"WebA measure of how infrequent the Earth close approach is for asteroids of the same size and larger: 0 means an average frequency of 100 per year, i.e., roughly every few days or less, 1 corresponds to roughly once a month, 2 to roughly once a year, 3 to roughly once a decade, etc. 'n/a' means that a frequency estimate is not available.
