8/26/2023 0 Comments Nasa asteroid watch list![]() The last full moon was two days ago, and it still appears bright and large in the sky, likely obscuring 2023 DW from immediate observation, he said. It may be a few days before new data can be collected because of the asteroid's proximity to the moon, Farnocchia noted in an email to CNN. "Most often, the threat associated with a specific object will decrease as additional observations become available." "However, such early predictions can often be ruled out as we incorporate more observations and reduce the uncertainties in the object's orbit," it reads. Though the 2023 DW tops the list, its ranking of 1 means only that "the chance of collision is extremely unlikely with no cause for public attention or public concern," according to the Jet Propulsion Laboratory, while a 0 ranking means the "likelihood of a collision is zero, or is so low as to be effectively zero."

The latter tracks potential collisions with celestial objects.īut the space rock - named 2023 DW - is the only object on NASA's risk list that ranks 1 out of 10 on the Torino Impact Hazard Scale, a metric for categorizing the projected risk of an object colliding with Earth. The asteroid has a 1 in 625 chance of striking Earth, based on data projections from the European Space Agency, though NASA's Jet Propulsion Laboratory's Sentry system calculated the odds closer to 1 in 560. The DART mission, or the Double Asteroid Redirection Test, launched 10 months ago.ĬHICAGO - A newly discovered asteroid roughly the size of an Olympic swimming pool has a "small chance" of colliding with Earth in 23 years, with a potential impact on Valentine's Day in 2046, according to NASA's Planetary Defense Coordination Office. ET greeted by cheers from the mission team in Laurel, Maryland.
