NASA warns! Massive 25-storey building sized asteroid is set to pass close to Earth on May 28 - know the speed, time and other key details
A massive asteroid named 2025 JR is drawing global attention as it speeds toward Earth for a close encounter. Roughly the size of a 25-storey building, the space rock is set to make its nearest approach on Wednesday, May 28. While it will safely bypass Earth at a distance of 4.6 million kilometers, that proximity is considered unusually close in astronomical terms. The asteroid's size and speed—combined with its Earth-crossing orbit—have sparked interest among scientists, space agencies, and skywatchers alike. Though there is no risk of collision, the flyby serves as a vivid reminder of how close—and unpredictable—near-Earth objects can be, reinforcing the need for continued monitoring and space preparedness. Asteroid 2025 JR is moving towards Earth on May 28 On 28 May 2025, Asteroid 2025 JR is set to pass by Earth at 8:40 am IST, which is about 250 feet (76 meters) across, a respectable size in space. It's an Apollo-class near-Earth object (NEO)—a class marked by asteroids that have orbits that intersect with Earth's orbit around the Sun. Being of this kind of orbital feature, these asteroids are kept under close watch for how much danger they could pose. The asteroid travels at a staggering 40,800 km/h, a speed that, were it orbiting the Earth, would finish the journey in under an hour. While 2025 JR is not deemed a "potentially hazardous asteroid" because it is below the threshold diameter of 460 feet (140 meters), it is large enough that if it were to strike the Earth, the destruction would be devastating. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Did You Know Luxury Hotel Prices in 2025 Could Be So Low?

Moving at incredible velocity, the impact energy would be equivalent to a few nuclear bombs detonating in unison. This would destroy much, trigger huge explosions, and potentially result in large-scale loss of life. One traditional historical analogy most often provided is the 1908 Tunguska asteroid or comet explosion in Siberia, where an asteroid or comet with a diameter of approximately 160–200 feet exploded in the air. The explosion flattened approximately 2,000 square kilometres of trees—a wider area than the city of Delhi—showing the destructive energy released by comparatively small space bodies. How scientists track near-Earth objects Asteroid tracking 2025 JR is a complicated process which engages the whole world. NASA's Centre for Near-Earth Object Studies coordinates the activity by collecting data from a variety of telescopes and radar stations across the globe. Amateur astronomers also participate by searching the sky for unidentified objects. This network assists researchers in forecasting near-approach and possible impact events more accurately. But despite all these developments, there are still numerous space rocks that are unknown, posing challenges to planetary defence constantly.

Asteroid 2025 HY2 to pass Earth: Date, time and speed Understanding Apollo-class asteroids How scientists worldwide work to predict space threats What if asteroid 2025 HY2 had hit Earth Produce shockwaves that ought to shatter windows and topple buildings Induce fires or local earthquakes depending on where it hits Involve enormous casualties, especially in cities Growing risk of undiscovered asteroids Also Read | Earth is continuously at risk from potential hazards in space, and perhaps the most dreaded are near-Earth asteroids—space objects with orbits bringing them close to the planet in threatening proximity. While most pass harmlessly by, each near-flyby serves as a sobering reminder of Earth's exposure. A near-Earth asteroid, namely asteroid 2025 HY2 , has just caught significant attention from scientists and space agencies all over the upcoming flyby calls to mind the ongoing need for caution, improved detection capabilities, and global cooperation to protect our world from potentially one day being a disastrous impact 2025 HY2 ought to be near its Earth-closing point on May 7, 2025, at 12:49 PM IST (07:19 UTC). It will be flying by at a remarkable velocity of approximately 48,904 kilometres per hour (approximately 30,389 miles per hour) when nearest to close and fast, the asteroid will fly by Earth by a mere 6.8 million kilometres (4.2 million miles). Though this sounds like a huge distance, by cosmic standards, it's a close 2025 HY2 is an Apollo-class asteroid, a class of asteroids with orbits that cross Earth. They circle the Sun but cross Earth's orbit, and as such, they are of particular interest to planetary defense asteroids are some of the most tightly monitored near-Earth objects (NEOs). Even though nothing is threatened in the near term, orbits are adjusted by the action of gravity or solar radiation pressure over geological time scales and formerly harmless rocks in space can become agencies like NASA and the European Space Agency (ESA), in association with global observatories, work around the clock to monitor and evaluate the threats from these objects. The Center for Near-Earth Object Studies (CNEOS) and the Minor Planet Center gather and analyze information from a global network of professional and amateur this collaborative effort, scientists can accurately predict asteroid orbits, enhance orbital simulations, and provide warning in advance of predicted collisions. But despite all these advances, the majority of small- to medium-sized asteroids are not found until near 2025 HY2 is not a "potentially hazardous asteroid" (a designation reserved for those that are larger than 140 meters in diameter), it is big enough-about 120 feet (37 meters) in diameter, the size of a Boeing it were to enter the Earth's atmosphere, the effect would be catastrophic. To give an example, the Chelyabinsk meteor that detonated in the air over Russia in 2013 was only 59 feet (18 meters) in diameter. But it hurt more than 1,500 people, broke thousands of buildings, and caused indiscriminate panic from a shockwave.A 2025 HY2 crash that is twice the magnitude of the 2013 crash can wipe out city blocks a few kilometres from ground 2025 HY2 is not the threat this time, but the close flyby is a hair-raising reminder. There are thousands of such asteroids that are yet to be discovered in our solar system, and the warning margin can be very advancement of early warning systems, planetary defense missions, and even technology to deflect an asteroid is global. NASA's DART mission-Double Asteroid Redirection Test, for example, was a historic benchmark demonstrating our ability to push the asteroid off its as these objects make their way quietly towards our planet, disaster lurks around the corner. Asteroid 2025 HY2 is merely the newest in a never-ending rotation of reminders that defending the world isn't science fiction—it's real-life insurance against extinction.
