I heard a TV news teaser two days ago that mentioned something about an asteroid coming close to the earth recently. Haven't heard anything about it since. Near is a relative term. I assume the odds a good-sized asteroid striking the earth in the near future is (ahem) astronomical. Does any space organization watch for such things? or is it not worth bothering about? #mike (sun!mae), M/S 8-40 #"There's nothing human that's alien to us." - A. Einstein

That is, amazingly close in the overall scope of the universe. 500 million miles close. The article described that distance as twice the distance of the moon to earth. I don't recall the article giving dimensions of the asteroid, but it must have been exceptionally large for scientists <sp?> to even have noticed it. -- ==dan=hinojosa================================================================== email - uunet!ucsd!hp-sdd!hinojosa \ / uunet!hplabs!hp-sdd!hinojosa --------------------------------------- ---==(*o*)==--- ---------------------- Jesus saves... but Gretzky gets the rebound!

It also indicates that we would be lucky to get one days warning (let alone enough time to break it up or redirect it.) Furthermore, it will make another close pass in about 30 (?) more years.

I heard that at its closest, its distance was twice that of the moon. That's actually pretty close on a cosmic scale. They also didn't see it approaching---I think they didn't spot it until it was at its closest distance (or maybe after). So what's this doing in sci.space.SHUTTLE, anyway?

Experts estimate that if it had hit the earth, it would have had a total destructive force of 20,000 (1 megaton) nuclear bombs, leaving a crater 5 miles deep, and 10 miles across. If it had landed in the ocean, some serious tidal waves could be expected. The asteroid was not sighted as it passed, but was discovered on photographic plates. It is believed that it will pass this way again, and again. --------------------------------------------------------------------------- sl161011@silver.UUCP Kevin B.

I don't recall the article giving dimensions of the asteroid, 500 000 miles. 500 000 000 miles is more like the closest the earth gets to jupiter, or maybe saturn, I forget. -- John H.
