Earth is 5.5 g/cm^3, give or take. Density of iron is 7.87 g/cm^3. So we can probably use that to get a better estimate.

However much it has, it's clearly a Tiefling - it has Hellish Rebuke

Alright, I'm drunk enough to see if I can improve that.
>Given average density of the Earth is 5.51 g/cm3
>Given average density of steel is 8.05 g/cm3
I'd rate the Earth at average hardness 8, HP 20.5/inch using that.
>570240000 * 20.5 = 11,689,920,000 or about 11.7 billion hp.
HOWEVER
>Earth's diameter is 7,917.5 mi
>7917.5*63360 = 501652800 inches thick
>501652800*20.5 = 10,283,882,400 hp.
So 10 billion HP, give or take a couple of hundred million.
Let's see if we can get a hit dice estimate.
Assuming we're using d8 hit dice, we get 9 hp for every 2d8.
>10,283,882,400/9 = 1142653600 *2 = 2285307200d8, ignoring any Constitution/whatever bonuses.

>How much health does the earth have?
Very little left.

>He doesnt know about starfish prime

lolwut

Source is in the filename.

Yeah, I figured that one out.

Still there's a lot of "wut" to go with that manga.

According to Immortals' handbook an Earth sized planet has around 122,880HP.

I rolled to pin a plane of existence from a distance with a rope, while standing in another plane to destroy both in a god killing game once.

so, "what is the fall damage for heaven" took on a new meaning.

This is completely unhelpful, but:
Using d6 hit dice, we get 7 hp for every 2d6.
Conveniently, a goblin has 2d6 hp (in 5e, at least).
>10,283,882,400/7 = 1,469,126,057.14
Consequently, the Earth has about the same health as approximately a billion and a half goblins, give or take a bit.

>Let's pretend pi = 3.
REEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

That's damage that covers the entire planet at once right? Because if not then farmers and miners would kill their own planet in a day.

Who the fuck actually uses this shit in an actual pen and paper game with other humans? I knew 3.fags were autists of the highest caliber but who the fuck can take this shit seriously? Who was this written for?

>dude, I'm not tpking you with an impossible fight, look it has stats, maybe you shouldn't use the wishes I give you for broken stuff :^)

Yep, sounds about right.

Let me guess, you were playing rifts and players just started shooting the ground?

Or, you could be a clay golem and punch the earth over and over.

We were trying out the stranger aeons book for pathfinder, I'm not exactly sure how the question came up though.

Dont forget to add in the damage reduction factor or anything of its equivalent as well as resistances and immunities.

Or a ragnarok.

I fucking love that game, titans is my shit. When I'm done with SC2 ladder I jump on there, turtle up and arty spam with the fucking continent sized cannons. Not effective at all but it's a lot of fun.

Dude think about it, it's close enough. It's approximately a 0.05% difference to drop the decimal.

You have no idea

Yeah, let's use a Wyrmling Nexus Dragon, the Great Wyrm is obviously overkill.
