I wonder what the effect of a plantary defence weapon of a 100m tungsten arrow shot out a super massive rail gun sending out of the atmosphere at Mach 50

I was mostly curious if it would detonate like a bomb or if it'd just pass thought like Armour Piercing, it's funny to think of literally a dart just leaving a 1m diameter hole behind a massive asteroid and it doing nothing else. Thanks for the interesting comment :)

What we need is a hollow-point tungsten arrow to shoot at asteroids.

Well I said tungsten because it's the 'strongest' metal we have but if going for hollowpoints probably the best idea would be APFSDS segmented with Aluminium spacers so it can shatter inside the asteroid dispersing more energy.

They should have done this with Don't Look Up. "Don't worry, we have a backup plan...Oh...That didn't work either."

It wouldve been great but instead everyone just gives up. A bit dull

All it has to do is slightly change the trajectory of the object. Even changing it by 1% would be enough for it to completely miss earth as 1% of a trajectory change that far from earth is good enough.
