On 2013 February 15 a small asteroid rammed against the atmosphere above the region of Chelyabinsk in Russia, producing the most powerful superbolide since the Tunguska event in 1908. Lacking proper astrometric observations, the pre-impact orbit of this object has been determined using videos, satellite images, and pure geometry. Unfortunately, more than two years after the event, the published estimates vary so much that there is no clear orbital solution that could be used to investigate the… 
Asteroid (469219) 2016 HO3, the smallest and closest Earth quasi-satellite
A number of Earth co-orbital asteroids experience repeated transitions between the quasi-satellite and horseshoe dynamical states. Asteroids 2001 GO2, 2002 AA29, 2003 YN107 and 2015 SO2 are
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
Homing in for New Year: impact parameters and pre-impact orbital evolution of meteoroid 2014 AA
On 2008 October 7, small asteroid 2008TC3$2008~\mbox{TC}_{3}$ turned itself into the parent body of the first meteor ever to be predicted before entering the Earth’s atmosphere. Over five years
On the Pre-impact Orbital Evolution of 2018 LA, Parent Body of the Bright Fireball Observed Over Botswana on 2018 June 2
On 2018 June 2, meteoroid 2018 LA became the third natural body ever to be observed before entering our atmosphere ---small asteroids 2014 AA and 2008 TC3 had stricken the Earth on 2014 January 2 and
The Chelyabinsk meteorite: Thermal history and variable shock effects recorded by the 40Ar‐39Ar system
We studied three lithologies (light and dark chondritic and impact melt rock) differing in shock stage from the LL5 chondrite Chelyabinsk. Using the 40Ar‐39Ar dating technique, we identified low‐ and
Streams and the Milky Way dark matter halo
Abstract We describe an algorithm that can fit the properties of the dwarf galaxy progenitor of a tidal stream, given the properties of that stream. We show that under ideal conditions (the Milky Way

Reconstructing the Chelyabinsk event: pre-impact orbital evolution
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 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
The orbit of the Chelyabinsk event impactor as reconstructed from amateur and public footage
A ballistic reconstruction of a meteoroid orbit can be made if enough information is available about its trajectory inside the atmosphere. A few methods have been devised in the past and used in
The orbit and dynamical evolution of the Chelyabinsk object
The orbit of the Chelyabinsk object is calculated, applying the least‐squares method directly to astrometric positions. The dynamical evolution of this object in the past is studied by integrating
The trajectory, structure and origin of the Chelyabinsk asteroidal impactor
TLDR
An analysis of selected video records of the Chelyabinsk superbolide of 15 February 2013 found that its orbit was similar to the orbit of the two-kilometre-diameter asteroid 86039, to a degree of statistical significance sufficient to suggest that the two were once part of the same object.

Minor bodies trapped in 1:1 co-orbital resonances with a host planet could be relevant to explain the origin of captured satellites. Among the giant planets, Uranus has one of the smallest known
Earth-viewing satellite perspectives on the Chelyabinsk meteor event
TLDR
Satellite observations of the Chelyabinsk superbolide debris trail, collected within minutes of its entry, demonstrate the general ability of Earth-viewing satellites to provide valuable insight on trajectory reconstruction in the more likely scenario of sparse or nonexistent surface observations.

Chelyabinsk Airburst, Damage Assessment, Meteorite Recovery, and Characterization
TLDR
The asteroid impact near the Russian city of Chelyabinsk on 15 February 2013 was the largest airburst on Earth since the 1908 Tunguska event, causing a natural disaster in an area with a population exceeding one million.
