It is customarily assumed that Earth-striking meteoroids are completely random, and that all the impacts must be interpreted as uncorrelated events distributed according to Poisson statistics. If this is correct, their impact dates must be uniformly spread throughout the year and their impact coordinates must be evenly scattered on the surface of our planet. Here, we use a time- and yield-limited sample of Earth-impacting superbolides detected since 2000 to explore statistically this critical…

Far from random: dynamical groupings among the NEO population
Among the near-Earth object (NEO) population there are comets and active asteroids which are sources of fragments that initially move together; in addition, some NEOs follow orbits temporarily
Dynamical evolution of near-Earth asteroid 1991 VG
The discovery of 1991 VG on 1991 November 6 attracted an unprecedented amount of attention as it was the first near-Earth object (NEO) ever found on an Earth-like orbit. At that time, it was

Decoherence time scales for “meteoroid streams”
Abstract— We explore the orbital dynamics of Earth‐crossing objects with the intent to understand the time scales under which an “orbital stream” of material could produce time‐correlated meteorite

The Chelyabinsk superbolide was the largest known natural object to enter the Earth's atmosphere since the Tunguska event in 1908 and it has become a template to understand, manage and mitigate
The flux of small near-Earth objects colliding with the Earth
TLDR
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.
Meteor shower features: are they governed by the initial formation process or by subsequent gravitational perturbations?
The fine-structure properties found in a meteoroid stream determine what is observed in the associated meteor shower. These properties depend both on the ejection process of meteoroids from their
The Chelyabinsk superbolide: a fragment of asteroid 2011 EO40?
Bright fireballs or bolides are caused by meteoroids entering the Earth's atmosphere at high speed. On 2013 February 15, a superbolide was observed in the skies near Chelyabinsk, Russia. Such a

A 500-kiloton airburst over Chelyabinsk and an enhanced hazard from small impactors
TLDR
A global survey of airbursts of a kiloton or more is performed, and it is found that the number of impactors with diameters of tens of metres may be an order of magnitude higher than estimates based on other techniques, which suggests a non-equilibrium in the near-Earth asteroid population.
