Will asteroid Apophis impact on earth later upcoming month octber 2020 or it will be safely flyby the earth??? Hw much we r safe frm this asteroids???
Better pack your bags now then!Apophis is due to pass by earth and then be on its way around the sun in 2029/2030. It will come back in 2036 and is expected to plummet into the Pacific Ocean. Hawaii will be a devastating loss along with extensive damage to the west coast of the United States.
So says Neil deGrass Tyson in his book;
- Death by Black Hole; pages 261-262
Supposedly, everybody who knows something about this isn't saying much.
The likelihood of a big one happening in our lifetimes is very small. Not zero, but small. We've winged it for the entire existence of homo sapiens as a species so far, so I'm not losing sleep over it.I am not convinced. See #6.
At least I think the virus will get me before the NEO.
Better still - neither

Yes, and a few years ago there were two that zipped by unannounced at almost the same hour, IIRC. They weren't together, surprisingly, because they came from different directions.What concerns me most is not the thousands or tens of thousands of known objects (do you know how many NEOs there are?) but those we do not know about. Many of these are of low albedo and, when coming 'out of the Sun' stand zero chance of being seen in time. I remember around 1992 or 1994 (IIRC) there was one close miss, then the same day there was a total unknown (out of the Sun) which was not seen until it had passed us.
We do get a break from excessive risks from these since they aren't likely approaching us from along the ecliptic plane.As for the very long orbit objects or interstellar ones, that have no known prior passes to deduce any orbit from - these are uncommon enough to be a much less likely danger than the NEO's orbiting within the solar system, but will represent a far greater challenge to find and track in a timely manner.
I was surprised to learn that bio hazards are also two dimensional - CFR and Ro, but this isn't a Covid thread. I learned about it because I asked a doctor if there was something similar to the Torino scale.I am not convinced. See #6.

There have been pairs since. Here is an article of two passing us in 2010 and within about 12 hours of each other. But I think the one I recall was more recent still.Yes, and a few years ago there were two that zipped by unannounced at almost the same hour, IIRC.

I think we are talking about the same two. I'd guess around 1992-4.
One clever argument for a defense is that the dinosaurs had none.Developing and entrenching a lasting civilisation that can do meteor defense over very long time scales - longer than any civilisations have ever lasted - is essential to making meteor defense effective. If we don't achieve that we won't get the meteor defense.
