For best viewing, let the video play once, then play it to avoid the video stopping every 20 seconds..

| So...........That would be bad right? I mean that is the worst that could happen? I just want to know how bad it could get. |

I think some humans will still live though..
I mean there are some mines which are like 3 km deep...
wouldnt a human be able to survive there?
or also the seed bank vault in the arctic wouldnt that be a place to survive? of course only if the impact site was not around there |

| Nobody on Earth can survive that. Being in a deep mine would just mean that you get an instant coffin. The earthquakes would bury you. |

Video didn't play for me. It kept stopping...And I closed it. It probably wasn't meant for me to see the end of the world.
Proinvestor? Why in the world is a finance site showing a video about us getting our world rocked by a big rock? |

yeah, really, why would anyone want to invest anything after seeing that? Especially that part at the very end, "evidence shows this has happened at least 6x before in earth's history". Geez, why put any money into anything when its imminent that its all going to get vaporized anyway?
Incidentally, while they do believe that the earth has been hit by asteroids several times in its geohistory, I dont think any scientists out there think the asteroid was 500km... I recall they believe the one that wiped out the jurassic dinosaurs was more like 10km... And the one that Bruce willis and Ben Affleck drilled a hole into and nuked a few years ago was only 50km... |

That was the sub-prime mortgage rock. |

The video closes with the ominous statement that scientists believe that the Earth has been hit by similar asteroids 6 times before......maybe true.......
...........but the reason for that is that the solar system used to be a much busier place with countless asteroids flying around. For the last couple of billion years, Jupiters huge gravitational pull has taken care of most of the asteroids in the solar system. Planet destroying asteroids are very rare now..........
.........but still out there! |

500km, iron, 17km/s, 6000km from impact.

Energy:
Energy before atmospheric entry: 7.57 x 1028 Joules = 1.81 x 1013 MegaTons TNT
The average interval between impacts of this size is longer than the Earth's age.
Such impacts could only occur during the accumulation of the Earth, between 4.5 and 4 billion years ago.
The crater opened in the water has a diameter of 2980 km = 1850 miles
Your position is inside the fireball.
The fireball appears 221 times larger than the sun
Thermal Exposure: 6.14 x 1011 Joules/m2
Duration of Irradiation: 110000 seconds
Radiant flux (relative to the sun): 5580
The major seismic shaking will arrive at approximately 1200 seconds.
Richter Scale Magnitude: 13.5 (This is greater than any earthquake in recorded history)
The ejecta will arrive approximately 1890 seconds after the impact.
Your position is beneath the continuous ejecta deposit.
Average Ejecta Thickness: 454 m = 1490 ft
The air blast will arrive at approximately 18200 seconds.
Peak Overpressure: 1.96e+07 Pa = 196 bars = 2790 psi
Max wind velocity: 3560 m/s = 7960 mph
Sound Intensity: 146 dB (Dangerously Loud)

No object in the solar systemis both this large and on a possible collision orbit.
The impacts in the past were roughly 20,000 times smaller. As bad as it gets would be about 10km or so across. Still bad; we're talking km high tsunamis here. Or if it hits land it'll take out a contentient, and the rest of the world would have a ten year winter.
There are plenty of other things that could do us in though. Rouge black holes, nearby supernovae or gamma ray bursts, aliens, gray goo, nuclear wars, environmental devestation etc etc... |
