Asteroids with diameters smaller than ∼50–100 m that collide with the Earth usually do not hit the ground as a single body; rather, they detonate in the atmosphere. These small objects can still cause considerable damage, such as occurred near Tunguska, Siberia, in 1908. The flux of small bodies is poorly constrained, however, in part because ground-based observational searches pursue strategies that lead them preferentially to find larger objects. A Tunguska-class event—the energy of which we… 
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
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
Bolides in the Earth Atmosphere
The incremental influx of cosmic material on the Earth shows few maxima in the depen- dence on the size of falling meteoroids (Ceplecha 1992). The largest one corresponds to the impact of


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.
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
A Near-Earth Asteroid Population Estimate from the LINEAR Survey
The NEA population is more highly inclined than previously estimated, and the total number of kilometer-sized NEAs is 1227−90 +170 (1σ).
