From my perspective. the first step in creating a comprehensive defense of this planet would be to remove the debris field surrounding it. All the junk floating in near-earth orbits poses an impact hazard to the infrared satellites that are needed to observe distant objects effectively. Once monitoring satellites are in place a defense reaction force could be deployed to employ available methods of diverting or destroying any asteroids or meteorites that become a threat.
It seems that the comments have taken a derisive turn instead of attempting to provide constructive input. Disappointing. However, the attitudes prevailing explain why the comments are ignored.
Nobody ever made a prediction of Apophis' orbit corrected for the Yarkovsky effect. What they're probably doing is predicting the orbit from a least-squares method-of-Gauss algorithm that gives equal weight to all of the observations. That could be misleading, since the Yarkovsky effect, acting over time, would make the precise orbit non-Keplerian. Long-ago observations of Apophis from the archives would be the least reliable for use in predicting the asteroid's future path, and, indeed, their use might lead to worse predictions instead of better ones. The Yarkovsky effect is a small acceleration due to the differential radiation of heat from a spinning asteroid.
No but I believe it’s because it was classified as too small to be an epoch creation object. I don’t think we should be worried about NASA not tracking mass extinction capable space objects. But again I’m no expert or even an informed amateur astronomer
It's a good point indeed, I wonder how much larger it would need to have been for it to have been noticed heading our way in significant enough time in advance, as this could be a big deal one day.
It was small indeed but its because it came from the direction of the sun and not the night sky. A bright moon at night reduces the visibility and amount telescopes can see. So the sun which drowns out even the relatively bright moon reduces observability down to nothing but the sun. Weve actually spotted smaller with an 18 hour warning. Not sure warning we would have got from that Russian asteroid, but since it was the biggest thing to hit us in 20 years im guessing we would have got a day or two warning at least if it had come from our night sky instead
Theyre the first step. If we had a full proper system to detect all asteroids/comets, we could hopefully detect problem asteroids, 100s, or even 1000s of years before they hit. Our only real problem then would be asteroids/comets which come from outside of the solar system. But again a proper system should be able to detect any sizable objects up to 100 AU (100x the distance of Earth to the Sun) which would give us years to act/prepare.
45:00 Proof that Amy is hot ;-) Radar of that asteroid looked a lot like the comet Rosetta visited, sort of rubber duck shaped. Maybe also a contact binary?
Apocalyptic scripture regarding a large boulder the size of a large milestone being thrown into the sea. Read Revelation chapter 18. The boulder is spoken of in 18:21-24. If it's been foretold, nothing will stop it.
Hey NASA. I think the key to asteroid discovery would be to know where they are coming from. (ANSWER) = Think of Jupiter's giant red spot as an exit wound from a high velocity projectile in which all the periodic comets and moons thereof were born and as the lesser velocity projectiles return to where they were born pass through this hole in Jupiter tearing off more and more chunks of debris casting out into spaces vacuum at lesser velocities these asteroids which go towards the Sun and upon impacting the Sun's surface burn up and cast out massive solar flares. (IT"S CALLED FEEDING THE SUN). Anyways after 75K years the spindle of Jupiter has been ripped down to about 1/5 the size of the diameter of the equator.

i am biggest fan of this page
I love latency problems

Man, love the 90's soundtrack! Where can I pick these beats up?
Very interesting!
Space boulders everyone, we've got to watch out.

Did we know that Russian one was coming? Seems like no. :-(

8:50, 50:50 from my understanding such cases they communicate with the government, which hopefully should inform the public.
57:14 ...i think they've just informed us.
All we Gotta Do is make the Ship from the Asteroids Game that Obliterates Asteroids with it's Crazy little Laser thing & we're Good! XD

Telescopes aren't really planetary defense, they are just asteroid detectors

Early detection is crucial. The sooner you detect a dangerous asteroid, the longer you will have to prepare a mission to deal with it.

I know detection is important, but the thing that is actually defending you is the mission
