What would be the effects if a texas size asteroid hit earth at 134,000 MPH.?

Question

How big and hot would the asteroid impact explosion be.

Answer 1

Slightly larger than humongous.

Answer 2

Perhaps none of you know this but there are NO asteroids the size of Texas! And as earth orbits the sun at 65,000 miles an hour it is difficult to see why a co-orbital body would be twice that speed.

TEXAS

Width 773 miles (1,244 km)
Length 790 miles (1,270 km)

BIGGEST FIVE ASTEROIDS

Name, Size in Kilometres. Distance from Sun in AU

1 Ceres 975×909 2.766
4 Vesta 578×560×458 2.361
2 Pallas 570×525×500 2.773
10 Hygiea 500×385×350 3.137
511 Davida 326 3.170

All out beyond Mars, So how is this fantasy scenario to be played out?

Where is this supersized asteroid going to appear from? How is it going to cross inside Mars' orbit? And how is it going to be speeding along at twice the going rate in a built-up area?

I think this sort of question just worries people needlessly. This is simply not going to happen!

Stand back!

I plugged in a much smaller one and was standing 100 miles away... I got incinerated!
--------------
Energy:
Energy before atmospheric entry: 3.92 x 1029 Joules = 9.37 x 1013 MegaTons 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 Earth's rotation period or the tilt of its axis.
The impact does not shift the Earth's orbit noticeably.

Crater Dimensions:
What does this mean?


Transient Crater Diameter: 2860 km = 1770 miles
Transient Crater Depth: 1010 km = 627 miles

Final Crater Diameter: 8080 km = 5020 miles
Final Crater Depth: 4.44 km = 2.76 miles

The crater formed is a complex crater.
The volume of the target melted or vaporized is 3.02e+09 km3 = 7.25e+08 miles3
Roughly half the melt remains in the crater , where its average thickness is 472 km = 293 miles

Answer 4

Well besides destroying all life on the planet not sure what to say. The ash would blanket our skies blocking sunlight killing plant life, thus killing off everything since plants are the basis of the energy cycle. The ash would also cause the oceans to become more acidic killing off reefs which are the basis of life in the oceans. So it would be the end of our planet. Bacteria would be about the only thing to survive they always do. The asteroid that killed off the dinosaurs that hit the Earth at the Yucatan peninsula was only a tiny fraction in size in comparison.

Also the asteroid would be traveling a lot faster than 134,00mph.

Answer 5

Asteroid the size of Texas, could be an Earth killer. plenty larger than the asteroid that killed the dinosaurs. it stands out as the tip of existence on the earth, yet in step with threat a clean commencing up.

Answer 6

A large shock wave would circle the world. Most likely almost everything withing a large radius of the hit would be vaporized. The dust would get thrown into the atmosphere causing global cooling and eventually a mass extinction of both plant and animal life forms.

Answer 7

Can you pronounce the word C-A-T-A-S-T-R-O-P-H-E? If such an event occurred, earth would probably be pushed drastically out of its current orbit around the sun and life as we know it would probably come to a crashing halt.

Answer 8

All life as we know it would cease instantaneously & every molecule in your body explode at the speed of light, so yeah a 10+ on the quivering scphincter scale...

Answer 9

We would all die. If not from the impact, from the resulting catostraphic effect on the atmosphere.

Answer 10

Think water melon being shot with a 50 cal.
