Astronomers have lost track of nearly 900 asteroids.

"Astronomers have lost track of nearly 900 asteroids that could be on a deadly collision course with Earth"

How on earth (no pun intended! ) could they have lost track of them? I mean, to lose one asteroid may be regarded as a misfortune; to lose nearly 900 looks like carelessness. Is there nothing NASA can say that you anoraks won't believe?

How can they 'track' something in deep space which is travelling at nearly 30.000mph? Do you understand how fast that is?? This isn't 'science', it's fake science, and you know it.

"an asteroid that is travelling at 28,000mph towards the earth, it emerged today."

If they cant track it why did you accept the science about the speed it was travelling?

 

It's speed isn't cosmological science, it is proven kinetic physics; the question is - at that phenomenal speed, how can anyone expect it to be within passing visual range for more than a few seconds.

 

How did you calculate the speed of an object in space after you asked how it can be tracked? Im curious to see your science.

 

The same reason you can watch jet aircraft flying high overhead even though they’re travelling at hundreds of miles an hour and that you can see stars in the same patch of sky that are many light-years apart. The further the object is away from you, the wider the distance within your field of view.

 

"64,000 mph asteroid was fastest on record"

The photo quite clearly shows the asteroid in a 'now you seen it, now you don't' kind of way. So is it any wonder the 'scientists', lost track of it? By the time their radio telescopes locate it again, after it re-emerges into visibility beyond the curvature of the earth, at that speed it would be at least 3 light years away?

 

I clearly asked you how you calculated the speed of an object in space without being able to track it. Please explain

 

For STARTERS near earth orbit is NOT "deep space".

Secondly it is only possible to track the LIGHT REFLECTED from the object. If it passes into a shadow it will effectively "disappear".

If you look up into the night sky and see a meteor flash can you track where it is going to end up from that single observation? Do you know if it is big enough to survive and hit the earth or will it burn up in the atmosphere or if it is going fast enough to "bounce off" on another trajectory into space?

In essence these objects are akin to meteor flashes because by the time the alert is given they are already out of visual range for subsequent tracking sightings. You would know this if you had actually bothered to read and understand the article you quoted.

What this highlights is that we effectively need more telescopes with automatic linking so that when the first telescope records the initial observation the other telescopes will be able to look for it in the probable predicted locations immediately.

Cosmology is a developing science. We are still learning how to do these things. Why do you fallaciously assume that everything must be working 100% perfectly all of the time when it comes to science?

 

I have a little experiment for you. Watch an Indy car race on TV to see who wins. Now go to a race track and watch a car go past you.

Is it easier to see the car from far away than close up?

Look up in the sky at night during a meteor shower. When you see a shooting star how fast do you think it was going?

You saw it anyway didn't you.

 

Maybe you should put the UKSA on it, I mean they have done so much for the advancement of space travel and have so many discoveries and accomplishments . The UKSA has long glorious history going all the way back to 2010.

 

"Organisations like Nasa track thousands of them to ensure they don't hit Earth." Quoted from the link and that's Pure D Bullshat.

They track asteroids but there ain't jack they can do about them. Entropy is going to get us one way or another.

 

Depending on the time frame and composition it is likely an effort would be made to divert or destroy an impending asteroid impact. The results however would be anyones guess.

 

Come on now, they can't even stop Kim's nukes.

 

You literally just said that since you can't understand it, there's no way it can be true.

 

It's just rocks. They must be hard to see.

 

Had Lil' Kimmy ever fired a Nuke we might perhaps know if you are correct, fortunately he has not. Had we ever detected an impactor we might see if I am. Until either occurs everything is speculation.

 

Well, they are tracking 15,000 near earth objects and finding new ones at the rate of about 500 per year.

Losing track of some for some period of time doesn't really seem that ridiculous given their number, their size and the limited attention we're willing to fund.

And, your math is sadly lacking. Except for incredibly rare incidents, these objects aren't leaving our solar system, let alone traveling 3 light years away.

 

There are several known strategies for diverting an asteroid.

The question is whether we detect the collision in time. We would need to determine the best solution and then design and launch a vehicle to do the work.

That is likely to take a number of years, so the first real trick is early detection and tracking.

 

How the hell do you think that I could have calculated it; and what means do you think are available to me to track one? I averaged the rate of travel from a few legit-sounding search results. Out of curiosity, what do you believe is the speed of an asteroid? And please explain your conclusion.

 

Which is much easier said than done? I think you've been watching too many 'There's an asteroid headed straight for us and the Earth is doomed unless Kirk Douglas can divert it in some way, and in the nick of time before we're all agonner'?

 

They're all charlatans whichever space agency they work for. Wish that I could get a piece of the action - money for old rope and a job for life?

 

Of course not, and it begs the obvious question (well it's obvious to some of us ) 'So what's the point of tracking them even if it were feasible?' Answer - it's all grist to the mill for the boys of the space industry!

 

And your source for all that er, interesting information is? Don't tell me, I already know . . . NASA.

 

oh I dont play a scientist on the internet, I am one in real life. Good to see your back to trusting science to get you speeds..However Im curious as to why you accepted those results if you dont think scientists can track them. Can you explain to us how your scientists calculated those speeds without being able to track them? Again its your science...Im trying to learn it.
