ASTEROID IMPACT: A QUESTION OF SIZE AND MASS

ASTEROID IMPACT: A QUESTION OF SIZE AND MASS

Question: What would be the approximate mass and velocity of a "rock"
entering the atmosphe
a) in order for it to strike the earth at a terminal velocity of
approximately 55 m/s,
b) weighing about 45 kilograms?

I am assuming,

1, that the 'rock' (asteroid) would hit the atmosphere, become a
meteor and burn,
2, that the remnant of the meteor would slow,
3, that the remaining 'stone' (meteorite) would fall at terminal
velocity,
4, and hit the earth at about 45 kg.


Is there some kind of "average range" for mass and velocity that might
produce the specified result?

thanks....

So science is all wrong yada yada, yet you can't work out some simple
kinematics and need to ask those pesky scientists with their Babylon science


BAWAHAHAHAHAHAHHAHAHHAHAHHAHAHA

Hit the earth at 45kg

BWAHAHAHAHHAHAHHAHAHAHHAHA

Boy (assumption) playing with you is just SO much fun...

Clue one for the clueless:
There is a difference between the "technique" (or the craft,) and the
Philosophy behind the "craft."

Clue two
Technique makes great toys and gizmos, but THAT does not prove the
Philosophy called "science"

Clue three for the lost
There is no problem with the practical application of intellect and
knowledge, any "Problem" is in the illogic and sophistry behind the
methodology.

Having confessed that you cannot comprehend the separation of the
"Philosophy of science" from the "methodology in practice" you may now
go back to sleep.

Yes, the Philosophy of science is delusion and sophistry.

However, the methods and technology work fine to make nice toys.

Having cleared that lack of understanding, what would be the mass and
velocity range you would estimate?



Thanks

You truly don't understand science do you.? Perhaps you should go live in the
woods some more.

Yep - more ******** from the loon. You are just another loon who thinks that
because relativity and QM yield results you don't understand - that that means
they are wrong. Ignorant AND arrogant.

"Philosophy of science" from the "methodology in practice" you may now

Nonsense. Particularly poignant that someone so ignorant of modern science
should try and seek the higher ground by claiming sophistry. How much real
science have you done, loon?

Learn some simple maths and classical mechanics and work it out yourself. Teach
yourself to fish before begging ...

I have no intention to help you troll any more. I'm just waiting for you to get
into full flow as I can sense several kook awards in your near future.


Oh, there is more than math to this question:
For example, what is the density of the usual space "Rock"?
What is the composition? Basalt, Granite? Other?

Compostition, density, mass, temperature, velocity -- hummmmm.....
How much material will melt away while the "stone" is slowed to
terminal velicity by atmospheric drag?

However,
Since you have been so helpful,

The next part of the problem for your erudite consideration:

There is not one object (asteroid) or "stone" -- there are thousands,
hundreds of thousands, millions.

This mass of asteroids is moving toward the Sun in a long cloud, so
that the earth will pass through the cloud, and meteorites (stones)
will fall on the earth for about 24 hours.

What may be the possible configuration of such a cloud of asteroids?
It may be 25 to 50 thousands, or hundreds of thousands, of miles long,
It may be 25 to 50 thousands of miles in diameter.

What would be the density of the cloud, so that thousands or hundreds
of thousands of meteorites (stones) fall on all of the earth?

Since such a cloud is approaching the earth, when will astronomers
detect it? How long, before it begins to strike the earth, will
Astronomers be able to see it?

If such a cloud were moving directly toward the Sun, such that its
length were aligned toward and away from the sun, so that the earth
would pass through its diameter in 24 hours, how wide would that cloud
be?

Once we get some range of possible answers to these questions, we will
continue to effects.

with your nonsense.

It is not nonsense -- even if you don't like the idea...

Think about it. There is a lot of agitation about the posibility of a
large asteroid striking the earth.
(see the recent post, in this group)-(see the news) (****, do google,
I do.)

But that is just sensationalism. (What is that? how to get a grant?)
(Or maybe that's "publish or perish?) There is no discussion - that I
can find - of small bodies impacting earth.

What? you don't think it's possible? Or you just don't want to thnk
about it?

Why can't you comprehend the possiblilty of Sol System passing through
the remnant of some intergalatic gravel bed? What, there are no bodies
able to throw a large number of small bodies out of Sol's Ort Cloud?

I took a basic astonomy class. "Basic" astronomy does not cover the
questions I have.

I've done some reading; but I'm an artist and writer, math does not
compute.

So I can find out the wiight (mass) of a substance. Basalt. Fine.
What is the weight to volume?
How large is a 45 - 46 kg lump of Basalt.
What is the melting temperature of Basalt?

