The Comet That Created The Perseids Might Bring An End To Humanity
Forbes ^ | 11 Aug, 2017 | Ethan Siegel

Posted on 08/12/2017 8:21:52 AM PDT by MtnClimber

Every object in our Solar System that takes the plunge from out beyond Neptune to our inner reaches, where the rocky planets lie, will become a comet. As it nears the Sun, its ices melt, creating the tails we associate with them, and also creating a debris path that can create meteor showers if they cross Earth's orbit. For thousands of years, the most consistent, spectacular meteor shower has been the Perseids, created by Comet 109P/Swift-Tuttle.

At its incredibly large size (26 kilometers across) and speed, it contains nearly 30 times the energy of the asteroid strike that wiped out the dinosaurs. Over the next few thousand years, it will come perilously close to Earth. If Jupiter — which it also passes by — gives it just the slightest gravitational kick, it could be flung into the Sun, ejected from the Solar System, or hurtled directly into our world. If this were to happen, and it's a real possibility some 2400 years from now, it would mark the largest mass extinction our world has seen in hundreds of millions of years.

Every August, the Perseid meteor shower delights skywatchers everywhere. While some years it's a disappointment, either being washed out by a bright Moon or delivering a relatively sparse stream of particles for Earth to collide with, other years the show is spectacular. This year, the waning gibbous Moon will wash out about half the meteors, making the best time to view it just after sunset, before the Moon rises.

Nah, it would not help if we were hit by a truly "big one".

Besides Evangeline the Cow likes being out in the sun.

At some point we do need to spread out if we want to survive as a species.

I ‘spread out’ last year from 2 acres to 160 acres. :)

I had to leave behind a perfect bunker and my machine gun turret, but I can always re-build those things out here. ;)

(I’m only half-joking.)

"there is an unknown extent of factors besides gravity acting upon the moving bodies within the solar system. Start with the “keyhole.”"

Your 'keyhole' link starts of with Gravitational

Gee I thought the global nutbags predicted the sun to explode into a supernova before that.

Supernova in a few thousand years? Uhm, no one is suggesting that. Try again.

Climate change, earthquakes, floods, super volcanoes, meteors, asteroids, comets, all in no particular order are the OMG’s of the month that are brought out to fear monger the gullible.

Perhaps, tectonic plate shifts, subduction snap backs, seismic activities, volcanic blow outs AND ISLAMISTS AND NORKS notwithstanding...

Some people just have to take the fun out of everything. Anyway, I’ve got my official solar glasses and a bottle of SPF 4000 so I’m good to go.

I was beginning to panic, but you provided a voice of reason. TY

I bet the dinosaurs really enjoyed the Perseid meteor shower every year until.... SMACK!
A small fragment hit the earth.
The insectoids recall how humans enjoyed the Perseid meteor shower then SMACK!
A small fragment hit the earth.

Just under 40 here.

No machine gun nest.

Officially.
