What If Halley's Comet Crashed Into the Moon?

What If Halley's Comet Crashed Into the Moon?

There’s a giant, peanut-shaped object orbiting the Sun, and it’s name is Halley’s comet. Like all comets, it’s a cosmic mashup of frozen ice, gases, and dust. Stretching a vast 15 kilometres by 8 kilometres (9 miles by 5 miles), this space snowball streaks by Earth every 76 years and has been circling for 16,000 years. It hasn’t caused us any trouble yet, but that would change if its elliptical return crosses paths with our Moon, causing a devastating collision visible in broad daylight. Would it affect space exploration? How much damage would it do to the Moon? What would happen on Earth?

    You have a video about a giant ball of ice hitting the moon and melting I think and global flooding but I can’t find it and it’s been bugging me.

  6. कट्टर हिन्दू🚩🚩 on June 30, 2023 at 4:52 pm

    It’s impossible for a 15 km comet to do such damage……. Bring some sense in your videos…….. Moon is much much much bigger than that tiny comet



  7. Corpse 2.0 on June 30, 2023 at 4:52 pm

    Imagine a penut wiping out all human on earth😂

  9. Pupu Pupu on June 30, 2023 at 4:54 pm

    Last pass of the comet was around 200 times further from the earth than moon is.



  10. Mansoor Mannix on June 30, 2023 at 4:55 pm

  19. Goldball Industries on June 30, 2023 at 5:03 pm

    METEORS! TSKE EVASIVE ACTION!

    *Proceeds do run straight into the firing zone*



  20. guy tremblay on June 30, 2023 at 5:03 pm

    The moon has no magma , at least not in a fusion state . The moon has solidified almost after its creation like inside a 200 million years period after its creation . The only Magma you would see after the impact would be the one created by the impact itself



  21. DreTalks on June 30, 2023 at 5:03 pm

    I’m the most recent 🙃



  22. Master of Puppets on June 30, 2023 at 5:04 pm

    What if Halley’s comet hits Mars



  23. Mr. D on June 30, 2023 at 5:05 pm

    *We wouldn’t need to mine the Moon because the materials would come straight to us.*



  24. Acestes on June 30, 2023 at 5:08 pm

    What if the Moon crashed into Halleys comet instead? 🤔



  25. Item on June 30, 2023 at 5:10 pm

    He had a great sacrifice.



  26. crawla7 on June 30, 2023 at 5:10 pm

    I have a question, if halleys comet crashed into the moon does that mean there will be no more halleys comet in the future since it cant come back? Will another one be created?



  27. Chicken Nugget on June 30, 2023 at 5:13 pm

    Dont give them ideas



  28. SilverSkyCloud on June 30, 2023 at 5:13 pm

    how deep would these bunkers need to be? base it on worst case scenario



  29. The Account on June 30, 2023 at 5:14 pm

    Earth: hello Halley

    Halley: sorry gotta run

    Moon: Halley watch out.

    Earth: moon noooo!!!!

    R.I.P Moon

    This is stupid



  42. InDred CoLd on June 30, 2023 at 5:25 pm

    Coming back, from 2122, I warned my good friend Stephen Hawking about this when I attended his beautiful party. We had a great talk, and we discussed the fact that Apaphos would be discovered and it would impact on the Northern peninsula not in 2029, but in the beginning of 2030. A slight miscalculation and a pull from the sun, caused it to slow, and change the trajectory.
    Unfortunately, my good friend, Dr. Hawking passed away before we could do much work on the subject.
    All I can tell you, is it will not be an extinction level event, however the ones that are prepared will survive.
    Unfortunately for myself, I am unable to return to my time, as this was a one-way trip.
    Good luck to everyone, and God bless.



  43. whY.LiE09 on June 30, 2023 at 5:26 pm

    There’s magma on the moon?



  44. XxCloudyxX on June 30, 2023 at 5:27 pm

  45. MasterGZ on June 30, 2023 at 5:29 pm

    What if this planet hit the tereformed Mars?



  46. Yonu on June 30, 2023 at 5:30 pm

    I remember seeing it the last time it was here. I am too old now to see the next one.



  47. Troll Kenobi on June 30, 2023 at 5:31 pm

    When you realize Jupiter only protects planets



  48. liljean on June 30, 2023 at 5:32 pm

  50. Asad Mirza on June 30, 2023 at 5:40 pm

    How about a video on what if our solar system was the only thing in the universe?
