Topper, I don't think you're entering that information correctly at all. You're entering the weight of the object in the mass. Your test objects have the density of some of the most dense objects in the universe.
Yes
No

Depends on speed and impact location, but in most situations yes. We will have plenty of time to say our goodbyes and have mad sex parties though.
An impact from a meteor the size of Texas would evaporate every drop of water on earth, turn the atmosphere into an inferno as all the oxygen is comsumed and, more than likely, turn the entire crust of the planet into molten rock. The earth would be steralised down to the bedrock and would take millions of years to cool to anythin like the current temperature. The gasses of the atmosphere may well be blasted into space by the shockwave. As most of the gas / water is thought to have arrived on earth in the form of comets, the planet may never recover an atmosphere as cometery activity is much less than it was in the early days of the sola system.
So, no survivors, not even single cell organisims, viruses or bacteria.
As to how often this has happened in the history of the earth? Take a look at the moon, count the craters. There are A LOT. The moon is younger than the eath and has a weaker gravitational pull, therefore it is safe to assume that the earth has been hit more times than the moon, whivh means the earth has been hit by asteroids / comets A SHIT LOT.
No. No. False. Wrong. And No.
In fact, No.
And even then, No.
An asteroid the size of Texas, assuming its only a single KM thick, would have the same KE of 11,287,325,000,000 Hiroshima Bombs.
That's right, 11.2 Trillion.
For perspective, thats ~1600 for each person on the planet.
Now, granted, it would only hit one side of the planet. Lets think about that for a second.
It would be travelling at ~25 km per second. That means it would take ~ 4 seconds once it hits the atmosphere for it to hit the ground.
Now, it would likely land in the ocean, flash boiling at least 20% of the planet's water. That alone would cause a dramatic shift in Earth's environment, which would result in massive chaos.
Fortunately for us, the Asteroids impact would cut through the Earth's crust like a fucking sword through milk. And by fortunate for us, I mean we would die instantly instead of slowly and painfully.
Of course, if we're on the other side of the planet, it's worse.
See, the Asteroid will have destroyed the atmosphere, flash boiled a large portion of the Earth's breathable atmosphere and water, and flung enough ash and dirt into what's left of the atmosphere to block all sunlight for a million years.
Even if some people managed to survive the initial impact, the planet would become so cold we would freeze if we came close to the surface. Plants, Animals, Trees... everything we need to survive would die out. We would die slow, painful, torturous deaths.
TLDR: If it hit, we'd be fucked.
Hell, if one does come, I hope it lands right on top of me... it'll be the best way to die.
I sware to god if I see people say this one more time i'm going to go Al Gore style and widely popularise this issue and inform people.
This just made me remember something my 6th grade science teacher said.
He said he hates all the movies where meteors crash into the earth and people watch their own death, because the meteor is traveling so fast you literally wouldn't be able to see it and the next second you would be dead.
Ohhh 6th grade
I would survive in my anti-Meteorite bunker for decades.
What does that have to do with the population being wiped out? Microorganisms survive absolute zero too.

I actually meant 120x, but whatever. The point is still the same, whether the meteor is a mile wide or 720 miles wide, all life (excluding microrganisms) is no more.
