A small asteroid, 2025 QV5, approximately the size of a bus, will pass within 500,000 miles of Earth on September 3, its closest approach in nearly 100 years, and will not come this close again until 2125. It poses no threat to Earth but is being studied by NASA to better understand near-Earth objects.
Potentially hazardous asteroid 2013 NK4, between 400 and 1,000 meters across, made a close approach to Earth, passing harmlessly by more than eight times the distance to the Moon. NASA imaged the asteroid and discovered it may be a contact binary asteroid. While it made its closest approach on April 15, it should still be visible with a telescope on April 16 and 17.
A "potentially hazardous" 2,000-foot-wide asteroid, 2013 NK4, has made its closest approach to Earth, but poses no threat. It will be visible via amateur telescopes until April 17. Despite its classification, it is not expected to impact Earth. Astronomers are tracking it with radio telescopes to capture specialized radar images. The asteroid orbits the sun every 378 days and will return for another flyby in 2025. This is the closest approach in at least 125 years, and it won't be visible again for over 30 years.
A small asteroid, named 2024 GJ2, is set to make a close approach to Earth, passing within 0.03 Lunar Distances or about 12,298 kilometers from our planet. Measuring between 2.2 to 4.9 meters, it was discovered in April this year and will make its closest approach at 18:28:42 UTC. Despite being tracked by NASA, it is not considered a concern as it is too small to pose a threat.
The "potentially hazardous" asteroid 2008 OS7, about the size of a football stadium, will make its closest approach to Earth in over 100 years, passing by at a distance of 1.77 million miles. Despite its classification, it poses no threat of impact. NASA has identified around 25,000 potentially hazardous asteroids, with one expected to hit Earth every 20,000 years. The asteroid's highly elliptical orbit causes its distance from Earth to vary widely during close approaches.
A football stadium-size asteroid named 2008 OS7 will make its closest approach to Earth for more than 100 years on Feb. 2, passing by at a distance of around 1.77 million miles. Despite being classified as "potentially hazardous," it poses no threat of impact. The asteroid's highly elliptical orbit means its distance from Earth varies widely during close approaches. NASA has identified around 25,000 potentially hazardous asteroids, with one expected to hit Earth every 20,000 years.
NASA has revealed that an asteroid, designated as Asteroid 2021 CZ2, is expected to pass Earth at a close distance today, hurtling at a speed of 51636 kilometers per hour and measuring almost 350 feet wide. Belonging to the Aten group of asteroids, it will pass Earth again on July 13 at a greater distance. These space rocks, remnants from the early solar system, can be knocked out of their main belt orbits by Jupiter's gravity or close encounters with planets, posing potential threats to Earth.
NASA has announced that an aircraft-sized asteroid, named Asteroid 2010 XF3, will pass by Earth today at a distance of 7.4 million kilometers. Moving at a speed of approximately 14,304 kilometers per hour, the asteroid belongs to the Aten group of Earth-crossing Near-Earth Asteroids (NEAs). Although nearly 150 feet wide, it is not designated as a Potentially Hazardous Asteroid.
The colossal cryovolcanic comet, 12P/Pons-Brooks, has experienced its fourth explosive outburst, becoming as bright as the Elliptical Galaxy. This comet, known for its devil-like horns, is approximately 18 miles in diameter and exhibits volcanic behavior by releasing gas and ice instead of molten rock. It is on a trajectory to make its closest approach to Earth in June 2024, posing no threat. Comets like 12P/Pons-Brooks offer insights into the early solar system and the origins of life, as they consist of frozen gases, rock, and dust.
NASA has announced that five asteroids are approaching Earth in the coming days. The largest asteroid, 2009 UG, measures between 190 and 426 feet in width and will pass by Earth at a distance of 2.3 million kilometers. The other asteroids include 2023 SE4, 2023 RF9, 2023 SC4, and 2023 SA6, ranging in size from 45 to 141 feet wide, and will pass by Earth at distances ranging from 2 to 6.2 million kilometers.
NASA has announced that a 45-foot asteroid named 2023 SE4 is approaching Earth at a speed of 16,509 kilometers per hour and will make a close approach tomorrow, September 29, 2023. However, it poses no threat to Earth as it falls below the size threshold of 492 feet for potentially hazardous objects.
A newly discovered asteroid, about 6.5 feet wide, passed within 2,500 miles of Earth, five times closer than GPS satellites. Designated C9FMVU2, the asteroid posed no danger to Earth due to its small size. If it had collided with the planet, it would have burned up in the atmosphere, causing a fireball. The close pass altered the asteroid's trajectory due to Earth's gravitational pull. Astronomers are working to map out near-Earth asteroids to prevent unexpected collisions, and space agencies have plans to divert potentially hazardous rocks.
NASA has revealed that five asteroids are hurtling towards Earth and will make close approaches in the coming days. The largest asteroid, 1988 EG, is approximately 3000 feet wide and will come as close as 6 million kilometers to Earth on August 23. The other asteroids include 2023 OE5, 2023 PC, 2022 CP1, and 2011 QJ21, ranging in size from 38 to 130 feet wide, and will pass by Earth on August 14, 17, and 19, respectively.
NASA has issued a warning about a 150-foot asteroid, designated as Asteroid 2023 OD5, which is expected to make a close approach to Earth today. While it will come close, it is not expected to impact the surface. The asteroid will pass by Earth at a distance of around 5.3 million kilometers and belongs to the Aten group of Earth-crossing Near-Earth Asteroids. NASA has already tested a method of asteroid diversion and has missions in place for early warning systems. Although no asteroid is expected to impact Earth in the next 100 years, countermeasures for planetary defense remain important.
NASA has issued a warning about Asteroid 2023 MD2, a 150-foot-wide asteroid that will pass extremely close to Earth today at a distance of approximately 2.1 million kilometers. While not a planet killer, the asteroid is still significant in size and is approaching Earth at a breakneck speed of 30,362 kilometers per hour. This close approach highlights the importance of continued technological development in asteroid detection and monitoring programs to ensure the safety of our planet from potential impacts.
