Question:
Could an un-noticed asteroid of any size really strike Earthat any time? At what distance and of what mass would a body be unfailingly spotted every time?

Replies:
Yes, relatively few people are watching asteroids with the intention of warning us when one threatens. After a body larger than a basketball has entered the atmosphere, everyone would notice.
