Asteroids have struck the Earth more than once in the last billion years. Some of them have changed the course of history. These space rocks are also the reason behind the extinction of dinosaurs. But how can asteroid impact craters, which struck the Earth thousands of years ago be identified? In an astonishing development, a team of international researchers identified the previous impact sites of asteroids using CSI crime solving techniques. But before that, know about this asteroid which is headed directly for Earth, as warned by NASA and it is flying much, much faster than a bullet (around 3000kmph).
The asteroid, named Asteroid 2022 UP17 will fly past Earth today, November 3. This space rock will make its closest approach to the planet at a distance of just 613,000 kilometers from Earth, which is less than twice the Moon's distance from the planet! The 35 feet wide asteroid will pass Earth at the terrifying speed of 69192 kilometers per hour.
According to NASA, the Asteroid 2022 UP17 belongs to the Apollo group of asteroids which are a group of near-Earth asteroids named after the humongous 1862 Apollo asteroid, discovered by German astronomer Karl Reinmuth in the 1930s.
Although this asteroid is not expected to cause any potential damage, it still has been classified as a “Potentially Hazardous Object” due to the close proximity with which it will fly past Earth. NASA's Planetary Defense Coordination Office classifies Near-Earth Objects (NEOs) as potentially hazardous if they come within 8 million kilometers of Earth.
According to the research, only 30 percent of Holocene asteroid impact craters have been identified in the last 11,650 years. The researchers used charcoal samples from crater sites to identify the
