The Rate of Falls of Meteorites and Bolides

Solar System Research, 2020
We perform a statistical analysis of 926 confirmed falls of meteorites that occurred in the period 1860 to 2017. The distribution of meteorites over masses is approximated with a lognormal law. It has been shown that the mean interval between the detections of falls of Chelyabinsk-like meteorites is ~25 years.

Meteoroid, Bolide and Meteorite «Chelyabinsk»

Materials Science Forum, 2016
This paper presents the brief review of Chelyabinsk group of meteoroid, bolide and meteorite "Chelyabinsk" investigations. Height of the maximum of the main flash of Chelyabinsk bolide is 30 km. Only 1% of meteoroid mass arrived to the Earth surface in the form of meteorites while the most part of meteoroid became dust.

On Limb Observations of Bolides

Solar System Research, 2019
The LP/OMPS limb sensor of the Suomi satellite detected the atmospheric trace of the Chelyabinsk superbolide with an energy of over 400 kt TNT in 2013. The study of LP/OMPS data shows that it detects several bolides with much less energy each year. The paper considers the cases of observation of three bolides in 2016–2017: on February 6, 2016 (13 kt ...

Il bolide d’autunno

2020
Avvistata due sere fa da sette fotocamere della rete Prisma mentre solcava i cieli della Toscana, la meteora si è spenta a circa 80 km di quota. L’alta velocità di ingresso in atmosfera e la significativa eccentricità dell'orbita inducono a ritenere che abbia un’origine ...

Bolides in the Earth Atmosphere

2007
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 asteroid-sized bodies—about 3 km in size and mass of about 10 14 kg.

IMPACT! - BOLIDES, CRATERS, AND CATASTROPHES

Elements, 2012
It is now universally accepted that the impact of planetesimals, asteroids, and comets has been a fundamental process throughout the Solar System. Catastrophic impact events have been instrumental in developing the early history of the planets and have caused environmental disasters throughout Earth history.

Radiation effect of the Chelyabinsk bolide

JETP Letters, 2016
A physical model of the action of radiation from a bolide on Earth’s lower ionosphere has been presented. The calculations within this model applied to the Chelyabinsk bolide on February 15, 2013, have reproduced the luminosity curves in the visible and infrared ranges in agreement with ground and satellite observations.

The cultural aftershock of the Chelyabinsk bolide

2019
Humankind is beset with everyday vanities, work, and family care. If any resident of Chelyabinsk had been approached and asked in January 2013 what they thought about bolides, their origin and flight velocity, they would most likely have responded with blank looks and little understanding. After the huge bolide exploded above Chelyabinsk on February 15,
