Is it true I have more chance of expiring from a global cotastrophe in the next 50 years as a result of a terestrial object from outer space colliding with Earth than winning the powerball with a $1 ticket.
Both land and ocean impacts raise enough dust to affect climate, freeze crops. Ocean impacts generate global scale tsunamis. Global destruction of ozone. Land impacts destroy area the size of a large state (California, France, Japan). A 30-km creater penetrates through all but the deepest ocean depths.
If a massive near-Earth object measuring more than a kilometer (0.6 mile) in diameter slammed into the planet it would cause global devastation and kill an estimated quarter of the world's population. But scientists believe an event of that size would only occur about every 700,000 years
Asteroids capable of inflicting damage on a global scale hit the Earth roughly every million years...
Roughly speaking it seems that once every 100,000 years an object hits the Earth of sufficient size to wipe out a quarter of life on Earth
selfAdjoint said:At that rate the Earth would be covered with big craters, erosion and mountain building wouldn't have had time to diguise them.
selfAdjoint said:Well that's 5 KT level events in the last 3 million years (give or take 1 for distribution).
bozo the clown said:ok there is no question that we do face risk from a major impact whether it be from small area destruction to widespread global destruction. The question is do we have the facilities to gauge fair notice as to whether an object is going to collide with the Earth and can we ultimately prevent it from striking our planet.
bozo the clown said:oh dear its as bad as that huh
ok let's say an asteroid with say a diameter of 2km hit 'say for sakes of arguments' a sparse area in Arizona what effect would it have ?

Your Inputs:
Distance from Impact: 500.00 km = 310.50 miles
Projectile Diameter: 2000.00 m = 6560.00 ft = 1.24 miles
Projectile Density: 8000 kg/m3
Impact Velocity: 10.00 km/s = 6.21 miles/s
Impact Angle: 45 degrees
Target Density: 2500 kg/m3
Target Type: Sedimentary Rock
Energy:
1.68 x 1021 Joules = 4.00 x 10^5 MegaTons TNT
The average interval between impacts of this size somewhere on Earth during the last 4 billion years is 2.3 x 10^6 years
Crater Dimensions:
Final Crater Diameter: 29.61 km = 18.39 miles
The odds of Earth being hit by an asteroid are significantly lower than winning the Powerball jackpot. According to NASA, the odds of Earth being impacted by an asteroid with a diameter of 1 kilometer or more in the next 100 years are about 1 in 300,000. On the other hand, the odds of winning the Powerball jackpot are about 1 in 292 million.
Winning the Powerball jackpot is more likely to occur than an asteroid impact on Earth. The odds of winning the Powerball jackpot are about 1 in 292 million, while the odds of Earth being hit by an asteroid with a diameter of 1 kilometer or more in the next 100 years are about 1 in 300,000.
Scientists calculate the odds of Earth being hit by an asteroid by tracking and monitoring asteroids in our solar system. They use data such as size, trajectory, and frequency of close approaches to make predictions about potential impacts. The more information they have about an asteroid, the more accurate their calculations will be.
Yes, the odds of Earth being hit by an asteroid can change over time. As scientists continue to gather more data and track asteroids in our solar system, they may discover new asteroids that could potentially impact Earth. This can alter the odds and increase or decrease the likelihood of an impact in the future.
There are various methods that scientists and researchers are exploring to prevent asteroid impacts on Earth. These include deflecting the asteroid's trajectory using a spacecraft, detonating a nuclear device near the asteroid, or using gravitational attraction to alter its path. However, these methods are still in the research and development stage, and it is currently not possible to prevent an asteroid impact with certainty.
