While the thought of an asteroid hitting the earth may sound concerning, National Aeronautics and Space Administration (NASA) says people shouldn't be worried. The asteroid has an estimated diameter of around 160 feet, which is about the same size as an Olympic swimming pool or the width of a football field. “We've been tracking a new asteroid named 2023 DW that has a very small chance of impacting the earth.Often when new objects are discovered, it takes several weeks' data to reduce the uncertainties and adequately predict their orbits years into the future，”NASA's Planetary Defense Coordination Office (PDCO) said. The asteroid is ranked on the Torino Scale as Level 1 threat.The scale is a tool to categorize potential earth impacts, with zero being no threat and 10 being something that can cause a global disaster.One on the Torino Scale means 2023 DW is in the normal or green zone. “Current calculations show the chance of collision(碰撞) is extremely unlikely with no need for public concern，”NASA says of the green zone.“New telescopic observations will very likely lead to reassignment to Level 0.” Although 2023 DW doesn't pose a great risk to the earth，NASA has been continuing to work to defend our planet from any asteroid that could cause disasters. In September, 2022，NASA crashed its Double Asteroid Redirection Test spacecraft, or DART，into a asteroid to see if it could change the trajectory of the space rock.NASA later confirmed the mission was a success, and is continuing to research how effective the method is, should a massive asteroid be headed our way. 1．What d
