Latest Earth-Crossing Asteroid Passes by Tonight
jc42 writes "Astronomers have been looking at the first images of asteroid 2007 TU24, the 250-meter asteroid that will pass 540,000 km from the Earth at 8:33 UTC (3:30 EST) Tuesday morning. So get your telescopes out; it's a 10th-magnitude object. Or just hold your breath as the time approaches. It might be sobering to consider that it was just discovered last October, and we know about maybe half of the objects like this in Earth-crossing orbits."
Or maybe we know about ALL the objects like this now. That's the way it is with a word like "maybe".

The problem is that when you say something is 540,000km away, the huge general population tunes out. That's an ASTRONOMICAL number by most considerations, so nobody gives two shits. Except, as it turns out, we're dealing with astronomy, so astronomical numbers are the norm. The fact that nobody is really considering funding a worldwide effort to try and map all the objects that could potentially cause a major threat is disturbing. Hillary voted for $1 Million for a Woodstock museum - doesn't it make more sense to fund a huge, cheap project that could potentially help save the entire Earth from annihilation than a museum about a rockin' sex-fest? The latter doesn't really seem up most of congress' alley, but yet they vote that way.
NASA needs to spearhead projects that are useful, in collaboration with the rest of the space-viewing world. The fact that there isn't a loud voice shouting about this concept to the pols is embarrassing.

At least this one is outside the lunar orbit. I seem to recall one a while ago that was much closer.
A quick Google says that lunar orbit is about 385 MM (mega meters), and this is 540 MM. (Why don't we use megameters when we're rounding to the nearest 1000 km? We have all these nice metric units; let's use them!)
nevermind that huge chunk of unstoppable space-rock heading right for us...if it mattered, we'd know by now, right? riiiiiiight.

I'm so elated that there's an item on the front page that isn't tagged "whatcouldpossiblygowrong", my head could EXPLO***spaf***
Isn't that what one is supposed to do during this sort of celestial event?
Cut him some slack. He said "maybe half" which technically means you're not allowed to pin that down to an actual number. After all, this is the internet -- the magical place where, in lieu of hard facts, you can just make shit up.

Don't bother holding your breath. At magnitude 10.3 it's too dim to see without a telescope to gather extra light. By a factor of 50 or so (even on a clear dark sky).

Think real hard about this now. We've had a comet smack into Jupiter not too long ago, leaving lasting marks. We've had smaller objects hit the earth before, like the Tunguska event. Hello? Hint?
It was nice knowing us!

Does anyone have a link to a page showing where the asteroid will be in the sky and at what time? Hopefully the clouds will clear here and I can get a glimpse of it through my telescope. I think 10x50 binoculars can only get you to magnitude 9, but I think my 8" dob can get me to 12th magnitude...
- 10th magnitude? A bit of a reach for my 90mm scope, especially with light pollution.
- Forecast is cloudy with rain/snow. Won't see the sky anyway.
- I live in Minnesota and it's January -- c-c-c-c-old!
- 2:30am CST on a weeknight? I have a job! That's past my bedtime.
I did catch an asteroid once, and it was kinda cool. Using a map of the asteroid's path, I set up the scope on some recognizable stars and waited for it. It looked like a faint speck moving against the background. Not sure it's worth the trouble for a second look.I might be indecisive, but I'm not really sure. What do you think?
Watch The Last Train, if something like this hit us it's game over.
I could get on with the raping and looting.

Is there anything that could be done to stop an impact if we were to see one coming? Aside from sending Bruce Willis up in a pair of Space Shuttles, of course. What's the value of having an accurate map?

we have had events and observations that tell us that it will happen someday.
To say we have had 'warnings' implies there is some cosmic goat trying to tell us something. There is not, there is only a group of animals aware enough to consider long term and far away events and how they impacts us.
