"NASA Warns: 5 Asteroids to Pass Dangerously Close to Earth in Next 48 Hours"

NASA has identified five asteroids that will pass by Earth over the next two days, with the largest ones being the size of a plane. These asteroids are expected to safely fly past our planet without causing any harm. NASA tracks the trajectories of near-Earth objects and classifies any large object within 4.65 million miles of Earth as "potentially hazardous." While the approaching asteroids pose no threat, smaller asteroids can still be dangerous. Space agencies are working on ways to deflect dangerous asteroids, with recent successful tests of redirecting asteroids off course.

Hubble telescope captures boulders launched into space by NASA's asteroid-smashing mission

The Hubble Space Telescope has captured images of a swarm of boulders that were knocked loose from the targeted asteroid, Dimorphos, during NASA's DART mission. DART, which stands for Double Asteroid Redirection Test, aimed to alter the orbit of Dimorphos around a larger asteroid, Didymos, as part of developing a planetary defense system. The impact produced a cloud of boulders, possibly originating from the asteroid itself, and provides valuable insights into space rock impacts and potential defense mechanisms for Earth. The boulders range in size from three to 22 feet and are drifting away from their source at a slow speed. Further observations may help determine their precise trajectories and launch directions.

Multiple Asteroids Set to Pass Close to Earth in Coming Days

A bus-sized asteroid named 2023 HV5 will pass by Earth on Thursday, while three larger asteroids are expected to pass by on Friday. NASA's planetary defense system has discovered 31,831 asteroids in total, with 103 found to be passing Earth closer than the moon in the last year. Over 10,000 asteroids discovered were larger than 140 metres, with an estimated 15,000 left to be found.
