Is it bceause that a fresh crater could more complex than one that’s been weathered over tens of thousands of years?The fragments from the breakup are not significantly dispersed. Smaller but similar nasty possibilities are also projected to result from extensive use of nuclear weapons — nuclear winter and all that? The asteroid periodically crosses Earth’s orbit, and there’s even a 1-in-2,700 chance that it could hit Earth between 2175 and […][…] at Bennu in about a year. The impact does not make a noticeable change in the tilt of Earth’s axis and it does not shift the Earth’s orbit noticeably. The air blast would arrive approximately 2.53 minutes after impact with a maximum wind velocity of 69.9 m/s (156 mph) and a sound intensity of 91 dB (loud enough to cause ear pain). Local effects, however, would be much more noticeable.A Bennu impact would create an initial transient crater with a diameter of 3.85 km (2.39 miles) and a depth of 1.36 km (0.846 miles). There would only be a fine dusting of ejecta with occasional larger fragments. During atmospheric entry, Bennu would begin to break up at an altitude of 71,900 meters (236,000 feet). At this distance the ejecta would arrive approximately 5.57 minutes after the impact.
The asteroid periodically crosses Earth’s orbit, and there’s even a 1-in-2,700 chance that it could hit Earth between 2175 and […][…] at Bennu in about a year. Therefore, learning more about the origins of these rocky bodies could answer one of life's burning questions; where did it come from? The major seismic shaking would arrive approximately 1.67 minutes after impact. For reference, the average interval between impacts of this size somewhere on Earth during the last 4 billion years is once every hundred thousand years.The effect of a Bennu impact on Earth would be insignificant on a planetary scale. The air blast would arrive approximately 25.3 minutes after impact with a wind velocity of only 3.13 m/s (7 miles per hour) and a sound Intensity of 63 dB, which is as loud as heavy traffic.A Bennu impact would be a major natural disaster. Under these conditions, multistory wall-bearing buildings will collapse. The Earth is not strongly disturbed by such an impact and loses negligible mass. This means that it would have an uplifted central peak, a broad flat shallow crater floor, and terraced walls. At 5-km distance the major seismic shaking would arrive approximately one second after impact. The tsunami wave amplitude is between 28.2 meters (92.4 feet) and 56.3 meters (185 feet).Life gets a little better for those who witness the impact from a range of 500 km (310 miles) away. Cars and trucks will be knocked over and grossly distorted. Didn’t realise there was enough atmopshere at 2 x GSO to break up an asteroid!I have a few follow-up questions which I’m hoping you will answer. The major seismic shaking would arrive approximately 10 seconds after impact. The volume of the target rock that is melted or vaporized is 0.0382 km3 (0.00916 miles3). calculator lets you investigate the effects of asteroid impacts on Earth for a wide range of conditions.During atmospheric entry, Bennu would begin to break up at an altitude of 71,900 meters (236,000 feet). The broken projectile fragments strike the ground in an ellipse of dimension 1.45 km by 1.02 km, within the formed impact crater.The resulting earthquake is much weaker than the mag 9 you mentioned. The asteroid periodically crosses Earth’s orbit, and there’s even a 1-in-2,700 chance that it could hit Earth between 2175 and […][…] at Bennu in about a year. It orbits around the Sun every 436.6 days and comes within a close distance of 0.002 AU from Earth every six years.The asteroid was discovered in September 1999 and is currently the target of Meanwhile, asteroid Ryugu was discovered in May 1999, measuring around 900 meters in diameter. Asteroid Bennu is a near-Earth Object with a diameter of approximately 500 meters (which is about 3/10 of a mile). Unless you are unfortunately within 100 km or so of the impact site.That is funny. A new study explains their odd spinning-top shapes.Approximately 600 million kilometers from Earth, fragments of rock are scattered in an orbit around the Sun, roughly between the orbits of Jupiter and Mars. The impact would release energy equivalent to 1,450 megatons of TNT. The asteroid periodically crosses Earth’s orbit, and there’s even a 1-in-2,700 chance that it could hit Earth between 2175 and […][…] at Bennu in about a year. * Why would it create a more complex crater than the Meteor Crater? The air blast would cause wood frame buildings to almost completely collapse, glass windows to shatter, and up to 90 percent of trees to be blown down with the remainder stripped of branches and leaves.If Bennu impacted into the ocean, a tsunami would be generated. For comparison, the fission bombs used in World War II had an energy release of roughly 20 kilotons of …
