Re: Near miss asteroid

That figures, Judd. Wikipedia. Plot

In 2154, Earth citizens live in poverty, and with inadequate medical care. The rich and powerful live on Elysium—a gigantic space habitat in Earth's orbit. Elysium is technologically advanced, with devices such as Med-Bays that can cure all diseases, reverse the aging process, and regenerate body parts...

Re: Near miss asteroid

Asteroids have been striking earth since the formation of our planet. The one which recently passed us, "only" a mile wide, would, of course, do catastrophic damage, but it would not wipe out all life on earth. At that size even humans would mange to eke out an existence.

The monster asteroid which wiped out the dinosaurs, 65 million years ago, was between 6 -9 miles wide, and struck the Yucatan, in Mexico.

In any event, the skies would eventually clear and life would continue to evolve.

Re: Near miss asteroid

https://science.howstuffworks.com/na...hits-earth.htm

So, what if an asteroid were to hit Earth today?

Any asteroid falling from the sky would have a tremendous amount of energy. Here's a typical example. In 2028, the asteroid 1997XF11 will come extremely close to Earth but will miss the planet. If something were to change and it did hit Earth, what you would have is a mile-wide asteroid striking the planet's surface at about 30,000 mph It's very likely that an asteroid like this would wipe out most of the life on the planet.

By the time you get up to a mile-wide asteroid, you are working in the 1 million megaton range. This asteroid has the energy that's 10 million times greater than the bomb that fell on Hiroshima. It's able to flatten everything for 100 to 200 miles out from ground zero. In other words, if a mile-wide asteroid were to directly hit New York City, the force of the impact probably would completely flatten every single thing from Washington D.C. to Boston, and would cause extensive damage perhaps 1,000 miles out -- that's as far away as Chicago. The amount of dust and debris thrown up into the atmosphere would block out the sun and cause most living things on the planet to perish. If an asteroid that big were to land in the ocean, it would cause massive tidal waves hundreds of feet high that would completely scrub the coastlines in the vicinity.

In other words, if an asteroid strikes Earth, it will be a really, really bad day no matter how big it is. If the asteroid is a mile in diameter, it's likely to wipe out life on the planet.

Another one to check out is the book Lucifer's Hammer. Although not a meteor, it still is a classic of apocalyptic spacial collision.
