Surprising Recent Discoveries of Three Large Near-Earth Objects

If they can detect the orbit, and see that it is obviously not aimed right at earth, why the "potentially hazardous" rating?

Orbits can change over time especially if they are not stable like the planets or comets. All bodies in space are subject to encounters with other objects that can subtly change their orbit, even without hitting them.

The sun could also heat up a patch of frozen stuff on it and turn it into a little jet, shoving it out of its orbit.

We're all DOOMED...................DOOMED I tell ya.

Well, we've had a good run. Lots of fightin' and lovin' and choppin' down trees and stuff.

Sure will look cool, though, when it comes sailing across the sky all bright and blazing and then superheats the atmosphere into a huge shockwave that flattens half the planet and then fills up the sky with clouds until everything dies.

KAH-BOOOOM!!

Warning Warning Danger Will Robinson Danger lol, hopefully it hits my house so I don't feel a thing lol.

Even if they don't strike Earth, their orbit seems awfully close to ours.

Millions of miles away is all well and good...but they have to cross and go through the asteroid belt...a 20km asteroid has the potential to create havok as it transits through the belt, if it dislodges some of the asteroids from the belt, there's a real danger some might be knocked right into us.

How could these have been missed though?

I'm sure i saw a NASA spokesperson claiming they had discovered all of the large NEO's that might be dangerous to us, and that only the small stuff was unknown.

IOW, take what the experts say with a pinch of salt, they obviously don't know.

You have to understand that 2 miles, 10 miles, even 100 miles across is tiny in space. Think about driving 100 miles from your home and where that is. Now think of viewing that trip on google maps. Start demagnifying your view and the further away you get the smaller and smaller 100 miles becomes. Earth is nearly 8000 miles in diameter. Of course a 2 mile wide asteroid hitting earth would cause some major damage, but when comparing it to the size of space, its nearly nothing in size.

In the astroid belt, most of the asteroids are tiny. Like very small. In fact some are just little pebbles and the largest is like 600 miles in diameter, which is the exception not the rule. These millions of asteroids are spread out over a vast area. It isn't like a video game or movie where they are all bunched on top of each other. They are so far apart you likely couldn't see your neighbor if you stood on one without a telescope.

The point is, not likely an asteroid a mile or 2 wide will travel to the asteroid belt, hit another asteroid that is not to small to be shattered and not too big to budge, and then it have a direct path to hit earth. Certainly it can happen, and likely has happened before, the odds are far against it.

Wow pretty dismissive, tell that to the people in Russia that just got hit lol. It does not have to be big to do major damage. Ison and enke both went through the android belt. We have no idea yet how many or what could be headed our way.

There is talk that ison has a unique carbon composite that could react violently with our atmosphere. Ison is also significantly larger than what nasa estimated. It is going to be interesting to see if it survives the trip around the sun and what the path or paths are when it does.

I think the next month should be interesting. Watch the sky lol.

I wasn't dismissive about the damage it would do if it hit earth, I was only suggesting that a 2 mile wide asteroid isn't that likely to hit another asteroid in the asteroid belt that would cause it to deflect toward earth. Of course a 2 mile wide asteroid would cause absolute massive damage on earth.

Thanks for the update! Would love to see one myself.

Thanks for posting this Cheesy
Interesting times to watch the sky we'll be living

This smells like Werner Von Braun's statements " After terrorism comes Asteroids they gonna build space based weapons to shoot asteroids and the final card..." well some of us know what the final card played was..

I'm still waiting for more proof than one person's word that he said that. But asteroids have been a threat since the dinosaurs (obviously). The only difference now is that there are more people looking up and noticing them.

Well it is clear to me that NASA
will NOT tel the public ANY thing about comets or asteroid
that could be a danger to earth.

that is IF they can detect any thing in space.
I bet itis a big lye that the can detect objects in earth orbit.
NORAD is just to get more money for nothing?

they can not see some thing 19 miles across!!!

I am not saying that they can not follow objects that they KNOW of.
I am saying that they can NOT find new objects.
they probable have 10 detectors that can find some!
and only in a small space.

they can detect Low orbit objects.
but Not in space.

NORAD's job isn't to find asteroids of any size. That's NASA and other civilian space agencies, like the ESA.

In case it were effected by external forces (gravitational or otherwise) plus the margin for error.

None of these seems to be too dangerously close. We have had some come between the Earth and the Moon in the last few years. Those are the ones I consider close.

Yep yep, although they have assets that could be tasked to help if they wanted to. Nasa did reactivate WISELY to look for objects. They can find them they are just not telling the truth. Take ison, according to them it is small and no threat, lies. They know the opposite, it is huge, massive. It is also big danger to us. This thing is massive and it is effecting the sun. Flares are getting more active and are firing at ison.

One hit ison and stripped part of the tail spreading it out significantly. In other words if it makes it around the sun part of this tail will hit us and depending how bad ison fractures and splits us we could see a bullet to the heart so to speak.

I am not trying to yell doom porn, I am saying we do face real danger here and nasa has straight up lied about it.

Firstly, if there were a hazardous object on a crash course with the earth, NASA wouldn't be able to hide it. There are thousands of amateur astronomers out there that would spot it and they would let the cat out of the bag. NASA gets far too much credit in that regard; most objects are in fact discovered by amateurs and private observatories, and not by NASA, as many mistakenly believe.

Secondly, the flares are happening because we are in solar maximum and it has nothing to do with ISON. Comets all heat up and react as they near the sun, ISON is no exception.

I agree they can't keep the cat out of the bag, but problem is many people look to them alone for their answers and warnings thinking nasa still working for the people lol. They are giving disinfo and not warning people.

I have been watching this with several watch groups and it is disturbing. Yes we are in solar maximus but ison is also influencing flare activity as it approaches it's run around. Ison built up huge electrical differential that was partly stripped away when it took direct hit from an x flare. This tripped ison of much of it's electrical potential and scaled back it's tail. This could cause us harm because it significantly widened the tail and spread out degree. The closer it gets you can see the sun reacting on the right side as it is coming in.

Ison is very much larger and potentionally more dangerous than nasa is warning. We should watch close through thanksgiving when it comes around the sun. December and January should be very intersting.

Be safe

Do you have sources for any of that?

And, I don't mean youtube videos.

8,000 miles in diameter?????? I think you need to fact check.
