6 to 7 grams? No. 1/4 of a gram of antimatter reacting with 1/4 gram of matter is just about the right mix. That’ll be around 15 kilotons.

I re-did the calculation. You are closer, but the conversion of half a gram yields about 10 kilotonnes. Makes the meteorite a bit worse.

Calculation based on 4'184'000'000'000 joules per kiloton TNT.

Now we just gotta ramp up production at LHC. Nobody tell them what the antimatter is for.
