an object of unspecified size travelling at 24.4 kilometres per second struck earth in Greenland...releasing 2.1 kilotons of force energy.

Well if you state the velocity and energy then the size, e.g. the mass is already specified and, assuming my arithmetic is correct works out to be about 28,000kgs or 28 metric tons. If this were a sphere of solid iron it would be a diameter of just shy of 2 m.

And per the article, 24.4 km/s = 24,500 mi/hr. That’s some serious KE going on. Thanks for the math. That’s the first thing I do when figures are quoted in a write up. Many times quoted numbers are bogus.

Can you state that in American, or is that considered un-pc these days?
