Will asteroid 2023 DW hit Earth on Valentine's Day in 2046? Know what NASA and ESA have said about its possibility
asteroid 2011 UL21 came close to the Earth at the speed of around 58,000 miles per hour and crossed it at a distance of 4.1 million miles without any impact, the question looming large is- what next? The asteroid passed the Earth approximately 17 times farther away than the moon. But this distance is not too much in astronomical science, where distance is measured in light years. European Space Agency has predicted that a 50-metre-wide asteroid, known as 2023 DW, may visit us on February 14, 2046. Discovered on 26 February, it has a one-in-607 chance of affecting Earth. So, what the rendezvous on Valentine’s Day after more than two decades will be like?

Torino scale
Developed in 1999, the Torino scale is a method to rate space objects' risk of colliding with Earth and this asteroid has been ranked as number one on that scale. This means it poses no unusual level of danger and the chance of collision is extremely unlikely, with no cause for public attention or public concern.
But, according to NASA, asteroid 2023, DW stands apart from the other 1,448 asteroids on the risk list as the only one with a ranking higher than 0.
