    Scientists believe Kamo’oalewa will remain alongside Earth for millions of years. Could a near-Earth asteroid be a piece of the moon? Astronomers from the University of Arizona believe so. In a captivating cosmic discovery, scientists uncovered evidence suggesting that a near-Earth asteroid called Kamo’oalewa might be a fragment of the moon. The finding challenges previous assumptions about the origins of near-Earth asteroids and could have significant implications for our understanding of celestial bodies close to our planet.
  • Asteroids could be approaching Earth undetected as NASA scientists find a danger zone that allows space rocks to 'sneak up' on telescopes because of a quirk of the planet's daily rotation

    This is the warning of NASA-funded experts who investigated how telescopes nearly missed a 328-feet-wide asteroid that came within 43,500 miles of Earth back in 2019. The space rock, dubbed '2019 OK', was the first object of its size to get that close to our planet since 1908 — but it was only spotted 24 hours before its closest approach. The reason, the team determined, is because it was moving towards us in such a way that its motion across the night sky was counteracted by the Earth's spin. Thus — to early warning systems like Pan-STARRS1 at Hawaii's Haleakala...

    A large asteroid visits our fair corner of the solar system this week, and with a little planning you may just be able to spot it. Near Earth Asteroid (NEA) 285263 (1998 QE2) will pass 6.2 million kilometres from the Earth on Friday, May 31st at 20:59 Universal Time (UT) or 4:59PM EDT. Discovered in 1998 during the LIncoln Near-Earth Asteroid Research (LINEAR) sky survey looking for such objects, 1998 QE2 will shine at magnitude +10 to +12 on closest approach. Estimates of its size vary from 1.3 to 2.9 kilometres, with observations by the Spitzer Space Telescope in 2010...
  • Asteroid Poses Tiny Danger, but It May Be Lured Away

    From a human perspective, Earth-crossing asteroids can have good timing or bad timing. Good timing is when the asteroid and the Earth don't meet. Bad timing is when they do. Astronomers say that a 1,000-foot diameter asteroid discovered last year may have bad timing. There is a slight possibility that the rock, 99942 Apophis, will hit Earth in 2036 after coming within about 20,000 miles in 2029. A collision could cause regional devastation on a scale far worse than last year's tsunami. "The most likely thing is that it is not going to be a threat," said Rusty Schweikart, the...
