wake-up call was in 1994.
That's when we witnessed a series of impacts that released thousands of times as much destructive energy as the entire global nuclear arsenal of all
21 distinct impacts were observed, with the largest coming on July 18 at 07:33 UTC when fragment G struck Jupiter. This impact created a giant
dark spot over 12,000 km across, and was estimated to have released an energy equivalent to 6,000,000 megatons of TNT (600 times the world's nuclear
And that was only one fragment, there were 20 others.
That was the year it seemed like the threat was finally appreciated, and the search for objects that could impact Earth got more emphasis, and it
continues to this day but we haven't found everything yet.
As recently as 1908 there was an impact in Tunguska that would have killed millions had it struck a populated area instead of an unpopulated area.
While those events are rare, they do happen every few centuries, and we will probably have more like it unless NASA finds the objects in time and is
able to divert them from impacting the Earth.
The smaller objects the size of a truck or less happen more frequently and cause huge fireballs like this, but they don't do any damage.
