Asteroid headed toward Earth may arrive on Valentine's Day 2046
Asteroid 2023 DW has a better chance of hitting a date of 14 February than our planet, NASA says.A newly detected asteroid has a very small chance of impacting the Earth in 2046, NASA tweeted on Tuesday.Valentine's Day 2046The closest the asteroid is expected to get to Earth is about 1.1 million miles , NASA says.The asteroid, dubbed 2023 DW, has about a 1 in 560 chance of hitting Earth, according to NASA.
The scale, which goes from 0-10, measures the risk of space objects colliding with Earth. All other objects on the scale rank 0, indicating no risk for impact. A ranking of 1 means that an actual collision is extremely unlikely and no cause for public concern, NASA's Jet Propulsion Laboratory says.If it does collide with us, 2023 DW would not have the same doomsday effect as the asteroid that decimated the Earth's dinosaurs 66 million years ago. That asteroid was far bigger at 7.5 miles wide,But an impact from 2023 DW could still cause significant damage if it were to land atop a major city or densely populated area.
While contact with an asteroid seems unlikely, scientists have been preparing for such an encounter for years. Last October, NASA confirmed the agency's Double Asteroid Redirection Test mission had successfully changed the travel path of a small asteroid by slamming a spacecraft into it. "That's the very reason why we flew that mission," Mr Farnocchia said, "and that mission was a spectacular success."
