1870 feet in diameter...much bigger than the 66 foot diameter Chelyabinsk meteor over Russia back in 2013. No kidding!

Ratio of volumes (assuming spheres) and masses (and impact energy) is (1,870/66)^3 ~ 23,000.

How big do you need for extinction?

the Chixilub impact landed in a gypsum deposit and liberated a huge quantity of sulfur compounds. but it was 6+ miles across.

if this one lands in a similar type spot we will have problems and if it lands in water the coasts are toast.

If one this size hits land it will end civilization as we know it. If it hits ocean the tsunami would change the coastlines all around the ocean it hit and send enough water vapor into the atmosphere to raise global temps by a few degrees (a catastrophe). If it hits in either polar region the oceans rise would alter civilization significantly but not be an extinction event.

Chicxulub was about 10 km.

But that was a worst case, a shallow water strike over carbonaceous rock.
