    Earth has captured a tiny object from its orbit around the Sun and will keep it as a temporary satellite for a few months before it escapes back to a solar orbit. But the object is likely not an asteroid; it's probably the Centaur upper stage rocket booster that helped ...

    A small near-Earth asteroid (or NEA) will briefly visit Earth's neighborhood on Thursday, Sept. 24, zooming past at a distance of about 13,000 miles (22,000 kilometers) above our planet's surface. The asteroid will make its close approach below the ring of geostationary satellites orbiting about 22,000 miles (36,000 kilometers) away ...

    A large near-Earth asteroid will safely pass by our planet on Wednesday morning, providing astronomers with an exceptional opportunity to study the 2-kilometer-wide (1.5-mile-wide) object in great detail.
  • 2020-04-28
    A relatively small asteroid, about 4 to 8 meters in diameter, will fly safely past Earth just before 3pm today, Apr. 28 (Eastern U.S. time). NASA is tracking the object, but orbit calculations ruled out any chance that the near-Earth object could pose a threat to our planet.
  • 2020-02-27
    A small object, presumed to be a tiny asteroid, has been discovered in a distant orbit about the Earth, a highly unusual circumstance, since asteroids normally orbit the Sun. The new “mini-moon” has been given the asteroid designation 2020 CD3, but in view of its strange orbit, there is a ...
  • 2019-09-12
    A newly discovered comet has excited the astronomical community this week because it appears to have originated from outside the solar system. The object - designated C/2019 Q4 (Borisov) - was discovered on Aug. 30, 2019, by Gennady Borisov at the MARGO observatory in Nauchnij, Crimea. The official confirmation that ...

    In 2017, astronomers discovered an object passing through our solar system which most concluded was the first interstellar asteroid. Jeff Foust reviews a book by a Harvard astronomer who tries to make the case that the object is instead an alien artifact.
  • 2020-11-30
    In April 2029, the asteroid Apophis will pass close to the Earth, posing no threat of impact but instead offering an opportunity for scientists. Jeff Foust reports on discussions at a recent workshop on the potential missions that could be flown during the flyby and the rationales for them.
  • 2020-11-23
    Five years ago this week, President Obama signed into law a bill that granted companies rights to space resources they extracted. Jeff Foust describes how that effort, intended to enable asteroid mining, has evolved to support the use of lunar resources as part of Artemis and related initiatives.
  • 2020-10-19
    On Tuesday, NASA's OSIRIS-REx spacecraft will attempt to touch down on the surface of asteroid Bennu and collect samples for return to Earth. Jeff Foust reports on how this effort, already technically challenging, has turned out to be even more difficult than originally expected.

    If you stumble upon an unusual rock that could be a meteorite, do not place a magnet on it to see if it's magnetic—you'd end up erasing 4.5 billion years of magnetic history. Meteorites are remnants of our solar system's first protoplanets and, in some cases, retain a record of ...

Meteoriti.LV vietne tiks pakāpeniski papildināta ar plašu pamatinformāciju par meteorītiku un ar to saistitām astronomijas nozarēm. Uzzināsiet, vai "meteorīti dabā sastopami retāk par dimantiem", cik tie ir veci un kāda ir to izcelsme. Atradīsiet atbildes uz jautājumiem: Vai meteorīti ir bīstami? Kādi meteorīti atrodami Latvijā un kur tos var apskatīt? Vai Latvijā ir vērts meklēt meteorītus? Ko meteorītu izpēte pastāsta mums par Zemes un Saules sistēmas izcelšanos? Ceram, ka tas radīs vēlmi arī jums pašiem novērot Zemes kosmiskos viesus - meteorus, un, varbūt, pat kļūt par īstiem meteorītu medniekiem!
Veiksmīgu novērošanu!
