In this paper a statistical comparison of the AAA asteroids with the other
asteroid populations is presented and discussed. For the analysis the database
of the osculating orbital elements (Epoch = 2451200.5) of the 47098 asteroids
(February 1999) provided at the Lowell Observatory, Flagstaff, Arizona, U.S.A
was used. Two kinds of distributions are presented: (1) The frequency
distributions of the orbital elements e, i, omega, Omega and absolute magnitude
H; (2) The distributions like a vs. e, H vs. i and H vs. r_(min), where r_(min)
is the minimum distance between the orbits of the Earth and an asteroid. The
analysis was aimed to study some special features of the AAA asteroid
population like its spatial distribution and size of the asteroids in it and
to compare them with the other groups of asteroids.
