## [16.03] The Near-Earth Asteroid Population from Lincoln Near-Earth Asteroid Research Project Data

*J.S. Stuart (MIT Lincoln Laboratory, MIT Dept Earth, Atmos., & Planetary Sciences)*

We analyze 2.5 years of astronomical data from the Lincoln
Near-Earth Asteroid Research (LINEAR) project to derive an
estimate of the near-Earth asteroid (NEA) population. A
Bayesian framework is used to correct for observational bias
in the observed population, and the population distribution
is estimated as a function of the absolute magnitude. A
population distribution over the orbital parameters is
assumed based upon the currently known population, while the
prior population distribution over the absolute magnitude
parameter is modeled as an exponential function of absolute
magnitude. The large number of NEA detections from the
LINEAR data, and the Bayesian analysis methodology provide a
more robust estimate of the population than previously
published estimates.
