Ping!..................
This should be a cautionary tale for scientists everywhere. No matter how good you think your models are, reality trumps them every time.
This is solid evidence................no, wait.................
“The OSIRIS-REx team found a rough surface littered with boulders instead of the smooth, sandy beach they had expected based on observations from Earth- and space-based telescopes.”
But these same telescopes can accurately observe exoplanets and solar systems millions of light years from Earth. 😆
So drilling down 500 feet to plant the nuclear warhead would only require cans of compressed air?
Apparently so. The entire thing is held together by mutual attraction of their combined gravity wells..................
No kidding?
A hundred tons of solid rock hitting the atmosphere will scorch off a few tons on the way down, make a big sonic boom (think Chelyabinsk) thump into the ground and leave a smallish crater and local damage.
A hundred tons of gravel hitting the atmosphere will disintegrate and every single ounce of that hundred tons moving at tens of thousands of miles per hour will be exposed to static atmosphere at the same time, be frictionally super heated, flash from solid to white hot vapor. None of the solids will make it to the ground, but only as re-condensed pinheads of glassy rock. No crater.
On the other hand, the shock wave from all that energy released in a small space and time (think Tunguska) will flatten pretty much everything for 50 miles or more.
Of the thousands of exoplanets discovered so far, less than a dozen have been found using telescopes. The rest have relied upon other more indirect methods, and are typically hundreds or thousands of light years away, not millions.
As the asteroid approaches Earth, it will be pulled apart into a string of separate groups and individual rocks like the comet that struck Jupiter.
Hopefully they will mostly burn up as they enter the atmosphere........................
So Bennu is...fluffy?
Shoemaker-Levy broke up when it passed Jupiter, I don’t think there would be the same lateral Roche limit stresses on something coming straight in.
Spaceballs
Bennu probably isn’t as compacted as the comet was. It’s barely conglomerated..................
So, if it’s constantly ejecting matter, how has it been doing it for “billions” of years? To be doing that, it would have had to start at the size of a small planet, which of course means it would not have been able to become the loose collection of debris it is today....
Inquiring minds want to know!
It’s too small to have sufficient gravity to hold everything tightly together.
It needs Gravitas!....................

Good article. Thanks for posting.
