In The Moon is a Harsh Mistress (1966) by Robert A. Heinlein, the lunar colonists repurpose a mass driver to launch large rocks at Earth as kinetic bombardment weapons. These projectiles rely solely on impact energy and are used as a form of asymmetric warfare against Earth's superior forces.
The Chesapeake Bay impact crater is a buried impact crater, located beneath the mouth of Chesapeake Bay, United States.It was formed by a bolide that struck the eastern shore of North America about 35.5 ± 0.3 million years ago, in the late Eocene epoch.
The table below is arranged by the continent's percentage of the Earth's land area, and where Asian and Russian structures are grouped together per EID convention. The global distribution of known impact structures apparently shows a surprising asymmetry, [ 37 ] with the small but well-funded European continent having a large percentage of ...
An impact crater is a depression in the surface of a solid astronomical body formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, [2] impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain.

Asteroid 2024 YR4 has a 1.3% chance of impacting Earth in 2032, NASA reports. Astronomers all over the world are watching the asteroid, trying to narrow down its future path.
The aftermath of the asteroid collision, which occurred approximately 66 million years ago, is believed to have caused the mass extinction of non-avian dinosaurs and many other species on Earth. [13] The impact spewed hundreds of billions of tons of sulfur into the atmosphere, producing a worldwide blackout and freezing temperatures which ...
That’s the day an asteroid dubbed 2024 YR4 may strike our planet. Cosmic bookmakers don’t make an impact terribly likely. Cosmic bookmakers don’t make an impact terribly likely. According to ...
The European Space Agency in January placed the asteroid's odds of hitting Earth at roughly 1%, before NASA's Jet Propulsion Laboratory estimated the risk was more like 1.6% at the tail end of the ...
