The details of the exercise that NASA played out, along with FEMA (Federal Emergency Management Agency) and the Department of State Office of Space Affairs, was that an imagined asteroid was spotted that had a 72% chance of hitting Earth in around 14 years’ time. With a long lead time, ...
“Again, there is no existing evidence that an asteroid or any other celestial object is on a trajectory that will impact Earth,” said Chodas. “In fact, not a single one of the known objects has any credible chance of hitting our planet over the next century.”...
Neither Dimorphos or Didymos are currently a threat to Earth. According to NASA, there is no known asteroid larger than 140 meters (459 feet) with a"significant chance"of hitting Earth in the next century. However, only about 40% of those asteroids have been found as of October 2021. Ill...
“The NEOWISE mission has been instrumental in our quest to map the skies and understand the near-Earth environment. Its huge number of discoveries have expanded our knowledge of asteroids and comets, while also boosting our nation’s planetary defense,” said Laurie Leshin, director of NASA’s ...
When an asteroid plows into the Earth, it destroys pretty much everything in its path. But new research has shown that glass created during a searing asteroid impact can actually trap microscopic signs of life for millions of years, providing scientists
Right now, NASA’s Near Earth-Object Program says there are no big asteroids at risk of of hitting Earth anytime soon. That doesn’t mean we’re totally in the clear. Tiny space rocks, like the ones produced by a 2013 meteor blast overChelyabinsk, Russia, that injured more than 1,000...
during that passage its probability of hitting Earth is thought to be near zero. The collision of a sufficiently large NEA with Earth is generally recognized to pose a great potential danger to human beings and possibly to all life on the planet. For a detailed discussion of this topic,see...
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 2046, according to NASA’s Planetary Defense Coordination Office.

The NASA Double Asteroid Redirection Test (DART) Mission aims to change the trajectory of an asteroid 11 million kilometres from Earth by hitting it with a craft the size of two cars end-to-end. The craft will be moving at an astronomical 6.6 kilometres per second. ...
