Basic definitions about asteroids.
Astronomical Distance: one astronomical unit (AU) is equal to 92,955,807 miles or 149,597,871 kilometers.
Lunar distance: is equal to 384402 km, that is the Moon's average distance to Earth.
Perihelion Distance is the distance between the orbiting body and the sun at its closest approach.
Eccentricity (e) is the ratio of half the distance between the foci c to the semi-major axis a: e=c/a. e=0 is circular, e=1 is parabolic, and e between 0 and 1 is elliptic.
Very special thanks to NASA for sharing precious data about the space with us.
