Debiased orbit and absolute-magnitude distributions for near-Earth objects

26 Apr 2018 Granvik Mikael Morbidelli Alessandro Jedicke Robert Bolin Bryce Bottke William Beshore Edward Vokrouhlicky David Nesvorny David Michel Patrick

The debiased absolute-magnitude and orbit distributions as well as source regions for near-Earth objects (NEOs) provide a fundamental frame of reference for studies of individual NEOs and more complex population-level questions. We present a new four-dimensional model of the NEO population that describes debiased steady-state distributions of semimajor axis, eccentricity, inclination, and absolute magnitude $H$ in the range $17<H<25$...
