The flux of small near-Earth objects colliding with the Earth

@article{Brown2002TheFO,  title={The flux of small near-Earth objects colliding with the Earth},  author={Peter Brown and Peter G. Brown and Richard E. Spalding and Douglas Orson Revelle and Edward Tagliaferri and Simon P. Worden},  journal={Nature},  year={2002},  volume={420},  pages={294-296},  url={https://api.semanticscholar.org/CorpusID:4380864}}
Satellite records of bolide detonations in the atmosphere over the past 8.5 years are reported and it is found that the flux of objects in the 1–10-m size range has the same power-law distribution as bodies with diameters >50 m.

The rate of small impacts on Earth

Abstract— Asteroids tens to hundreds of meters in diameter constitute the most immediate impact hazard to human populations, yet the rate at which they arrive at Earth's surface is poorly known.

Number of Near-Earth Objects and Formation of Lunar Craters over the Last Billion Years

We compare the number of lunar craters larger than 15 km across and younger than 1.1 Ga to the estimates of the number of craters that could have been formed for 1.1 Ga if the number of near-Earth

An estimate of the terrestrial influx of large meteoroids from infrasonic measurements

[1] The influx rate of meteoroids hitting the Earth is most uncertain at sizes of � 10 m. Here we make use of historical data of large bolides recorded infrasonically over a period of 13 years by the

NEOMOD: A New Orbital Distribution Model for Near-Earth Objects

Near-Earth Objects (NEOs) are a transient population of small bodies with orbits near or in the terrestrial planet region. They represent a mid-stage in the dynamical cycle of asteroids and comets,

Small Near-Earth Asteroids as a Source of Meteorites

Small asteroids intersecting Earth's orbit can deliver extraterrestrial rocks to the Earth, called meteorites. This process is accompanied by a luminous phenomena in the atmosphere, called bolides or

Efficient disruption of small asteroids by Earth's atmosphere

It is shown that the separated-fragments model predicts the total atmospheric disruption of much larger stony bodies than previously thought, and it is estimated that bodies >220 m in diameter will impact every 170,000 years.

Understanding the Near-Earth Object Population: the 2004 Perspective

Over the last several decades, evidence has steadily mounted that asteroids and comets have impacted the Earth over solar system history. This population is commonly referred to as “near-Earth

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

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.

ASTEROID AND COMET BOMBARDMENT OF THE EARTH

Two classes of solid bodies large enough to be detected by telescopes occur in orbits that overlap that of the Earth. These bodies are the Earth-crossing asteroids and comet nuclei. Although their

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

The Near-Earth Asteroid Size–Frequency Distribution: A Snapshot of the Lunar Impactor Size–Frequency Distribution

Abstract It is shown that the size–frequency distribution (SFD) of a time-averaged projectile population derived from the lunar crater SFD of Neukum and Ivanov (in Hazards Due to Comets and Asteroids

Historical Detection of Atmospheric Impacts by Large Bolides Using Acoustic‐Gravity Waves a

ABSTRACT: During the period from about 1960 to the early 1980's a number of large bolides (meteor‐fireballs) entered the atmosphere which were sufficiently large to generate blast waves during their

Detection of a meteoroid entry into the Earth's atmosphere on February 1, 1994

Infrared and visible wavelength sensors on board platforms operated by the U.S. Department of Defense detected an energy release over the central Pacific Ocean on February 1, 1994, estimated to be of

Luminous efficiencies of bolides

Observational data on luminosity of bolides observed from ground-based stations as well as from satellite systems can be converted into masses or sizes of bodies assuming we know the luminous

Hazards Due to Comets and Asteroids

In 1993, the U.S. Department of Defense declassified information dealing with frequent explosions in the upper atmosphere caused by meteoric impact. It is estimated that impacts have occurred of a

The NEA population is more highly inclined than previously estimated, and the total number of kilometer-sized NEAs is 1227−90 +170 (1σ).