If an asteroid of basalt impacts the earth's atmosphere at 9 Km/s -
what size must that body be to impact the earth at terminal velocity
(say, 55 m/s) with 45kg mass remaining?

You get "atmospheric breaking" in a "basic astronomy" Class?


Well, Puddles, it has been entertaining and instructive discussing
asteroid impact dynamics with you... ;-)

enjoy.....

You're still a loon.

You're still a closed minded bufoon,
but at least you don't use dirty words, chew tobaccy and spit.


Now that we've got THAT detail out of the way....on to effects....


We were discussing the approach of a large cloud (or 'swarm') of small
asteroid bodies, and the expected effects.

There are, of course a nearly infinite number of directions. However,
an approach near the plane of the ecliptic (or galactic plane) seems
most reasonable. Four general directions seem likely: from behind, or
following, the direction of the sun's galactic orbit, or from ahead.
The approach may be from inside the central area of the galaxy, or
from outside moving inward.

If this cloud of asteroids approaches earth from the direction of the
sun, falling bodies would strike the dayside of earth. An approach
from the side away from sol would mean the falling bodies would strike
the night side of earth.

In either case, it seems likely that the approach of the asteroids
should be visible as they strike the planets between the cloud and the
sun, or between the cloud and the earth.

That is, if the cloud enters the solar system on the same side of the
sun as the earth, and crosses the orbits of the outer planets, the
impacts of those bodies should be visible to astronomers.

On the other hand, if the cloud enters the solar system on the side of
the sun away from the earth, then impacts on the outer planets should
still be visible to astronomers, and those that fall into the sun
would be visible during the day as comets.

In either case, depending on the velocity of the swarm of asteroids,
the approach should be visible for some time, giving World Governments
and People some time for preparation.

Now listen, Puddles, I'm not asking anyone (you) to LIKE this idea,
and I'm not asking anyone to AGREE to the idea, I'm asking you to
CONSIDER the idea and THINK about it.

So far your input has been scanty and of marginal value --
I hope you will take a little time to consider your response so you
may add something of value rather than negative skepticism (positive
skepticism would be an improvement).

Any contribution would be greatly appreciated ;-)

You are very confused. Asteroids are planetary system bodies, so why should
there be huge clouds of them in the galaxy not associated with stellar systems.
Also if they are orbiting in the plane of the galaxy, at the same distance as
the sun they would orbit at the same velocity = no threat.


If this cloud of asteroids approaches earth from the direction of the
sun, falling bodies would strike the dayside of earth. An approach
from the side away from sol would mean the falling bodies would strike
the night side of earth.


You should stop watching Armageddon


In either case, it seems likely that the approach of the asteroids
should be visible as they strike the planets between the cloud and the
sun, or between the cloud and the earth.

These mythical interstellar asteroids?


That is, if the cloud enters the solar system on the same side of the

On the other hand, if the cloud enters the solar system on the side of

still be visible to astronomers, and those that fall into the sun
would be visible during the day as comets.

So astronomers are "good" right now?


In either case, depending on the velocity of the swarm of asteroids,
the approach should be visible for some time, giving World Governments
and People some time for preparation.

Now listen, Puddles, I'm not asking anyone (you) to LIKE this idea,
and I'm not asking anyone to AGREE to the idea, I'm asking you to
CONSIDER the idea and THINK about it.

Its likelihood is around 10^{1001}.


So far your input has been scanty and of marginal value --
I hope you will take a little time to consider your response so you
may add something of value rather than negative skepticism (positive

I'm skecptical as you don't understand even basic stellar and planetary
astronomy.

(say, 55 m/s) with 45kg mass remaining?

You get "atmospheric breaking" in a "basic astronomy" Class?

Some astronomy classes include orbital mechanics.

And some don't. One tool is worthless with out the nuts and bolts.

Then take a better class. If you think you're going to make deep insights with
no math skills you're sadly mistaken....

What makes you think I want to "make deep insights"?

Man (Boy) THAT is not on my schedule....




Well, Puddles, it has been entertaining and instructive discussing
asteroid impact dynamics with you... ;-)

You're still a loon.

You're still a closed minded bufoon,
but at least you don't use dirty words, chew tobaccy and spit.

Ah - because I don't buy into your pseudo-religous mumbo jumbo I'm closed
mindede BWAHAHA.


Without the "pseudo-religious mumbo-jumpo" THINK ABOUT THE MECHANICS
AND THE POSSIBILITY!!

You are "closed minded" because you will not consider an idea that was
not handed down to you from the heights of Mt Palomar! (or the chair
of the astronomy Dept.)

Tell me, Puddles, did any scientist EVER discover anything by refusing
to consider a new thought?

