I estimate the size and shape of the near-Earth asteroid (NEA) population using survey data from the Lincoln Near-Earth Asteroid Research (LINEAR) project, covering 375,000 square degrees of sky and including more than 1300 NEA detections. A simulation of detection probabilities for different values of orbital parameters and sizes combined with the detection statistics in a Bayesian framework provides a correction for observational bias and yields the NEA population distribution as a function… 

Observational constraints on the number, albedos, size, and impact hazards of the near-Earth asteroids

This work provides a statistical description of the near-Earth asteroids (NEAs) in terms of number, orbital parameters, reflectance spectra, albedos, diameters, and terrestrial and lunar collision

From Magnitudes to Diameters: The Albedo Distribution of Near Earth Objects and the Earth Collision Hazard

Abstract A recently published model of the Near Earth Object (NEO) orbital–magnitude distribution (Bottke et al. , 2002, Icarus 156 , 399–433.) relies on five intermediate sources for the NEO

Dynamical Origin and Terrestrial Impact Flux of Large Near-Earth Asteroids

Dynamical models of the asteroid delivery from the main belt suggest that the current impact flux of diameter km asteroids on the Earth is ≃0.5–1 Gyr−1. Studies of the Near-Earth Asteroid (NEA)

Near-earth object survey simulations with a revised population model

We carried out a set of simulations to reproduce the performance of wide-field NEO surveys based on the revised population model of Near Earth Objects (NEOs) constructed by Morbidelli (2006). This is

Nonextensive distributions of asteroid rotation periods and diameters

Context. We investigate the distribution of asteroid rotation periods from different regions of the solar system and diameter distributions of near-Earth asteroids (NEAs). Aims. We aim to verify if

The Yarkovsky-driven origin of near-Earth asteroids

We investigate the relevance of the Yarkovsky effect for the origin of kilometer and multikilometer near-Earth asteroids (NEAs). The Yarkovsky effect causes a slow migration in semimajor axis of main

Understanding the distribution of near-earth asteroids

We have deduced the orbital and size distributions of the near-Earth asteroids (NEAs) by (i) numerically integrating NEAs from their source regions to their observed orbits, (ii) estimating the

A reduced estimate of the number of kilometre-sized near-Earth asteroids

TLDR
An analysis of the survey for near-Earth asteroids that uses improved detection technologies finds that the total number of asteroids with diameters > 1 km is about half the earlier estimates.
