“Changing the asteroid's velocity changes the time when the asteroid crosses Earth's orbit. After all, just because it crosses Earth's path doesn't mean there is necessarily going to be a collision. It has to cross Earth's path when the Earth is right there.”
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
An asteroid's collision risk depends on timing; crossing Earth's orbit alone isn’t enough, the Earth must be present at that point.
In simple terms: Collision risk needs both path and timing.
Key Takeaway
Consider both trajectory and timing for impact assessments.
