NASA Tracks Five Large Asteroids Passing Earth May 27-28

In late May 2025, several asteroids, including the notably large 2025 JR, will closely approach Earth, prompting significant attention from NASA and astronomers worldwide. Asteroid 2025 JR, about 250 feet across and traveling at approximately 40,800 km/h, will pass safely at a distance of 4.6 million kilometers, an unusually close proximity that underscores the importance of continuous monitoring. Although not classified as potentially hazardous due to its size being below 460 feet, a collision would have devastating effects comparable to multiple nuclear explosions, similar to the 1908 Tunguska event. Alongside 2025 JR, other asteroids such as 2025 JP, 2025 KX3, and several others ranging from bus to building size will fly by between May 27 and 28, some at distances closer than the Moon, highlighting the scale and diversity of near-Earth objects under surveillance. NASA's Asteroid Watch Dashboard and global observatories are actively tracking these objects, emphasizing the critical need for planetary defense readiness despite no imminent collision risk. Overall, these events serve as a reminder of the ongoing necessity for vigilance in detecting and analyzing near-Earth objects to mitigate potential future threats.
