namatad: SlothB77: I always hear about astronomers gauging the likelihood something will hit earth.  What if something misses earth, but takes out our moon?  Wouldn't that be pretty bad for us too?  Tides and such as.

ROFL
the fact that you even ASK this question is a sign that the understanding of science in the world ... well most people are dumb.

1) "take out the moon" - let's break that down
a) take out = moon magically disappeared, no fragments. poof tides caused by the moon would go away. there would possibly be some residual oscillation, but that would quickly dampen. Quakes caused by this would probably not be an issue. life requiring the tides to survive would suffer. life requiring moonlight for breeding and what no would suffer.
but this would be the best case

b) take out = blow to pieces. well ... this would take a HUGE asteroid moving at a large delta-V. which we would already have seen and know was coming decades in advance. but going with the case
the pieces would SHATTER. some would go up and out, some would come down, some would form an AWESOME asteroid belt/ring around the earth for a rather long time. Satellites would become a thing of the past, along with the space station.

BUT, the pieces which rained down? well we would be farked. even a small percent hitting the earth would royally fark us.

2) the same tiny asteroid missing us but hitting the moon.
MEH
a) there would be moonquakes, which would have no impact on us
b) there would be ejecta, some of which would rain down on the earth, but we are talking much smaller pieces, smaller than the impacting asteroid, and in the end, meh
c) this would only be a problem for us if the impact was on the near side of the moon. if it were on the dark side of the moon, there would be the ringing of many alarms

tl;dr
nothing would happen to us


Why call people dumb when you just totally ignored what you were writing?

"nothing would happen to us" was your final conclusion yet in the three scenarios, two would affect us in quite negative ways.  That is opposite of your conclusion "nothing would happen to us".

Just because someone may be less informed but have a beautiful, quizzical mind doesn't mean they are stupid, it means they are asking to be taught.

I have never understood making fun of someone because they don't know something.  Especially if they are asking so they can learn.

Making fun of the deliberately uninformed, that's different.

Sure, but it takes a big man to admit he took a few college courses that were easy A's just so he could claim everyone else is stupid and mock naive questions.

namatad: It is estimated that there are more than a million near-Earth asteroids smaller than 100 meters
If it were to hit Earth in the distant future, it is estimated that it would produce the equivalent of 2.5 of TNT. The has been estimated at 3−20 megatons. Asteroids about 50 meters in diameter are expected to impact Earth once every 1200 years or so.

so pretty much nothing. esp since this thing is tiny and would almost certainly hit the ocean. well about 66% chance of miss.


it's estimated that you're a douche

I suppose that plenty of people here could ask scientific questions that you do not know the answer to, so by your very own reasoning you would be considered dumb, right?

dark side?

you mean the 'far side' that always faces away from earth but is alternately light and dark as it orbits the earth

WhoGAS: two would affect us in quite negative ways.


except that the likely hood of 1b happening is ~= zero
the chance of 2012 DA14 causing 1b is zero. (2012 DA14 is so tiny and moving so slow that it would have to hit a city directly to have an impact)
the chance of 2 happening and having an impact is tiny. the chance of  2012 DA14 hitting the moon and having any impact at all on the earth is zero.

/for all values of zero other than the pendant version of NOT ZERO JUST so close to zero to be functionally equiv, but you cant call it zero)
/but go ahead and argue that you mean affect as in if it is possible, no matter how vanishingly small
/strangely enough the dino-civilizations thought the same thing right beforechicxulub hit the earth.

No. That isn't going to happen. There just aren't that many thing that are that big in the Solar System anymore.

Mugato: Why are people so obsessed with the end the world? It's too bad that your life sucks so much that you're praying for the end of the world but it's not going to happen. Not until the sun burns out and that's a period of time that neither you nor I can comprehend. So farking relax about the end of the world and if you're looking forward to it so much, just kill yourself and get it over with.


It is a virtual certainty that life on earth will be catastrophically devastated by an asteroid impact long before the sun burns out.

Assuming, of course, we don't bother to worry about such things and make no effort to plan for them.
