How frequently do asteroid-like objects the size of a football field, or roughly 100 meters, typically strike the Earth?
Answer
Every 10,000 years
The frequency of impact events is directly tied to the size of the impactor. While microscopic particles, such as dust and sand, strike the Earth daily, larger objects are exponentially rarer. An object roughly the size of a football field, or approximately 100 meters in diameter, is significant enough to cause severe regional destruction and poses a tsunami risk if it strikes the ocean. Current scientific estimates place the frequency of these particular events at once every 10,000 years, underscoring that while such impacts are not routine on a human timescale, they are an inevitable part of the Earth's long-term environmental cycle.
