What energy release is generally associated with an impact by a 1-kilometer diameter bolide?
Answer
10,000+ megatons of TNT
Bolides with a diameter of approximately 1 kilometer are capable of releasing over 10,000 megatons of energy upon impact. This level of energy is sufficient to cause global climate disruption. Such events are rare, occurring roughly once every million years, but they represent a significant threat to global stability compared to smaller airbursts.
