>>12067095Let's do the math:
To get an idea of the scale of this object, a 60 mile (approx 97 km) wide asteroid would at the point of impact only barely be completely inside of the athmosphere, with 100km above the surface being the defined edge of space.
Assuming a prefectly spherical object with a radius of 50 km, its volume would be .
Assuming the asteroid has the same density as the earth (~ 5.5 kg/m^3) the asteroid would have a mass of ca.
Traveling at ca v=13000 m/s relative to the surface of the earth on impact its kinetic energy which would be released would equal approximately a whopping
or about gigatons of tnt, which is on par with the dinosaur killer (which was ~150 km wide).
That would be world ending.
