Perusing my Google news feed, I come upon a rather scary science article headline:
Asteroid to come within 30,000 feet of Earth’s surface next week
So, Asteroid 2012 TC4 will approach Earth so closely it’ll enter the atmosphere (at that altitude, even down to the troposphere, below the cruising altitude of jet airliners). And somehow won’t cause a huge and newsworthy event.
Of course, the article itself is just a little different:
Oh, “miles”. Not “feet”. A very close approach, but not a Chelyabinsk event. :rolleyes:
Stupid headline. I’m not sure what “The Voice” is (in journalism), but their headline writer needs to be… something. Counseled. Shot. Whatever.
Media’s always been stupid about anything scincey.
Feet, miles, same thing, really. If you aren’t aware of how orbits and such work, then one doesn’t seem any more or less reasonable than the other. While 30,000 feet is well within the atmosphere, I bet half the editors in the room did not know that.
Indeed, now that I’ve gotten over my annoyance at that brain-damaged headline. That’s in the same general neighborhood as a standard geostationary orbit (22,500 miles).:eek:
In other words, it’s going to be passing close enough to a bunch of satellites we care about that it could yell “howdy” in passing. (Except for being a non-yelling rock, and in the soundproof vacuum of space, of course.)
After a similar close fly-by a few years ago, CBS radio pundit Dave Ross remarked, with a tone of great exasperation:
“. . . comet [or asteroid or whatever] came within 30,000 miles of Washington D. C. and missed !”
In the other extreme, there was a headline not too long ago about a “dangerously close approach” by an asteroid - with the stated distance of 140,000,000 miles! The sun is closer than that, people!
I think they added about three extra zeroes. I wish I could find that one.
Not that scary. 10-30m asteroid is about the same size as the Chelyabinsk meteor, and significantly smaller than Tunguska. As scary natural phenomena go, it doesn’t hold a candle to several events of the last couple months.
The Chelyabinsk meteor was as powerful as a modern strategic nuke. (Estimated 400-500 kilotons.) If it hit a city directly, and exploded at lower altitude or on the ground, it could kill a lot of people.
Well, we did just have a meteor so impressive that the RT headline begins “Great Ball of Fire!” Where? Oh yeah, it lit the sky over Shangri-La. Shangri-fucking-La, people. This is a bad sign.
And, if the original headline weren’t so gut-bustingly wrong, it would have gotten to lower altitude. The Chelyabinsk airburst was about 97,000 feet. This meteor was predicted to get down to an altitude less than 1/3 that. OW.
But they didn’t fix the mistake. The article still says 145 million miles, which is almost the closest approach of earth to the asteroid belt itself. It was actually 4.4 million miles. I don’t know anyway 4.4 million can be accidentally converted to 145 million by any typo known to man.
