Hey guys,

Let’s imagine we’re standing on the moon, in a base, looking at earth.

Then an asteroid, a big one, twice the size of the dinosaur one, smashes into the centre of, I dunno, the USA. Bang.

What would it look like? A small explosion? Then a sort of fiery shockwave expanding out? How long would it take before the whole planet was affected? How long before the entire atmosphere was either roaring fire or thick grey smoke? Minutes? Hours? Days?

Would it look like half the planet was volcanic and orange and the other half smoke? Or would it all look like hell?

And how big an asteroid would it take to comfortably render humans extinct?

Then what would it be like, say, a week later?

Can someone describe what this would actually LOOK like from the moon?

Thanks.

Also, could you safely watch it? Or would the flash hurt your eyes?

>a meteor killed all dinosaurus.

Anon...I
It was a 2km meteor hitting a massive sulfur desert in actual bolivia i believe (prob uruguay) anyway.
It made a massive cloud around the earth in less than 24h, letting all plants deprived of sun for 3month, enought to kill all of them, killing herbal eating animals, killing flesh eating predators.
Only ones who survived were fish and small birds who relied on eating seeds and fish. Fish eating planctons. Etc...

There is no way we could die from the same things.

you probably wouldn't even be able to see it desu.

>>10042570
What do you mean we couldn’t die? What if the asteroid was TEN times the size?

[Anonymous No.10043210]

>>10042604
Well what would you see? Just the clouds change? Come off it man, you’d see the explosion. Millions of nuclear warheads. You’d see something.

Earth is not this much bigger then the Moon. So you would not see much. You need a telescope.

[Anonymous No.10045283]

>>10045159
So you’re saying it’d still look blue and green after impact? You’d definitely see a change.

[Anonymous No.10045291]

>>10045159
Or are you suggesting it wouldn’t be dramatic? More a gradual change to the atmosphere?

I’d imagine the end point would be a total covering of clouds?

[Anonymous No.10045305]

>>10045159
well you'd need a telescope to see more detailed changes but given a large enough asteroid you could totally see big changes with one. you can pretty easily spot valleys and hills on the moon from Earth

Are you implying you wouldn’t see the explosion?

>safely watch it
I bet some wastes would travel from the initial Earth impact to the Moon :
No atmosphere on the Moon = no natural shield

I don’t know what you mean? Wastes?

You'd see a bright flash at the point of impact. You might be able to see a wave of ejecta moving outward, but most likely you'd just see smaller flashes as larger bolides ejected by the impact splashed down. Over the next few days and weeks, the Earth would be wrapped in cloud cover.

[Anonymous No.10046397]

>>10045963
This is best answer so far. Clouds easily obscure parts of he surface as is, and the debris from such a large and energetic impactor would very quickly make cloud cover comparable to a hurricane. Would be quite notable from that point on. Would likely be impossible to detect the extent of the impact due to the cloud cover for long after. The impact itself will be very bright, however, could go unnoticed depending on the time of day it hit and how distracted the viewer is

[Anonymous No.10046645]

>>10045963
Yes, this is as I imagined. How long would it take, do you think, before the entire atmosphere was covered in clouds?

Fuck off ayylmaos we're not going to do your homework for you.

[Anonymous No.10046926]

>>10042138
You would not be able to see an impact, because it would happen on the other side of the Earth. Our big moon (and it's sphere of influence) works like a shield, Earth can not be hit from this direction by an large asteroid. Moon gravity would pull it down. As a result you get one ore more new crater on the Moon.

The flash of a 12-mile asteroid impact would be enough energy to not only burn your eyes, but vaporize them, and the rest of you along with it.

What kind of cool af school sets this kind of homework?

This sounds reasonable. But think it through. It could come in at a steep angle.

[Anonymous No.10048031]

>>10047270
Even from the moon? I doubt that. Surely it wouldn’t be brighter or hotter than, say, the sun. And you can look at that (briefly).

[Anonymous No.10048055]

it would look like the chelyabinsk meteor except 70 trillion times larger
