What would happen if a 1 kilometer wide asteroid hit the Earth? Although the early original criticism had not undergone peer review, a more recent peer-reviewed study was subsequently published. Although speculative, the author, Michael Paine suggests the effects of asteroid diameters of 1 km, 2 km, 5 km, and 10 km. At that scale, it would release energy equal to about 100,000 megatons of TNT. One kilometer is a little over half a mile wide (0.621 miles). We should also consider that the “wiseguy” will return 14 years after this. An asteroid measuring between 1.8 km and 4.1 km in diameter will “closely approach” Earth on 29 April, the CNEOS’s tracking list revealed.The near-Earth object (NEO) is officially called 52768 (1998 OR2) and previously came close to Earth on 12 March 2009.. In May 2016, significant asteroid data arising from the Wide-field Infrared Survey Explorer and NEOWISE missions have been questioned. We should also consider that the “wiseguy” will return 14 … The famous UK landmark is 443 feet high. A huge and "potentially hazardous" asteroid believed to be more than one and half times the size of the London Eye is approaching Earth. In other words, the asteroid will miss us by more than 3.58 million miles (5.77 million km). Forget weather- the damage created would potentially wipe out half of the life on Earth. Asteroid OR2 will drastically cut this down to just 3.9 million miles (6.29 million km) on April 29. Asteroid Florence, a large near-Earth asteroid, will pass safely by Earth on Sept. 1, 2017, at a distance of about 4.4 million miles.

In the wake of already existing Covid-19 Coronavirus, an asteroid big enough to end human civilizations is expected to pass close by Earth in April. 2010-03-28 20:30:49 2010-03-28 20:30:49. We believe anything larger than one to two kilometers – one kilometer is a little more than one-half mile – could have worldwide effects, Thankfully, the 2002 PZ39 asteroid will miss our planet by around the distance of 3.58 million miles (5.77 million km). Measuring between 1,443ft and 3,248ft (440m to 990m) in diameter, the giant space rock, which is officially known as 2002 PZ39, dwarfs the Burj Khalifa, Empire State Building, the Shard in London, and even the oft-discussed, pseudo-apocalyptic Bennu asteroid.

The asteroid is expected to pass by […] Once the asteroid shoots by, NASA predicts it will pay a visit to the planet Venus on June 14, 2034. CharlVera / Pixabay.

What would happen if a 1 kilometer wide asteroid hit the Earth? The initial blast would also produce shifting of the crust along fault lines.

Recent evidence proves that the asteroid that is approaching the earth is half as wide as Mount Everest tall and will reach near to the Earth by next month. Massive 1.4-kilometer-wide asteroid set for a close shave with Earth on April 19th Object 2014 JO25 is estimated be between 640 meters and 1.4 kilometers wide …
NASA has identified a huge asteroid that is 2.5 miles, or 4.1 km across. We believe anything larger than one to two kilometers – one kilometer is a little more than one-half mile – could have worldwide effects, Thankfully, the 2002 PZ39 asteroid will miss our planet by around the distance of 3.58 million miles (5.77 million km). Top Answer. Indeed, at its closest approach, the roughly 1.5-mile-wide (2.4 km) 1998 OR2 will still be about 16 times farther from us than the moon is from the Earth. Researchers have officially given the asteroid the name of “52768 (1998 OR2)” and say that it is traveling at an estimated speed of 8.7 km per second, which is about 31,320kmh or 19,461 mph. A monster asteroid with a diameter of 1.8 – 4.1 km is set to fly past Earth on April 29. 2010-03-28 20:30:49 2010-03-28 20:30:49. Known as 1998 OR2, the asteroid is classified as a "potentially hazardous object" as it is bigger than 140 metres and passes within 8 million kilometres of Earth's orbit.
Quite a lot of damage, but not an extinction-level event if that’s what you were worried about. An asteroid measuring four kilometres wide and big enough to potentially end human civilisation is expected to pass close the Earth in April. Depending on where it hits, it might be anywhere from very damaging to catastrophic. Wiki User. Environmental Damage from Asteroid and Comet Impacts. Plugging in the typical impact values, you get a 150-kilometer diameter crater for the 10-kilometer asteroid and a 20-kilometer diameter crater for the 1-kilometer asteroid. A two-kilometre-wide "potentially hazardous" asteroid is set to pass by Earth on Wednesday, NASA said, adding that the space rock will pose no danger to our home planet in this fly by. An asteroid more than a mile wide will pass by Earth on Wednesday while travelling at a speed of about 19,000 miles (30,578km) an hour.
