Asteroid 2024 YR4 Earth Impact

Asteroid 2024 YR4, once a concern for potentially striking Earth in 2032, now has a very low chance of impact after recent observations by astronomers.

Asteroid 2024 YR4 Threat Assessment

NASA is monitoring a hazardous asteroid named 2024 YR4, which is 150-300 feet wide. Astronomers are assessing the likelihood of it impacting Earth.

Potential Impact of Asteroid 2024 YR4 on Earth

A newly identified space rock, potentially as big as a football field, has a 1.6% chance of crashing into Earth on Dec. 22, 2032, according to the International Asteroid Warning Network. The asteroid, known as 2024 YR4, could cause considerable localized damage if it impacts a populated area. The asteroid is estimated to be between 40 to 90 meters in diameter.

Asteroid Threat to Earth

Astronomers warn that an asteroid the size of a football pitch could potentially hit Earth in 7 years, with a 1.2% chance of collision. The asteroid, named 2024 YR4, is currently the highest risk on the asteroid risk list. NASA scientists are considering various methods to prevent a collision, including crashing a sacrificial spacecraft into the asteroid or using nuclear warheads on larger asteroids.

The Perseverance rover captures footage of Phobos passing in front of the sun on Mars. An asteroid that has been orbiting Earth will peel away soon. NASA will observe the asteroid using a radar antenna in January. The asteroid will return in 2055, making a temporary lap around Earth.

NASA's DART Mission Reshapes Asteroid Moon Dimorphos

NASA's DART mission reshaped an asteroid moon, Dimorphos, causing it to change shape from a hamburger to a football and potentially setting it on a chaotic new path. The impact may have also caused Dimorphos to tumble unpredictably, challenging previous beliefs about asteroid moons. The success of the mission opens new possibilities for planetary defense strategies.

NASA's Hypothetical Exercise on Potential Asteroid Collision

NASA conducted a hypothetical exercise and found that an asteroid has a 72 percent chance of hitting Earth in 2038. The plan to combat the asteroid has gaps, and public awareness methods are not fully developed. The exercise highlighted the need for better preparation and coordination in case of an asteroid strike.

NASA's Double Asteroid Redirection Test (DART) mission

NASA's DART mission successfully changed the trajectory and shape of the asteroid Dimorphos, demonstrating the ability to protect Earth from potential collisions.
