I understand that Apophis is a composite asteroid. What do you think are the chances that it will shed parts of itself when it passes by in 2029?
Some researchers were wondering what effect Earth's gravity would have on asteroid Apophis when it passes by in 2029 and which poses no threat of impacting Earth. They ran a computer model based on the asumption that Apophis is composed of a mass of rocks loosely held together by gravity rather than being a single rock. Based on the computer simulation, the most that might happen is that Earth's gravity could cause Apophis to ''experience slow, gentle landslides, as smaller loose rocks moved along its surface.''
Asteroid Apophis could experience landslides when it passes near Earth
''Phys.org) —A team of space scientists with members from the U.S., China and France has found via computer modeling that an asteroid due to pass close to Earth in 2029 is likely to experience minor landslides. In their paper published in the journal Icarus, the researchers describe the data they input into their model and what the simulation showed.''
''The simulation showed that it was likely that Apophis would experience slow, gentle landslides, as smaller loose rocks moved along its surface. And if that happens, it would offer scientists observing the asteroid some new information about its age.''

Thanks for the link. I normally don't concern myself with such trivialities, but with all the buzz I hear, especially from the anti-preppers that frequent this forum, I was kinda curious about that asteroid, and I think another, that they are infatuated with. They seem to think such trivialities will alter our outlook on prepping ...
This will not change how much I am able to, or choose to prepare. It is always wise to be prepared. For example, I can't stand people that think it's unfashionable to carry jumper cables in the trunk, then they cry when they get stuck.
Anyway, there is no prepping for a meteor strike except to get out of its' expected impact area. What we know currently is it is roughly the size of a stadium. If it hits land, there will be about a 200 mile diameter of flat, burnt ground but, this is not big enough to shroud the atmosphere in dirt and dust and mess up the whole world and, there is a 66% chance it could land harmlessly in the drink.

I agree with what you posted, except, how many cubic miles
of water would it vaporize if it hit in the ocean?
People today whine about climate change, and pretend it has
something to do with us burning coal, wonder what they will
whine about if this hits?
(and where would the tsunami be felt?)
