“Surely, this possibility will soon be ruled out,” he tweeted. Nasa has given Earth the all clear on the chances of an asteroid called Apophis hitting our planet any time in the next century, having worried space scientists for over 15 years. Italian astronomer Piero Sicoli predicted the chance of 2023 DW hitting Earth was 1 in 400 and devised a map predicting where the asteroid could hit. Space experts say a newly found asteroid has a small chance of impacting Earth about 20 years from now. The dashboard displays the next five Earth approaches to within 4.6 million miles (7.5 million kilometers or 19.5 times the distance to the moon) an object larger than about 150 meters that can approach the Earth to within this distance is termed a potentially hazardous object. Nasa’s planetary defense coordination office told CBS News that its risk of colliding with Earth is currently “very small”. But 2023 DW stands apart from the other 1,448 asteroids on the risk list as the only one with a ranking higher than 0. There, more than 50,000 years ago, a meteorite weighing about 270,000 metric tons (300,000 tons) slammed into the Earth with the force of 2.5 million tons of TNT. That means scientists expect, as of today, the asteroid “poses no unusual level of danger” and “the chance of collision is extremely unlikely, with no cause for public attention or public concern,” according to Nasa’s Center for Near Earth Objects.

They have ranked it a one on the Torino scale, a method developed in 1999 that rates space objects’ risk of colliding with Earth. That is equivalent to going from New York to Los Angeles in 1.6 to 5.5 minutes. Scientists have added 2023 DW to the so-called “risk list”, which details objects floating through space that have the potential to affect Earth. Meteoroids enter Earth’s atmosphere at speeds typically of 12-40 km/s relative to the Earth.
