The locals do that for amusement and free air conditioning...

Can I presume that they always have an eye to the sky? Or, do they take the attitude of "World According to Garp" - if a meteor hit a town once, the chance of it EVER happening again is absolute zer0.

I believe they would keep it top secret if they did see a big one headed our way...

Yep, they'd make up some story that it crashed harmlessly into the ocean, much like the story about Bin Laden "crashing into the ocean".

This article was posted from space.com.
//////////////////////////////////////////////
The 150-foot-wide space rock will pass within 17,000 miles (27,000 kilometers) of us next February. That’s nearer than the orbits of some geosynchronous satellites
///////////////////////////////////////////
all geosync satellites are at 36,000 miles. You would think that someone writing for space.com would get at least the simple things correct.

Can we bribe the asteroid to do a quick turn so there’s no warning?

Really? For someone making such a comment you might want to get YOUR facts right.

OK Code toad!!! 36,000km and 26,000 miles is that better?

Jeeez I mix up my KMs and miles. the world is going to end. oh my.....oh my......woe is me

Meteor crater in Arizona was formed by an object that same size. It's impact force was equivalent to 10 megatons or >600 Hiroshima bombs. I'd say anything living in that area had a pretty bad day.

Beat me. I was going to post the same. I visited Barringer crater years ago. I remember having one of those irrational reactions of looking back up to the sky. A kind of paranoia. Later, my entire group admitted to the same reaction.

“150 feet across is not even very big. Not dangerous at all unless it lands nearly on top of you. Well, within a mile maybe.”

Depends if that is the size in space or the size of what hits the ground.

Meteor Crater in Arizona was formed by a meteor about 150’ diameter.

Wouldn’t have wanted to be very near when that puppy impacted.

It will happen. We know that for a fact. There will be a large asteroid strike in the future. There is one out there right now with our number on it. It has happened at least 6 times in the past. Most likely we will develop the tech to stop one from hitting us before too much longer though, unless all these damned socialists take us into another dark age.

“I climbed part of the way down into the crater when I visited. From what I remember, I heard that Apollo astronauts trained at this crater before their moon missions.”

True story.

It’s not even 26,000 miles. Even with Internet searching you can’t get that fact right? Come on, you were the one complaining about facts.

A lot depends on it’s angle, a glancing blow might only
result in a Tunguska type explosion, if on the other
hand it came in steeply, the atmosphere might not do
much to it.

Yep sure wouldn’t want to be within many miles of it.

I posted on #51, by the way, that semi synchronous could be considered geosynchronous, like Obi-Wan says, “from a certain point of view”.

It’s 26,000 miles semi major axis, not altitude.

Another reason to prep. This one may miss us, but there are others that won’t . . .

That is a really good question. Any time I have had significant insider information about a news story, there were major chunks of the report that were wrong or misleading.

//////////////////////////////////////////////////////////

A geostationary orbit (GEO) is a circular geosynchronous orbit in the plane of the Earth’s equator with a radius of approximately 42,164 km (26,199 mi) (measured from the center of the Earth). If you insist on altitude from mean sea level then its 22,236 miles.

MY son is a for real rocket scientist. He and all his peers round of to the nearest k in either miles or KM. The only time they would figure the 199 is never because the 26,199 is only an approximation due to gravity anomalies encountered as a satellite passes over the earth. Figuring an orbit is very difficult. The wiki article leaves out a lot.

And your problem is?
