[edit] Summary

A comparison of the distribution of asteroid semi-major axis. Lines correspond to different absolute magnitudes H (which correlates to size).

  • Blue: H>13, roughly diameters greater than 6-15 km
  • Green:H>15, roughly diameters greater than 2.5-6 km
  • Black:H>17, almost all known asteroids, diameters greater than 1-2.5 km.

The green to black difference is clearly due to observational bias (asteroids in the inner main belt are better illuminated, closer, and have higher albedos).

Orbital elements taken from the astorb database. This data was dated 27 Dec 2005, and computed by Edward Bowell.

The "relative density" has been normalised so that the area under the line is one.
