It is indeed historical. The ancient Greeks divided the stars in 6 categories or magnitudes, magnitude 1 for the brightest stars to 6 for those barely visible with the naked eye. The mathematical formula only emerged later (1856 by Pogson) who defined the brightness scale by: a magnitude 1 star is 100 times brighter than a magnitude 6 star and Polaris is magnitude 2 which more or less fitted the ancient magnitude scale.

There are only 2 types of Earth crossing asteroids: Apollos with a semi major axis larger than 1AU and perihelion smaller than Earth's aphelion and Atens with a semi major axis smaller than 1AU and aphelion larger than Earth's perihelion. There are 4803 known Apollo asteroids (I don't know where the 5200 number in the summary comes from but IAU's Minor Planet Center knows of only 4803) and 747 known Atens, so there was a very good chance that the meteorite was an Apollo...
