Asteroid 2003 MH4, Flying At 14 Kilometres Per Second, Will Miss Earth By This Much On May 24
Last Updated: According to NASA, the asteroid will come within 6.68 million kilometres of Earth, which the space agency says is a close shave. An asteroid nearly the size of three football fields is heading toward Earth for what astronomers are calling a 'close approach", prompting heightened surveillance by NASA's planetary defence teams. Named Asteroid 2003 MH4, this 335-metre-wide object is set to pass near Earth on May 24, 2025, travelling at a blistering speed of 14 kilometres per second – fast enough to cover the distance between Delhi and Mumbai in under a minute. According to NASA's Jet Propulsion Laboratory (JPL), the asteroid will come within 6.68 million kilometres of Earth. While that might sound comfortably distant in everyday terms, in the vast realm of space, it's a narrow miss. NASA classifies any object over 150 metres wide and approaching within 7.5 million kilometres as a 'Potentially Hazardous Asteroid". 2003 MH4 meets both criteria, making it a serious subject of scrutiny by scientists at the Centre for Near Earth Object Studies (CNEOS). This massive space rock is part of the Apollo group, a class of Earth-crossing asteroids named after the first of their kind discovered in 1932. With over 21,000 known members, the Apollo group includes numerous objects whose orbital paths intersect with Earth's, occasionally raising alarms about future impacts. NASA continues to track these celestial wanderers using a combination of ground-based telescopes and sophisticated computer models. Although there is no imminent danger of 2003 MH4 striking Earth during this flyby, experts remain cautious. Its orbit, combined with its considerable size, warrants close monitoring. Scientists note that the asteroid completes a full orbit around the Sun every 410 days, increasing the chances of future close encounters. Should its trajectory shift – even slightly due to gravitational interactions or other factors – future flybys could pose a greater risk. This isn't the only asteroid keeping scientists on their toes. Asteroid Apophis, once feared to impact Earth in 2029, has since been cleared of that risk after extensive observation. Meanwhile, other near-Earth objects like 2024 YR4 and 2025 FA22 remain under close study. Particularly, 2025 FA22 is expected to come uncomfortably close in the year 2089, though current models estimate the probability of collision at a mere 0.01%. As May 24 approaches, scientists around the world will be watching 2003 MH4 closely; not because it poses an immediate threat, but because it reminds us of the precarious cosmic neighbourhood we inhabit.

New asteroid as big as The Gherkin added to Earth threat-list
New asteroid as big as The Gherkin added to Earth threat-list Asteroid FA22 has been placed at number three on the risk list by the European Space Agency Composite image showing an asteroid the size of The Gherkin The European Space Agency has identified another asteroid as a potential collision risk for Earth, placing it in the top three hazards for the planet. 2025 FA22 is 656 feet or 200 meters in diameter - as tall as The Gherkin in London or New York's Trump Tower - and will approach Earth on September 19, 2089. The asteroid was found by the Panoramic Survey Telescope and Rapid Response System 2 (Pan-STARRS 2) in Hawaii on March 29 and has been assigned a rating of above -3 on the Palermo Scale. The Palermo Technical Impact Hazard Scale is used by astronomers to assess the risk of an asteroid or comet impacting Earth. It combines both the probability of impact and the potential energy of the impact to provide a single risk score. The asteroid's score means 'not currently concerning'. It has a Torino Scale score of close to 1, meaning 'no cause for concern'. FA22 will make a relatively close pass on September 18, 2025 before returning in 2089. After the close pass, scientists will have a better idea of the asteroid's make-up and trajectory. There are 1,782 objects on the ESA 'watchlist' as potential threats to Earth. 2025 FA 22 is currently third on that list, after 2023 VD3 - due between 2034 and 2098, and 2008 JL3 - due between 2027 and 2122. None of the asteroids has a high potential of hitting the planet at present. Article continues below An asteroid named Apophis, officially designated 99942 Apophis, is due to pass closer to the Earth than some satellites orbit on April 13, 2029. Apophis was discovered on June 19, 2004, by astronomers at Kitt Peak National Observatory, Arizona. It is 340 meters (1,100 feet) in diameter - large enough to cause major regional damage if it hit Earth - and has been named after Apophis, the ancient Egyptian god of chaos. In late 2004, astronomers calculated a relatively high probability (up to 2.7%) that Apophis could impact Earth on April 13, 2029 — an unprecedented concern for an object of its size. It briefly reached a level 4 on the Torino Scale — the highest ever recorded. (Level 4 means it merited attention from astronomers and potentially civil authorities.) Article continues below Impact has been ruled out for the foreseeable future, but it will pass just 19,000 miles from the Earth making it visible to the naked eye. The asteroid 2024 YR4 recently garnered significant attention due to initial assessments suggesting a potential impact with Earth. Early observations indicated up to a 3.1% chance of Earth impact on 22 December 2032, the highest ever recorded for an asteroid of this size (40 to 100 meters). The impact risk has been downgraded to nearly zero, and the asteroid has been removed from ESA's risk list.
