How do we know it's not being sent here by those arachnids?

Oh No! Will this affect my trip to Punta Cana this weekend?

They have plenty of rough necks sitting at home ready to drill so no worries.

The only devastation that could potentially cause is to Elon Musk’s car.

lets hope if there's a bigger one headed towards earth we'll get a little more of a heads up

The same G force that "blows to, smithereens" space junk etc. that comes back to earth?

Still think it's unlikely G forces would rip a 130 ft solid chunk of rock apart.

No. It’s only 130 ft wide and would burn up in the Earth’s atmosphere.
The Chelyabinsk meteor that hit Russia in 2013 was approx 65 feet wide and the air burst damaged like 7000 buildings (mostly broken glass)

What exactly happens depends on the composition, but something that size isn't much to worry about.

And if it struck at a different angle it could have been much more devastating

Would it’s orbit have been slightly different somewhere on Earth would be really screwed.
Statistically speaking, It would have landed in either the water, an asian country, or in afria. No care.

Not really. I just looked up a simulation of a 100 meter asteroid impact (i.e. more than double of that asteroid before entering the atmosphere) and the results were on par with a Category 5 earthquake. Those happen at least 3 times a day on Earth.

It's like the old saying, you can drop a mouse down a 1000 foot mine shaft, and he will get up dazed but walk away. A rat dies, a man is broken, a horse splashes.
I think in general, if the object is small enough that the atmosphere doesn't tear it apart or burn it up completely, then it's small enough to not cause catastrophic damage. Larger objects break apart more easily and actually have a smaller chance of affecting the surface of the earth. It requires a really, really large object to get broken up and the remaining chunks are still large enough to cause major damage.

The one that hit Chelyabinsk Russia in 2013 was the equivalent of a 400-500 Kiloton nuclear weapon. This one is estimated to be larger. If it hid a populated area the effect would be catastrophic. For comparison, the Little Boy bomb on Hiroshima was 15 Kilotons. This asteroid would completely obliterate any city it impacted.

This article says that an 800kiloton weapon hitting midtown Manhattan would destroy everything in a 90-152 square mile area.
