<p>Ok, the Earth has meteor showers by drifting into the debris of a comet left&nbsp;over from the tail&nbsp;right? Well, wouldn't the moon get impacted too because we drag it through the tail with us and it doesn't have an atmosphere? If so, would it be possible to see an impact on the moon during a meteor shower?</p><p>I'm just curious why we never hear of any impacts on the moon during showers.</p> <div class="Discussion_UserSignature"> <font color="#0000ff"><p style="margin-top:0in;margin-left:0in;margin-right:0in" class="MsoNormal"><font face="Times New Roman" size="3" color="#0000ff">What ever happens, happens/</font><font face="Times New Roman"><font color="#0000ff"><font size="3">Just call me Phoenix</font></font></font></p></font> </div>

The reason we don't hear about them in the popular press is that they are very faint, too faint to be noticed without a telecope focused on the moon.

<p>Here's the NASA web site that tracks lunar meteor impacts:</p><p>http://www.nasa.gov/centers/marshall/news/lunar/</p><p>They are only listed if they are detected on more than one telescope, since with only a single scope and CCD detector, the flash would be just as likely to be a cosmic ray on the CCD detector. Confirmation from two different scopes and detectors ensures that it really is a lunar meteoroid impact. (since by definition, the moon can not have a meteor as it has no atmosphere, it can only have a meteoroid impact).</p><p>As you can see, the detection rate is&nbsp;fairly low, about 7 per month.</p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

This is quite interesting because i've always thought, wouldn't you be unlucky if you got hit by one while on the moon. I mean, I know the probability is remote, but it is much more of a possibility than on Earth due to the atmosphere being almost non existent. Scare the crap out of me, the thought of being stood on the moon and looking at HOME from all that distance away. Cool, surreal but scary as heck! :) <div class="Discussion_UserSignature"> <strong><em>In an infinite Universe, any point can be said to be the centre as there are an infinite number of stars either side of that point... ;)</em></strong> </div>

I think a move I saw a long while ago had this occur during a space walk. I dont remember the name of the movie. Its the one where humans are actually exploring Mars and their little AI Rover type thing goes MIA as it starts thinking for itaelf and actually targeting and chasing the astronauts. Anyway, in a scene in that movie somewhere one of the astronauts gets some micro-meteoroids bust his suit and flesh for that matter. What WOULD actually happen if a space suit was breached like that in such a quick yet I suppose relativley small hole?</p><p>&nbsp;</p> <div class="Discussion_UserSignature"> <strong><em>In an infinite Universe, any point can be said to be the centre as there are an infinite number of stars either side of that point... ;)</em></strong> </div>
