Large-Scale Asteroid Impacts Since 2001 More Than Previously Thought

13 posts in this topic

This is a very interesting article and downright scary ... the claim is that since 2001, 26 atomic-bomb-scale explosions have occurred in remote locations around the world, far from populated areas, made evident by a nuclear weapons test warning network.

This network has detected 26 multi-kiloton explosions since 2001, all of which are due to asteroid impacts. It shows that asteroid impacts are NOT rare—but actually 3-10 times more common than we previously thought. The fact that none of these asteroid impacts shown in the video was detected in advance is proof that the only thing preventing a catastrophe from a 'city-killer' sized asteroid is blind luck.

Astronauts to reveal sobering data on asteroid impacts

Apr 17, 2014 by Jason Major, Universe Today

http://phys.org/news/2014-04-astronauts-reveal-sobering-asteroid-impacts.html

This Earth Day, Tuesday, April 22, three former NASA astronauts will present new evidence that our planet has experienced many more large-scale asteroid impacts over the past decade than previously thought… three to ten times more, in fact. A new visualization of data from a nuclear weapons warning network, to be unveiled by B612 Foundation CEO Ed Lu during the evening event at Seattle's Museum of Flight, shows that "the only thing preventing a catastrophe from a 'city-killer' sized asteroid is blind luck."

Well not really, I believe that earlier mankind, had many falling objects from space, and that is why most of the "falling rocks" are basically landing in non-residential areas. Speaking of being funny and all, New Jersey was once again hit by another Godzilla occurrence. The way I see it, is that we are blessed. My question is, the asteroid belt, that surrounds the inner solar system, is it, a belt or is it a sphere???

I say we are blessed because, the only thing worst then a room of saints is a room of sinners. Thank the world for the saints.

I would say "belt" The planets are all on a plane and orbiting in the same direction (Unless someone knows different)

It's a belt. All of the planets, and asteroid belt too, are on the plane of the ecliptic. Which is a line extending from the sun outwards to all the planets. So, you can imagine the solar system being relatively flat and disc shaped.

For example, if you draw an imaginary line extending straight from the Sun to the Earth, this is called the plane of the ecliptic. The Earth would then have an orbital inclination of zero degrees from the ecliptic.

Going by this same line (Sun to Earth), Mercury would have a orbital inclination of 7 degrees from the ecliptic , Venus 3.2 degrees, Mars 1.9 degrees, Jupiter 1.3 degrees, Saturn 2.5 degrees*. As you can see, the orbital inclinations are slight. From an outside viewpoint it would look flat.

Which asteroid belt are we talking about. The Main belt or the near-earth belt. Both are threating.

Well, there's only one asteroid "belt" between Mars and Jupiter.

However, there is also the Kuiper "belt" beyond the orbit of Neptune/Pluto. These are comet-like bodies of frozen ice. They're not the same as the "rocks" in the regular asteroid belt between Mars and Jupiter.

But there are asteroids that have highly eccentric orbits that aren't part of the asteroid belt. Instead they approach the inner solar sytem near Earth, then go back out. These can be labeled "Earth Grazers."

Eros was the first "earth grazer" discovered. Later on, more earth grazing asteroids were discovered. The next one was called Apollo, and its orbit was found to pass within Earth's orbit even closer than Eros. So they started calling these asteroids "apollo objects."

A few Apollo-objects:

Icarus

Hermes

Apollo

Cerberus

Daedulus

Adonis

Midas

Of course, that was back in the 70's, and solar system nomenclature has evolved since then. I don't know if they still use that terminology. Ah, they do! Here's the wikipedia article on Apollo Asteroids.

Thank you for the clarification. I'm no expert on solar bodies/objects. I do know however that jupiter is a huge savior for us since its intense gravity (besides warming up the moon europea giving chace for live with its gravity tug of war) that sucks up alot of asteroids. Curious though would you happen to know Lostinspace the current "threats" of earth near objects.

*typos*

Sure, you can visit here, and click on the Impact Risk tab :-)

This is maybe sort of technical.

But 1 "AU" is one "Astronomical Unit". Which is the distance of the Sun to the Earth; something like 93 million miles. It's easier to measure in AU than miles.

Generally I wouldn't worry about it though.

Thanks again Lostinspace. I knew that there were many objects in danger proximity of earth (pha), but I did not know that there were nearly 1500 close to us. I find this section really interesting http://neo.jpl.nasa.gov/ca

Great, great informational posts about a real concern. It's just a matter of time.

Very interesting. Thanks to all the posters.

I've planned ahead for the big asteroid impact on my house:

I have 2 large cardboard boxes -- one inside the other -- and in-between the boxes, I've filled it with bubble wrap -- and I'll crawl in the inner box when the impact is imminent. I'm pretty sure that will protect me.

JUST KIDDING, OF COURSE !!!

I have 3 large cardboard boxes -- with the unit made as described above.

LOL :-)

Bubble wrap, eh?

You're going to need more like an underground fallout shelter....

Ever see the movie "Blast From the Past" with Christopher Walken, Brandon Frasier, and Alicia Silverstone? They had like a greenhouse down there, decades worth of canned goods, their own generator, food, clothes, etc.

If you haven't seen that movie, it's hilarious.

Any sufficiently strong enough asteroid will create a nuclear-winter type affect and basically render the Earth inhabitable for quite some time.

Hey, Flasche, here's another link, less math involved which is a good thing ;-)

Dont forget to put an umbrella on your house. ;)

What are talking about he is perfectly safe. :P (still needs that umbrella though)

@LostInSpace2014:

No, I didn't see "Blast from the Past", but I did see "Deep Impact", a fantastic movie, IMO.

@Flasche:

Thanks for the suggestion.

I'll be sure to put a dumbrella over my house.

Nylon, not polyester, 'cause nylon be much stronger
