An asteroid the size of an SUV (sports utility vehicle) has passed 2950km above the earth recently, according to the US National Aeronautics and Space Administration (NASA) on the 18th. NASA recently observed an asteroid passing over the southern Indian Ocean at 04:08 GMT (11:08 Beijing time), named 2020 QG, with a diameter of about 3-6 meters. At that time, it was moving at a speed of nearly 12.3 kilometers per second, far lower than that of communication satellites in geostationary orbit. The asteroid was first observed by the zweiki transient telescope at Caltech Palomar Observatory six hours after it approached earth. NASA’s Jet Propulsion Laboratory (JPL) said in a statement that if the asteroid collided with the earth, it would not cause any harm to the earth. “This asteroid will disintegrate in the atmosphere and may become a fireball or meteor in the air.” < p > < p > Paul chodas, head of NASA’s Center for near earth objects research, said: “it’s cool to see this asteroid at such a close range, so we can see how the earth’s gravity bends its orbit.” According to JPL’s calculations, the asteroid’s orbit was twisted by 45 degrees due to earth’s gravity. According to NASA, asteroids of similar size will pass the earth several times a year at similar distances, but the orbits of these asteroids are difficult to record unless they directly rush to earth and explode in the atmosphere. Agence France Presse pointed out that one of NASA’s missions is to monitor objects 140 meters in diameter and above, because they pose a threat to the earth. At the same time, NASA’s equipment will also track harmless asteroids such as the 2020 QG.
