NASA cuts odds of asteroid impact on Valentine’s Day 2046

NASA just shared an update on 2023 DW, the asteroid it believes has a chance to hit Earth on Valentine’s Day 2046 — and it’s great news.

Eyes on asteroids: Our solar system contains millions of asteroids, and while most will never come close to Earth, an impact from one 460 feet wide or larger could flatten a city . As we know from the dinosaurs , a really big asteroid hitting our planet could cause an extinction event.

Asteroid May Collide With Earth With Force Of 12-Megaton Bomb, Wyoming Astronomer Says - Cowboy ...

That's the projected day asteroid 2023 DW, which was discovered Feb. 26, may cross paths with Earth. The object, estimated to be about 164-feet in diameter, has a 1-in-607 chance of crashing into our planet. 

And while the impact of a 50-meter-wide rock might not be considered an ELE (extinction-level event, for those who haven't seen the 1998 movie "Deep Impact"), a collision could still create a disaster zone over 800 square miles.

Watch the Chelyabinsk Meteor Breakup in this Detailed Simulation - Universe Today

The Chelyabinsk impactor was about 20 meters across. It broke up in the atmosphere in an airburst and sent a shower of debris across the landscape. The event awakened people to the dangers of incoming space debris.

These days, there are many observation programs across the planet. For example, NASA operates its Sentry System and ESA sponsors the NEODyS project. They and others track incoming space rock.
