![]() The European Space Agency’s Near-Earth Object Coordination Centre marked it as a 1-in-625 chance and NASA’s Jet Propulsion Laboratory’s Sentry system had it at about 1-in-560. NASA says a newly discovered asteroid has a 'very small chance' of hitting Earth Less than two weeks after it was discovered, asteroid 2023 DW sits at the top of the 'risk list' maintained by the. Though the odds of impact are higher than the average object NASA is tracking, the agency has labeled it’s chances of collision as “extremely unlikely with no cause for public attention or public concern.”Īsteroid 2023 DW, roughly the size of a typical Ferris wheel at your local carnival, was discovered in February, and now NASA says it “has a very small chance of impacting Earth in 2046.” By small chance they mean really small-there’s around a 1-in-600 risk. Solar System Collisions Send an asteroid or comet hurtling toward your favorite planet Target: Projectile Composition: Projectile Diameter: Projectile Velocity: (Kilometers per second) (Results are Approximate) Millions of collisions since the late 1990s. When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or shooting stars are called meteors.NASA cautions that much can be learned about the true orbital nature of a new asteroid within the first few weeks of monitoring, and the odds of impact will be recalculated as we gather more information about the asteroid’s orbit. It’s the most famous cataclysm ever, the meteorite that probably snuffed out the dinosaurs (along with three-quarters of all life on Earth) when it smashed into our planet 65 million years ago. Hitting Earth about 1.8 billion years ago, this is one of the worlds largest meteorite impact sites ever discovered. The soonest the asteroid would potentially impact Earth isnt for more than two decades. ![]() A new asteroid 165 feet in diameter was recently discovered, and it has a roughly 1-in-600 chance of hitting Earth in 2046.
