Feb 7, 2025 · Overview. Asteroid 2024 YR4 is a near-Earth asteroid, meaning it is an asteroid in an orbit that brings it into Earth’s region of the Solar System. 2024 YR4 is estimated to be about 130 to 300 feet (40 - 90 meters) wide and has a very …

1 day ago · NASA expects the impact probability to continue to evolve as new observations of asteroid 2024 YR4 are made over the coming days and weeks. These recent observations have further constrained the uncertainty around the asteroid’s trajectory, and the yellow dots in the above graphics represent possible locations of the asteroid on Dec. 22, 2032.

Feb 7, 2025 · Most asteroids can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt. Asteroids range in size from Vesta – the largest at about 329 miles (530 kilometers) in diameter – to bodies that are less than 33 feet (10 meters) across.

Feb 7, 2025 · NASA’s James Webb Space Telescope will also observe the asteroid in March 2025 to better assess the asteroid’s size. Currently the asteroid is estimated to be 130-300 feet across. As more observations of the asteroid’s orbit are obtained, its impact probability will become better known.

Jan 29, 2025 · NASA analysis of a near-Earth asteroid, designated 2024 YR4, indicates it has a more than 1% chance of impacting Earth on Dec. 22, 2032 – which also means there is about a 99% chance this asteroid will not impact. Such initial analysis will change over time as more observations are gathered.

This interactive visualization uses data from JPL's Center for Near Earth Object Studies (CNEOS), which computes high-precision orbits for Near-Earth Objects (NEOs) in support of NASA’s Planetary Defense Coordination Office.

Feb 14, 2025 · NASA's analysis of near-Earth asteroid 2024 YR4, which is estimated to be about 130 to 295 feet (40 to 90 meters) wide, indicates it has a more than 1% chance of impacting Earth on Dec. 22, 2032. Learn More

The Asteroid Watch dashboard tracks asteroids and comets that will make relatively close approaches to Earth. The dashboard displays the date of closest approach, approximate object diameter, relative size and distance from Earth for each encounter.

1 day ago · A recently discovered asteroid, named 2024 YR4, is now the riskiest asteroid ever detected. On Tuesday, NASA calculated that the space rock had a 3.1% chance of hitting Earth in 2032, while the ...
