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 ...
2024 YR 4 is an asteroid with an estimated diameter of 40 to 90 metres (130 to 300 ft) that is classified as an Apollo-type (Earth-crossing) near-Earth object.From 27 January to 20 February 2025, it had an impact rating of 3 on the Torino scale, with a maximum estimated probability of 3.1% that it would impact Earth on 22 December 2032.
If the distance between the asteroid and the centre of the Earth is less than Earth radius then a potential impact is predicted. To take account of the uncertainties in the orbit of the asteroid, many future projections are made (simulations) with slightly different parameters within the range of the uncertainty.
The asteroid YR4's chances of impact now surpass the odds that Apophis once had of colliding with Earth when it was first discovered in 2004. Fortunately, the 130 to 300-foot asteroid is much ...
Over the weekend, the asteroid also dropped to a ranking of 0 out of 10 on the Torino Impact Hazard Scale, a tool for categorizing potential collisions of space objects with Earth. The ranking ...
An asteroid gaining notoriety for its potential to collide with Earth in 2032 was estimated Tuesday to ... This image made available by University of Hawaii's asteroid impact alert system shows ...
Due to Earth's escape velocity, the minimum impact velocity is 11 km/s with asteroid impacts averaging around 17 km/s on the Earth. [22] The most probable impact angle is 45 degrees. [22] Impact conditions such as asteroid size and speed, but also density and impact angle determine the kinetic energy released in an impact event.
