A new study warns that dense clusters of debris from the Taurid meteor stream, associated with Comet Encke, could pose a threat to Earth in 2032 and 2036 due to potential impacts from larger fragments, but with proper observation and mitigation, the risk can be managed.
NASA has confirmed that the object dubbed Earth's 'second moon' is actually a quasi-moon, an asteroid that orbits the sun in near-lockstep with Earth, and not a true moon. Known as 2025 PN7, it has likely been near Earth for about 60 years and will remain so until around 2083, but it has minimal gravitational impact due to its small size.
Scientists have discovered a new near-Earth asteroid, 2025 SC79, which is challenging to observe due to its proximity to the Sun and its orbit entirely within Venus's orbit. This asteroid, about 700 meters in diameter, completes an orbit around the Sun in 128 days and poses potential impact risks, highlighting the importance of studying such elusive objects for planetary defense.
A small asteroid named 2025 TF passed closer to Earth than many satellites, flying over Antarctica at just 265 miles altitude on October 1, 2025. It was detected shortly after its passage by the Catalina Sky Survey and ESA's Planetary Defence Office, highlighting the challenges in tracking small near-Earth objects. The asteroid posed no significant threat but could have created a meteor if it had entered Earth's atmosphere. Another small asteroid, 2025 TQ2, also passed near Earth the following day.
A large asteroid, 2025 FA22, nearly the size of a skyscraper, will pass close to Earth at over 24,000 mph on September 18, but poses no threat according to NASA and ESA. The asteroid, detected in March, offers a rare opportunity for study and highlights the importance of monitoring potentially hazardous objects in space.
A massive asteroid, 427 to 951 feet in size and traveling at over 24,000 mph, will pass close to Earth on September 18, but poses no threat according to NASA and ESA. The asteroid, named 2025 FA22, was discovered in March and is considered potentially hazardous due to its size and proximity, but updated measurements have ruled out collision risk. It offers a rare opportunity for close study and highlights the importance of monitoring near-Earth objects.
NASA warns of two close-passing asteroids tomorrow: 2025 QV5, a small 35-foot asteroid passing at 500,000 miles, and 2025 QD8, a 71-foot asteroid passing at 136,000 miles. Neither pose a threat to Earth, but both are of scientific interest, with the larger one making its closest approach in over a century.
An asteroid approximately 71 feet wide will pass close to Earth on September 3, providing a rare opportunity for observation and study, with a livestream available for viewing. The asteroid's closest approach will be about 136,000 miles away, and it offers valuable insights into near-Earth objects and planetary defense efforts.
A recent study compares the likelihood of dying from an asteroid impact to other causes like lightning and car crashes, finding that while asteroid impacts are rare, they are more likely than some other deadly events, highlighting Earth's vulnerability and ongoing planetary defense efforts.
NASA and international space agencies are monitoring asteroid 2025 OL1, which will pass Earth at a safe distance of 1.29 million kilometers on July 30, 2025. Although it is classified as potentially hazardous due to its size, there is no threat to Earth. These flybys serve as important opportunities to improve detection and tracking systems, enhancing planetary defense strategies for future, potentially more dangerous objects.
NASA announced that the asteroid 2025 OW, about the size of a plane, will pass by Earth at a safe distance of approximately 390,000 miles on July 28, traveling at nearly 47,000 mph. Experts emphasize that such close approaches are routine and pose no threat, with NASA tracking its orbit precisely. The article also highlights the upcoming close encounter with asteroid Apophis in 2029, which will pass closer to Earth but still safely.
NASA reports that a plane-sized asteroid, 2025 OW, will pass Earth at a safe distance of about 393,000 miles on July 28, a routine event with no threat to our planet, as NASA continuously monitors such objects and emphasizes their rarity and safety.
A new Chilean observatory, the Vera C. Rubin Observatory, is set to revolutionize our understanding of the solar system by discovering millions of asteroids, comets, and other objects, with the help of the Sorcha software that predicts its findings, significantly expanding our knowledge of near-Earth objects and the solar system's structure.
Scientists warn that at least three large asteroids co-orbiting with Venus are hidden from view due to the Sun's glare and pose a potential impact threat to Earth within weeks, highlighting the need for dedicated space probes to better detect these hazardous objects.
A new study warns of a hidden population of Venus co-orbitals—asteroids sharing Venus's orbit—that could pose a threat to Earth, highlighting the need for space-based observatories to detect these elusive objects and improve planetary defense efforts.
