An asteroid for which there is some possibility of a collision with Earth at a future date and which is above a certain size is classified as a potentially hazardous asteroid (PHA). Specifically, an asteroid is a PHA if its Earth minimum orbital intersection distance (MOID) is <0.05 AU and its absolute magnitude is 22 or brighter. [2]

A large asteroid could pass close enough to Earth within the next decade that there's a chance it could strike the planet, according to NASA. The space rock, named 2024 YR4, is between 130 feet ...
An asteroid nearly the size of a football field now has roughly a 0.004% chance of hitting Earth in about eight years, NASA says — with the space agency saying it "no longer poses a significant ...
Asteroid impact prediction is the prediction of the dates and times of asteroids impacting Earth, along with the locations and severities of the impacts. The process of impact prediction follows three major steps: Discovery of an asteroid and initial assessment of its orbit which is generally based on a short observation arc of less than 2 weeks.
