We have developed a Web‐based program for quickly estimating the regional
environmental consequences of a comet or asteroid impact on Earth (http: www. lpl. arizona …

Asteroid impacts can cause a wide range of damage through multiple potential hazards,
from localized blast waves or thermal radiation, to tsunami inundation, to global climatic …

小行星撞击地球是人类生存和发展的潜在威胁之一. 行星防御是国际上近20
年来兴起的热点研究领域, 也是我国重大安全需求. 小行星撞击地球危害评估是行星防御重要 …

A set of 50,000 artificial Earth impacting asteroids was used to obtain, for the first time,
information about the dominance of individual impact effects such as wind blast …

High entry speed (> 25 km s− 1) and low density (< 2500 kg m− 3) are the two factors that
lower the chance of a meteoroid to drop meteorites. The 26 g carbonaceous (CM 2) …

Asteroids populations are highly diverse, ranging from coherent monoliths to loosely bound
rubble piles, with a broad range of material and compositional properties. These different …

A wide range of meteors were simulated impacting Earth's atmosphere using the ALE3D
hydrocode. The size, density, strength curve, entry angle, and velocity of the meteors were …

Meteoroids represent the material remaining from the formation of the solar system and carry
unique information on the earliest forming solids. They enable the study of the structure and …

As evidenced by the Chelyabinsk and Tunguska airburst events in Russia, decameter-scale
Near-Earth Objects (NEOs) can pose a hazard to human life and infrastructure from the …

The Tunguska meteor airburst has been extensively studied and modeled in attempts to
deduce its size, properties, and impact characteristics. However, most of the existing …
