>What would happen if Ceres hit the Earth?
We'd be invaded by the same aliens that pushed it out of its orbit.

>>7520745

That's a big rock.

>>7520745
>Ceres

We'd be proper fucked.

>>7520745
Woul be the biggest Extinction-event ever. Would prolly end live on earth forever tbh.

>>7520778
UUUU

>>7520745
The moon would probably intercept it and fling it away. But it depends on the speed Ceres is moving. Then again so does your question

>>7520745
It would cause a ceresly big crater.

All life on earth would die, the atmostphere would disappear, all water would vaporise, the planet would break apart into several pieces.

nice try, but no

Stop laughing. I'm ceres. :P :D

>>7520857
Accurate up until the break up into several pieces part.

It depends on the velocity. anything from just gently landing on earth and screwing with our days cause it would cast a huge shadow to hitting us at close to the speed of light and blasting everything on both into quantum particles.

why

>>7520947
same content
less bullshit

Basically here's what would happen.

An advanced alien species would teleport and use their technology to remove the object and save us. We are simply too important to go extinct.

It would probably turn the Earth into something like Venus. After a couple million years of molten lava covering the surface.

>>7520947
Apologies

>>7520745
It would smack the planet and kill everything.

What the hell did you think would happen?

This would happen.

the amount of force from the collision would cause a black hole to form and cause a metastability event that would destroy the universe instantly

We would all die

Well let's see, OP

Inputs:

Distance from Impact:20000.00 km ( = 12400.00 miles )
Projectile diameter:950.00 km ( = 590.00 miles )
Projectile Density:2245 kg/m3
Impact Velocity:20.00 km per second ( = 12.40 miles per second )
Impact Angle:45 degrees
Target Density:1000 kg/m3
Target Type: Liquid water of depth3.7 km ( = 2.3 miles ), over crystalline rock.
(Lands in the ocean)

Energy:

Energy before atmospheric entry:2.02 x 1029
Joules=4.82 x 1013MegaTons 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.

Major Global Changes:

The Earth is not strongly disturbed by the impact and loses negligible mass.
The impact does not make a noticeable change in the tilt of Earth's axis (< 5 hundreths of a degree).
Depending on the direction and location of impact, the collision may cause a change in the length of the day of up to18.6 minutes.
The impact does not shift the Earth's orbit noticeably.

Crater Dimensions:

The crater opened in the water has a diameter of3460 km ( = 2150 miles ).
For the crater formed in the seafloor:
Transient CraterDiameter:2110 km ( = 1310 miles )
Transient Crater Depth:746 km ( = 464 miles )
Final CraterDiameter:5740 km ( = 3570 miles )
Final Crater Depth:4.01 km ( = 2.49 miles )
The final crater is replaced by a large, circular melt province. The volume of the target melted or vaporized is 1.26e+09 km3= 3.02e+08 miles3
Melt volume =1.02times the crater volume
At this size, the crater forms in its own melt pool.

Thermal Radiation:

The fireball is below the horizon. There is no direct thermal radiation.

Part 1 of 2

Seismic Effects:

The major seismic shaking will arrive approximately1.11 hoursafter impact.
Richter Scale Magnitude:13.8(This is greater than any earthquake in recorded history)
Mercalli Scale Intensity at a distance of 20000 km:

VII. Damage negligible in buildings of good design and construction; slight to moderate in well-built ordinary structures; considerable damage in poorly built or badly designed structures; some chimneys broken.

VIII. Damage slight in specially designed structures; considerable damage in ordinary substantial buildings with partial collapse. Damage great in poorly built structures. Fall of chimneys, factory stacks, columns, monuments, walls. Heavy furniture overturned.

Ejecta:

Little rocky ejecta reaches this site; fallout is dominated by condensed vapor from the projectile.

Air Blast:

The air blast will arrive approximately16.8 hoursafter impact.
Peak Overpressure:2.68e+06 Pa = 26.8 bars = 380 psi
Max wind velocity:1290 m/s = 2880 mph
Sound Intensity:129 dB(Dangerously Loud)
Damage Description:

Multistory wall-bearing buildings will collapse.

Wood frame buildings will almost completely collapse.

Multistory steel-framed office-type buildings will suffer extreme frame distortion, incipient collapse.

Highway truss bridges will collapse.

Highway girder bridges will collapse.

Glass windows will shatter.

Cars and trucks will be largely displaced and grossly distorted and will require rebuilding before use.

Up to 90 percent of trees blown down; remainder stripped of branches and leaves.

Tsunami Wave:
The impact-generated tsunami wave arrives approximately29.2 hoursafter impact.

Tsunami wave amplitude is between:319.0 meters( =1050.0 feet) and638.0 meters( =2090.0 feet).

You forgot to mention Complete and utter extinction of every organism that's bigger than a few inches.

Correct. We'd have evacuated long before.

That's no moon.

>that "photo" of the earth

>>7520817
cleaver

>>7525424
"Moon" is so damn boring, why don't they just call it Luna?

>>7525440
it saddens me that mars is so small compared to earth and venus who is almost the size of earth is closer to the sun

>>7526108
but it is called luna, in spain.

If Ceres hit Earth everything would die and mass surface destruction would occur.

>>7525440
Why are the images for Europa and Triton so wrong? We've had decent quality images of them for 25 years. Longer than the Magellan data on which Venus seems to be based instead of an actual photo of the atmosphere.
