The following is a list of Near Earth asteroids from the Numbered
Asteroids 1 - 4767. A NEA is defined as an asteroid whose perihelion
distance (q) is <= 1.20. Since the Earth's orbit is 1 AU out, any
asteroid with a q of <=1.0 will be an Earth crosser. In addition to
those in this list, there are numerous others that have not been
observed over a period of time long enough to calculate a definitive
orbit. NEAs in this category are not given numbers, but designations
only, such as 1991 BA. The designation is the year of discovery, the
half-month, and the order of discovery in that half-month. 1991 BA
therefore would be the for an asteroid discovered in the second
half-month of 1991 (i.e., A=first half-month and B=second half of
January), and the first discovery of that half-month. The very next
asteroid discovery (whether NEA or not) reported to the Minor Planet
Center would receive the designation 1991 BB, then BC ... and so on.
When February rolls around the designations would go 1991 CA .. CB ..
CD .. DA .. DB ...
