(308635) 2005 YU 55, provisionally named 2005 YU 55, is a potentially hazardous asteroid [2] 360 ± 40 meters in diameter, as measured after its Earth flyby. [8] Previously it was estimated to be 310 meters [5] or about 400 m (1,300 feet) in diameter.

The minimum orbit intersection distance (MOID) between an asteroid and the Earth is the distance between the closest points of their orbits. This first check is a coarse measure that does not allow an impact prediction to be made, but is based solely on the orbit parameters and gives an initial measure of how close to Earth the asteroid could ...
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 ...
The only time an asteroid of similar or larger size has been classified higher on the Torino scale was in 2004, when the asteroid Apophis was briefly ranked as a Level 4, with an estimated 2.7% ...
An asteroid capable of flattening a mid-sized city could potentially collide with Earth eight years from now, as its orbit around the sun briefly intersects the path of our planet. Named 2024 YR4 ...
The average near-Earth asteroid, such as 2019 VF 5, passes Earth at 18 km/s. The average short-period comet passes Earth at 30 km/s, and the average long-period comet passes Earth at 53 km/s. [9] A retrograde parabolic Oort cloud comet (e=1, i=180°) could pass Earth at 72 km/s when 1 AU from the Sun.
The location of 2024 YR4 qualifies it not just as any asteroid, but a near-Earth object (NEO). NEOs are defined as asteroids that hug the inner solar system, where we live, coming within 1.3 ...
