The object was small , and likely would have only caused a local effect if it had hit the earth's atmosphere, but it was discovered only 4 days before it passed. The number of 1km asteroids that would make an object as large as Earth is simply the ratio between the volume of the Earth and the volume of a single asteroid: VE V = 1.087 × 1012 km3 0.524 km3 = 2.074 × 1012. [Page 35] at the GodlikeProductions Conspiracy Forum. As you might have expected, larger asteroids deal more damage upon impact, but it's interesting to see how exponentially the damage grows with even the most insignificant of a size difference between two unlike asteroids. How would NASA stop an asteroid? That gives us some hope. If it were only 5 m across, the impact could release about as much energy as the nuclear explosion at Hiroshima. ( Space.com article) In this post, I will use a web-based impact calculator to look at the potential impact of an asteroid like this on the Earth. The researchers conclude that with 6 months' notice, "humanity could in theory defend itself with an array of nuclear penetrators launched 5 months prior to impact.". Fig. Wiki User. (Answer) At this speed, the asteroid would not have to be par-ticularly large to do considerable damage at impact. If a mile-wide asteroid hit Earth, it would strike the planet's surface at about 30,000 mph. A massive Asteroid impact could kill millions. I have promoted this article with Asteroid size danger from regular contributor Goat Guy. Science. How big would an asteroid cause damage? Fortunately, the vast majority do not. If a rocky meteoroid larger than 25 meters but smaller than one kilometer ( a little more than 1/2 mile) were to hit Earth, it would likely cause local damage to the impact area. An asteroid that big traveling at that speed has the energy roughly equal to a 1 million megaton bomb. If a mile-wide asteroid hit Earth, it would strike the planet's surface at about 30,000 miles per hour (48,280 kilometers per hour). In other words, the asteroid will miss us by more than 3.58 million miles (5.77 million km). Explosion Obviously, something this big hitting the Earth is going to hit with a lot .

How much damage would a 1 mile wide asteroid do? Another study estimated that comets 0.3 km (0.19 mi) in diameter impact the planet once in approximately 500 years and those 1.6 km (0.99 mi) in diameter do so just once in every 6,000 years. But even that wouldn't be completely catastrophic. Impacts of asteroids bigger than 1 kilometer are thought to be capable of causing long-term climate damage on a global scale. The damage inflicted by the impact was similar to a nuclear bomb blast, but without ionizing radiation damage. bluefin bay on lake superior . Copy. Suppose a cylindrical asteroid 10 km in height x 10 km in diameter impacted the earth at 30,000 mph. Alarmingly, about 500 million asteroids of this size are This is based on the blastwave model given in Ref. how much damage would a 1 km asteroid do. It's thought that the asteroid's rapid spin drives material toward the equator causing a bulge in the middle. A 1-kilometer object has a mass = 1.31 billion tons. But occasionally, some do. A quarter of the population of the world could be killed if an asteroid as big as 1 km in diameter is struck by a large asteroid, according to scientists. It can also cause extensive damage for up to 1,000 miles away. You should run for it, b. The asteroid is about a quarter mile (400 meters) wide, large enough to cause considerable local or regional damage were it to hit the planet. It's difficult to imagine 1 million megatons, so let's try some smaller sizes. It would take about two trillion asteroids to form an object with the volume of the Earth! Statistically, every 100 million years a 6-mile-wide (10 km-wide . Click to see full answer. Massive waves that would circle the planet in about one day, killing one to two billion people in low-lying areas (even with warning, you can't evacuate large cities in 5-10-15 hours).
