An asteroid like three soccer fields is coming tomorrow to Earth

ABC Science


A asteroid about 330 meters in diameter, three times as long as a football field, will approach the neighborhood of Earth tomorrow at a devilish speed of 40,800 km per hour. The rock, called 2008 KV2, will approach the more than prudent distance of 6.7 million kilometers (17 times that separates us from the Moon) so, although it is considered as potentially dangerous, does not pose any threat to the Earth and the opportunity for scientists to learn more about these space bodies.

According to LiveScience, astronomers at NASA's Center for Near-Earth Object Studies (CNEOS) discovered the asteroid in 2008, but it was not the first time it visited us. In fact, it has come frequently in the past and will continue to do so in the future. The last time it flew over the Earth was less than a year ago, on December 11, 2018, approaching a distance of 0.47 astronomical units or about 70 million kilometers. Now it will do it at 0.04548 astronomical units. The next time the asteroid visits Earth's surroundings it will be in 2021 and it will repeat twice in 2022, according to NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California.

Potentially dangerous

2008 KV2 is what NASA considers a Object near Earth (NEO by Near Earth Object), since it flies less than 50 million kilometers from us. Due to its trajectory and its size, it is also classified as potentially dangerous. Of course, absolutely nothing will happen tomorrow, but the asteroids can change their "flight plan" by the gravitational attraction exerted by the nearby planets. In the case of KV2, it is modified each time it passes close to Earth and Venus, which in turn modifies each year the distance that separates it from these planets. That is why, although today it seems safe, astronomers have to continue watching this great rock.

Due to its massive size, Similar to what is believed to be the famous asteroid Apophis, an impact on Earth would have devastating consequences, since it would amount to the explosion of 20,000 atomic bombs. Several hundred kilometers around the impact zone would be devastated and could have repercussions on the climate, altering the way of life.
