An explosion with 150 Hiroshima bombs could make the planet doomsday in 2022. There are many reasons for the end of the world in 2012, but according to NASA, this prediction may happen ten years later, that is, next year.
Is defined by the National Aeronautics and Space Administration (NASA, English abbreviation) as “potential danger” To asteroid 2009 JF1Because it may affect the earth At 8:34 PM on March 6, 2022, According to the NASA report, although it also estimates that the probability of impact is one in 3,800 (0.026%).
The date of the collision was specified after a detailed observation of the asteroid through the NASA Collision Monitoring System, which classifies objects in the vicinity of the planet based on its size, speed, size, and the year it is believed to be impacted.
NASA considers this space rock to be “potentially dangerous”, Qualified as a Near-Earth Object (NEO), This means it is close enough to be considered a threat to the earth.Asteroids are celestial bodies that orbit the sun with a low or considerable eccentricity., And its inclination on the ellipse can be any angle.
NASA explained in a statement: “The orbital paths followed by some asteroids and comets make them closer to the sun than usual, and therefore closer to the earth.” These asteroids have been monitored by satellites. NASA’s Jet Propulsion Laboratory Use an automated system called Sentry. The system managed to measure a large amount of data that allowed us to determine that 2009JF1 is an Apollo asteroid, that is, its orbit around the sun is greater than that of the earth.
According to NASA, “sentinel It is a highly automated collision monitoring system that can continuously scan the latest asteroid catalog to find possible future impacts on the earth Whenever a potential impact is discovered in the next 100 years, we will analyze it and publish the results immediately here, unless we seek independent confirmation in rare cases. Usually, as other observations appear, the object will disappear from the table when possible effects are no longer detected. Therefore, we maintain a list of deleted objects with a deletion date.
Asteroid 2009 JF1 is currently 375,587,595 kilometers away from Earth, Driving to us nearly 18 kilometers per second. It flew over the earth at an astonishing speed of 65293 kilometers per hour. The space agency observed it through sentinels in 2009 and estimated that its diameter was about 13 meters. Its impact on the earth may cause an explosion equivalent to 230 tons of explosives. You must calculate that the Hiroshima bomb only has 15 kilograms of power.
Although the probability of a collision is small, smaller rocks that usually accompany space objects can enter our atmosphere and burn in them when they fall to the ground to form meteors and meteorites. We usually think of them as being in the night sky. Star rain.
Missions to attack or deflect asteroids
The space agency is currently working on missions to attack these asteroids that pose a threat to the Earth and enable them to deviate from their flight paths.
This is the case with the DART spacecraft, which will be launched in mid-2021 for a collision with Dimorphos, which is one of the most dangerous asteroids on Earth due to its characteristics. DART and the European Space Agency (ESA) are part of NASA’s Hera mission.
