“a relatively small metallic asteroid with a diameter of 0.99 miles”
I’m horizontal tapping on an iPad or I’d do some calculations on the amount of energy it would take to drop that down to the Earth at a reasonable descent rate. You drop that thing at full speed and i bet it would make the Hiroshima bomb look like a picnic.
Maybe crash it onto the moon, mine it and slingshot the finished material to Earth?