So you don't like the Idea! O.K., you have me convinced on that.

BUT YOU HAVE OFFERED NO CRITICAL OBJECTION!
All you have is -- "go take a class!"

Do you have any FACTS, or SCIENTIFICALLY VERIFIABLE DATA to prove the
possibility is impossible?

If you do, you certainly have not offered any.

SO IF YOU CAN NOT DEMONSTRATE HOW IT MIGHT WORK, THEN DEMONSTRATE THAT
IT IS SCIENTIFICALLY IMPOSSIBLE! (You can not.)



Now that we've got THAT detail out of the way....on to effects....


We were discussing the approach of a large cloud (or 'swarm') of small
asteroid bodies, and the expected effects.

There are, of course a nearly infinite number of directions. However,
an approach near the plane of the ecliptic (or galactic plane) seems
most reasonable. Four general directions seem likely: from behind, or
following, the direction of the sun's galactic orbit, or from ahead.
The approach may be from inside the central area of the galaxy, or
from outside moving inward.

You are very confused. Asteroids are planetary system bodies,

You are sufering from a closed mind. Someone TOLD you that "they
believe" asteroids are the result of planetary formation -- AND YOU
BELIEVED THAT and then closed your mind!

so why should
there be huge clouds of them in the galaxy not associated with stellar systems.
Also if they are orbiting in the plane of the galaxy, at the same distance as
the sun they would orbit at the same velocity = no threat.

Ah! that is the crux of the matter, now isn't it? They are not
"orbiting," they are "Falling" (relative to the earth's surface). They
are IN MOTION "other than" orbit!



If this cloud of asteroids approaches earth from the direction of the
sun, falling bodies would strike the dayside of earth. An approach
from the side away from sol would mean the falling bodies would strike
the night side of earth.


You should stop watching Armageddon

You should try entertaining an independent thought, rather than
parroting what you've been told to believe.



In either case, it seems likely that the approach of the asteroids
should be visible as they strike the planets between the cloud and the
sun, or between the cloud and the earth.

These mythical interstellar asteroids?

If they are "mythical" then when one falls on you, it won't hurt a
bit.



That is, if the cloud enters the solar system on the same side of the
sun as the earth, and crosses the orbits of the outer planets, the
impacts of those bodies should be visible to astronomers.

On the other hand, if the cloud enters the solar system on the side of
the sun away from the earth, then impacts on the outer planets should
still be visible to astronomers, and those that fall into the sun
would be visible during the day as comets.

So astronomers are "good" right now?

I've never suggested otherwise... Astronomers are people, some wear
pants and some wear skirts, and THAT does not make them either good or
not-good.

What has being able to see asteroids impact planets or fall into the
sun have to do with being "good"?



In either case, depending on the velocity of the swarm of asteroids,
the approach should be visible for some time, giving World Governments
and People some time for preparation.

Now listen, Puddles, I'm not asking anyone (you) to LIKE this idea,
and I'm not asking anyone to AGREE to the idea, I'm asking you to
CONSIDER the idea and THINK about it.

Its likelihood is around 10^{1001}.

Is that about equal to life forming in pond scum?

Fine: You don't like the idea, and you are NOT going to BELIEVE the
Idea....

Now that we've settled THAT, how about you spend some little time
explaining the math and orbital mechanics of small body impact on the
earth?



So far your input has been scanty and of marginal value --
I hope you will take a little time to consider your response so you
may add something of value rather than negative skepticism (positive
skepticism would be an improvement).


I'm skecptical as you don't understand even basic stellar and planetary
astronomy.

That's fine: skepticalism is not objectionable. What is counter-
productive is being skeptical and refusing to consider the details and
possibilities of an idea. Being skeptical AND considering an idea -
that is wise.

Agreed: I have, at best, an amateur or beginners concept of stellar
and planetary astronomy -- just enough to read "Sky and Telescope" and
say, "Wow, I wish I had a 10 incher like THAT!"

However, Puddles, THAT does not mean that I can NOT think, or imagine,
or CONCEIVE!



Any contribution would be greatly appreciated ;-)

owd

My suggestion is stop posting

Why, are you done thinking?

Hey, Look, Puddles; I didn't come on here attempting to tell you how
to run your science or career OR what to believe.

I posted my opinion, fine, if you don't lke that.... Oh, well....
You know what I believe, I know what you refuse to believe... fine.

Now I've posted an idea and asked for input....
If you don't like it -- fine... if you don't want to believe it...
fine.

Still, if you can offer some constructive skepticism, or consider the
idea as a 112 million to 1 impossibility, THEN explain the math and
mechanics... you would be making a constructive contribution....


---- 's been nice exchanging insults with ya... :-)


enjoy
