Greetings to all!

Anybody like Iridium? Let's talk about meteorites.

Anybody ever XRF meteorites? Let's talk about meteorites.

Anybody want to talk about possible global extinction? Let's talk about the year 2185, Bennu "the Asteroid", and all of the "primordial molecules" it contains.

Peace and health,
James

Welcome James! Do they actually know what Bennu has in it exactly?

101955 Bennu​

Bennu asteroid reveals its contents to scientists − and clues to how the building blocks of life on Earth may have been seeded:​

101955 Bennu (provisional designation 1999 RQ36) is a carbonaceous asteroid in the Apollo group discovered by the LINEAR Project on 11 September 1999. It is a potentially hazardous object that is listed on the Sentry Risk Table and has the third highest cumulative rating on the Palermo Technical Impact Hazard Scale.[9] It has a cumulative 1-in-1,750 chance of impacting Earth between 2178 and 2290 with the greatest risk being on 24 September 2182.[10][11] It is named after Bennu, the ancient Egyptian mythological bird associated with the Sun, creation, and rebirth.

I'd like to wait around to see what happens but last time we sat there watching the clock tick down the apocalypse was a big disappointment, a nonevent so I'm not going to hanging around for this one.

I think you are referring to the end of the Mayan Long Count that occurred on 12 December 2012. The only thing that happened then was the start of a new long count -

2012 Phenomenon

Back then, we didn't have an asteroid bigger than the Empire State Building bearing down on us.

Believe me when I say that I am not a "Doomsday" prepper. But, when Bennu has a close approach to Earth in 2135, it will pass through a "gravity lock" and where it hits that lock, will determine if it hits us (or misses us) on it's next subsequent pass -

Odds of asteroid Bennu slamming into Earth are higher than first thought — but don't panic just yet

"Bennu will have a close encounter with Earth in 2135 when it passes within half the distance of the moon. Earth's gravity could tweak its future path and put it on a collision course with Earth in the 2200s — less likely now based on Osiris-Rex observations.

If Bennu did slam into Earth, it wouldn’t wipe out life, dinosaur-style, but rather create a crater roughly 10 to 20 times the size of the asteroid, said Lindley Johnson, NASA's planetary defense officer. The area of devastation would be much bigger: as much as 100 times the size of the crater.

If an object Bennu’s size hit the Eastern Seaboard, it “would pretty much devastate things up and down the coast," he told reporters."
