So it would be equivalent to a pretty big nuke. More or less a city-killer. No effects more major than that, though.
- tpmx 4y agoThe vast majority of possible impact zones on Earth are mostly uninhabited. We'd be really unlucky to have one of these hit a city. https://www.visualcapitalist.com/wp-content/uploads/2020/08/global-population-density-spikes-3d-mapped-full.png https://www.visualcapitalist.com/wp-content/uploads/2020/08/...
- jakzurr 4y agoYeah, pretty big - en.wikipedia says maybe 100 MT. https://en.m.wikipedia.org/wiki/(367789)_2011_AG5 https://en.m.wikipedia.org/wiki/(367789)_2011_AG5
- daveslash 4y agoI think it depends quite a bit on things like angle and speed. I'm sure that if it came in behind Earth, in a similar orbit, at an angle it'd be very different from a head on 90 degree angle collision with it headed in the opposite direction. Size alone is probably not a great factor to estimate damage. A starting point, but not final word.
