How Scientists Identify Apocalyptic Asteroids Heading For Earth | Naked Science | Spark

Earth is at constant risk from asteroids and other space debris. The vast majority of these impacts are minimal and have almost no effect on the planet. However over the course of its life, earth has been hit with asteroids that caused such major damage that it changed the planet for centuries to come. How do we know when the next major impact could be? Is there anything we can do to stop it?

Well if an asteroids is headed towards us from the direction of the sun, there's not much we can do because it's impossible to see.

Good thing it’s only a thousand billion tons and not a trillion tons!

It's going to happen so quickly in a split second we all won't feel nothing just won't be on thus earth anymore

this doc is missing one guy, , , Randall Carlson...

This is a good documentary but, like all docs of this type they quickly become dated. The DART mission changed things quite drastically, for the better.

NASA has a great idea to save the planet earth 🌍🌏

[johnhopkins]

While comparisons with nuclear weapons is impressive, a detail of the type(s) of energy released by penetrating asteroids may be more informative. (i.e. heat, light, mechanical, etc.)

Fine example of how small, starts look ruin is very local, somewhere far away. 1917 air two yrs zone glimpses. John.

@ 33:10 no, send up a probe towards the sun and as the meteor passes the earth, rendezvous with the asteroid then explode a nuke in a position that gets it to fragment the sun

[classesanytime]

No worries folks!!
If humanity stays on this course, it will have destroyed itself long before any astroid will have the honor to do so!!
Humanity will be victorious!!
Humanity 1 - 0 Astroid

Dr. Massimiliano Vasile…that is a straight up rock star name!!

Were the dinosaurs the only living animals, ? Or how did the other animals survived?

[mrrob]

If we hit a solid asteroid with a nuke how would it do more damage? Wouldn’t it break it into so many smaller pieces that would eventually burn up in our atmosphere? I know it wouldn’t magically go away but I would think it would help to some degree.

[arnoldalar]

Just wondering, why most asteroids hit unpopulated places?

T AM SORRY I DO NOT REMEMBER M0ST OF WHAT YOURE SAYING BUT I CAN ONLY REMEMBER FRAGMENTS OF THE TIMES YOU MENTION I AM THREE HUNDRED AND EIGHTY FIVE THOUSAND YEARS OLD. I AM THE FIRST BORN ONLY BITS COME BACK TO ME...ONLY FRAGMENTS SEAM TO AWAKEN WITHIN ME. THERE WAS SO MUCH BUILDING GOING ON AT MOST TIMES..OF COURSE ONLY SMALL BITS COME BACK TO ME. AT A TIME. I REMEMBER MOST PRESIDENTS, I REMEMBER THE MEXICO COMMIC CRASHING.I LIVED MOSTLY IN THE JUNGLE FOR MANY THOUSAND YEARS OF COURSE ONLY SMALL PORTIONS OF THE PAST ARE BROUGHT BACK TO ME, I GUESS IT TKES TIME. THERE ARE MANY THINGS I COULD TELL YOU IN FACT MANY ANIMALS COULD SPEAK ENGLISH. THE MOST AMAZING THING WAS WHEN THEY DISCOVERED FIRE, MANY PEOPLE GOT BURN TRYING TO PLAY IN THE FIRE. THOSE WERE TRULY WONDERFUL TIMES. I KNEW ABOUT FIRE SINCE I WAS FROM A DIFFERENT PLANET. UNTIL THE REPTILIANS BLEW UP MY SHIP AND GOD MY FATHER PUT ME BACK TOGETHER AGAIN THIS WAS VERY LONG TIME AGO., THE THINGS YOU MENTIONWAS BEFORE MY TIME. BUT I REMEMBER MUCH.

I found Dr Ken Tankersley to be quite cantankerous while discussing Carancas.

[renstimpy]

i dont think it was one rock that hit us....i think it more like buckshot when we passed through the torrid meteor shower...
