What Would Happen If Asteroid Hit Earth – The small rocky bodies that orbit the sun are known as Asteroids. Like planets, asteroids orbit the sun and are very small. Let us tell you that there are a large number of asteroids in our solar system and most of them reside in the main asteroid belt which is the region between the orbits of Mars and Jupiter. But have you ever thought what would happen if an asteroid hits the Earth? What do scientists predict about this? Let’s read about this topic.
According to the director of the National Aeronautics and Space Administration (NASA) Jim Bridenstine, the prospect of a deadly asteroid hitting the Earth is a different possibility in our lifetimes. He said this at the 2019 Planetary Defense Summit in Washington. A round table exercise held during the 2019 Planetary Defense Conference in College Park, Maryland. A fictional scenario was prepared by NASA asteroid experts where scientists have identified an asteroid that seems poised to hit Earth in 2027. They also discuss which region will be affected, how it will pose a risk and how to respond. If such a situation could exist in real life, scientists would be ready to deal with it. It is thought that telescopes during the exercise in College Park (USA) found an asteroid between 100 and 300 meters in diameter hurtling towards our Solar System at a speed of 14 kilometers per second, 57 million kilometers from Earth. According to astronomers, there is a one percent chance that a space rock will collide with our planet on April 27, 2027. It is also said that the asteroid Apophis will crash into Earth on April 13, 2029. What will scientists do? Did you know that the countries representing the Sixth Planetary Defense Summit on the University of Maryland Campus in College Park are China, France, Germany, Israel, Italy, Russia and the United States. What are Near-Earth Objects (NEO)? What will happen if an Asteroid hits Earth? Let’s learn more. Any asteroid that falls from the sky will have great energy. For example, according to scientists, in 2028, the asteroid 1997XF11 will come very close to the Earth but will not crash into the earth. If the situation changes and the asteroid can hit the Earth at 30,000 mph. Later, it was said that a sky moving at such a speed would have the energy of a million megaton bomb. Isn’t it amazing! It is understood that if an asteroid with this much power hits the Earth, it would wipe out most of the life on Earth. Let’s take an example to understand better. An asteroid the size of a house crashes into Earth at 30,000 mph. Then it would have had the same amount of energy as the bomb that fell on Hiroshima maybe about 20 kilotons. This type of sky would flatten reinforced concrete buildings half a mile from ground zero and level wooden buildings maybe a mile and a half from ground zero. That is, it can cause great damage to any city. There is no doubt that if an asteroid is as big as a 25-story building, the energy is equivalent to the largest nuclear bomb, 25 to 50 megatons. It would measure a reinforced concrete structure more than five kilometers from ground zero. It would completely destroy the major cities of the United States. To get a better understanding, we can say that if a large asteroid hits New York City directly, the force of the impact could reduce everything from Washington D.C. all the way to Boston and it could cause a lot of damage for maybe 1,000 miles. like Chicago. Even dust and debris thrown into space can block the sun and cause many life forms on this planet to die. If such an asteroid were to land in the ocean, it would cause huge waves of several meters in height that would destroy the coast completely. Do you know when the last asteroid hits Earth? 66 million years ago, the last mass extinction caused the death of the dinosaurs and coincided with a large meteorite impact; this was the Cretaceous-Paleogene extinction event. Therefore, we can say that if an asteroid hits the Earth then it will be a very big loss and it will be a very bad day no matter how big it is. Depending on the size of the planet, it can also end life on that planet. What is a Solar Tsunami? What is an Anti-Satellite Weapon (ASAT)?

If An Asteroid Hits Earth, It Is Predicted That The World’s Citizens Will Flee To Asia
The asteroid hitting our planet is a myth. Several movies and books are based on ideas (“Deep Impact”, “Armageddon”, “Lucifer’s Hammer”) — or try to stop one of them.
But the asteroid that hit the Earth is not just a myth, it is a fact. NASA’s Jet Propulsion Laboratory in California has an “Asteroid Watch” whose entire mission is to find and track asteroids (and comets) that the agency thinks will approach Earth.
There are five asteroids on the Asteroid Watch dashboard for December 2022 alone, including two that are thought to be the size of a commercial airliner. Earlier this year, one asteroid – NASA named asteroid (7482) 1994 PC1 – was 2.5 times the height of the Empire State Building in New York City. It flew past Earth on its closest approach in 200 years on January 18, 2022, at a safe distance of 1.2 million miles (1.93 million kilometers).
Why Nasa Plans To Slam The Dart Spacecraft Into An Asteroid
But not all asteroids throughout history have missed Earth. There are obvious craters on Earth (and the moon) that testify to the long history of large objects crashing into the earth. The most famous asteroid ever was the one that hit Earth 66 million years ago. The mountain-sized asteroid left a crater on the coast of Mexico’s Yucatán Peninsula 93 miles (146 km) wide and 12 miles (19 km) deep. Scientists think it created a massive tsunami and dumped so much water and dust into the atmosphere that it blocked sunlight, lowered global temperatures, and caused the extinction of the dinosaurs.
The chances of hitting an asteroid are very small. NASA has tracked 90 percent of near-Earth asteroids that are at least half a mile (0.8 km) in diameter and believes that none of them have a significant chance of hitting Earth.
There may still be large asteroids out there that NASA doesn’t know about. If an asteroid one kilometer in diameter were to hit Earth, it would hit the planet’s surface at about 30,000 miles per hour (48,280 kilometers per hour). An asteroid that big traveling at that speed has the energy of about 1 million megaton bomb.
It’s hard to imagine 1 million megatons, so let’s try smaller sizes. It says a house-sized asteroid is hitting Earth at 30,000 miles per hour (48,280 kilometers per hour). It would have the same energy as the bomb that fell on Hiroshima – maybe 20 kilotons. A sky like this can flatten a reinforced concrete building up to half a mile from where it crashed, and flatten a wooden building perhaps a mile and a half (0.8 km) from ground zero. In other words, it can cause a lot of damage to any city.
Could We Stop An Asteroid On A Collision Course Toward Earth?
If the asteroid were as big as a 20-story building (200 meters [61 meters] on a side), it would have the same power as the largest nuclear bombs currently being made – about 25 to 50 megatons. An asteroid of this size could flatten a reinforced concrete building 5 miles (8 km) from ground zero. It could literally destroy most major cities in the United States.
For an asteroid to destroy almost everything on Earth, it must be very large. Scientists estimate that an asteroid 7 to 8 miles (11 to 12 kilometers) in diameter will hit Earth. Once it arrives, it will create a large dust cloud that will cover the entire planet, block out the sun, and increase the temperature of the asteroid impact. Billions of people will die, and many living things on this planet will be destroyed. But, scientists believe that some will survive. NASA scientists say it would take an asteroid 60 miles (96 kilometers) in diameter to completely wipe out life on Earth.
Asteroid Didymos (below left) and its moon Dimorphos were seen less than three minutes before NASA’s DART spacecraft made impact. This is the last image that includes a complete view of both asteroids.
The good news is that NASA’s Double Asteroid Diversion Test (DART) spacecraft is being launched into space in November 2021 with the sole purpose of blasting off.
