Can an asteroid be destroyed?

Question

Can asteroids be destroyed by really fast impacts, or could I airdrop one into Kerbin without a chute and have the asteroid survive (though I think the space agency would get a lawsuit for such reckless behavior)?

You can also destroy asteroids by sending them towards Kerbol, if the wiki is correct:

No known way of landing on Kerbol exists, even with all cheats enabled. The overheating effect quickly destroys parts before they can reach the surface. Interestingly, asteroids have a maximum temperature tolerance of 1038 so do not overheat even under these circumstances, but are instead destroyed at an altitude of -250 m, which shows in the end flight dialog as "crashed into the surface of the sun" or similar, rather than ever landing.

I also wouldn't be surprised if the asteroids got destroyed deep enough inside Jool.

Crash tolerance, among all other data can be found in the configs and the relevant configs can be found in your gamedata-->nasa mission --> parts -->potatoroid.


// --- standard part parameters ---
mass = 150
dragModelType = default
maximum_drag = 0.2
minimum_drag = 0.2
angularDrag = 1
crashTolerance = 80
breakingForce = 200
breakingTorque = 200
maxTemp = 1e38
explosionPotential = 0.1

vesselType = SpaceObject

1e38 is a really, enormously, huge number. For some perspective, a nice day outside is about 293k.  Water boils at 373k, the temperature at earths core is about 6200k.

Sun's core? a toasty 15 million kelvin, but this is only 0.0000000000000000000000000000001% of the heat tolerance of the asteroid.

OK, so what about Planck's temperature, where it is so hot, quantum physics breaks down because the wavelength of light given off by the particles is the Planck length?

Planck's temperature is 1.417 x 1032k. Getting close right?

 

Wrong

Even at Planck's temp, you are still only 0.000142% of the way there.

Good luck @doggonemess, you are going to need it.

Seems like a tear in the fabric of Space-Time has caused an expanding bubble of altered quantum dynamics centered on the Kerbol system where the underlying fundamental physical constants have once again been altered. This seems to be a periodical occurrence, sometimes causing and resolving major alterations, at other times minor subtle shifts in the very nature of reality itself. The Kerbal's don't seem to make a big deal of it, perhaps not noticing the difference as they change along with the rest of the universe. Wehrner von Kerman did speculate once that he was living in a complex holographic simulation of reality but was then promptly distracted by Jeb crashing yet another rocket.:wink:

This is old info. Asteroids have a fairly low heat tolerance now, and tend to overheat and blow rather easily on reentry to Kerbin.

 

Y'all just had to go and make KSP obey physics, no fun to be had! It wasn't a bug! it was a feature!

To a large degree I agree with you. Most of the fun of KSP is that it's silly. Silly and sensible are basically opposites. The more logical the game gets, the less fun it is. But I'm fighting the good fight! Trying to keep the silliness in the game! It's all the other guys who think things that don't make logical sense are bugs. :wink:
