    In a study released Wednesday, NASA researchers used precision-tracking data from the agency's Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft to better understand movements of the potentially hazardous asteroid Bennu through the year 2300, significantly reducing uncertainties related to its future orbit, and improving scientists' ability to determine ...

    After its discovery in 2004, asteroid 99942 Apophis had been identified as one of the most hazardous asteroids that could impact Earth. But that impact assessment changed as astronomers tracked Apophis and its orbit became better determined.Now, the results from a new radar observation campaign combined with precise orbit analysis ...

    The largest asteroid predicted to pass by our planet in 2021 will be at its closest on March 21, providing astronomers a rare opportunity to get a good look at a rocky relic that formed at the dawn of our solar system.Called 2001 FO32, the near-Earth asteroid will make its ...

    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 ...

    Near Earth Asteroids, or NEAs, pass by our home planet all the time. But an SUV-size asteroid set the record this past weekend for coming closer to Earth than any other known NEA: It passed 1,830 miles (2,950 kilometers) above the southern Indian Ocean on Sunday, Aug. 16 at 12:08 ...

    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 ...

    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 ...

    Two days after Christmas back in 1972, a meteor headed west across the sky over southwest Paraná State in Brazil. Described as an “airplane on fire” and a “flying torch” the bright light broke up and left a trail of smoke that floated in the cloudless morning sky for more than 15 minutes. Machine guns … The post Turbid Glass from a King: The Ipiranga Brazil Meteorite first appeared on Meteorite Times Magazine.

    Over the years I have written about meteorites that I have sent off for classification. Repeatedly the question “How can I get a meteorite classified?” has been asked.

    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.

Kopš meteorītikas zinātnes dzimšanas pagājuši 227 gadi.
Pirmais zināmais meteorīts Latvijas teritorijā nokrita pirms 201 gada.
Otrais zināmais meteorīts Latvijas teritorijā nokrita pirms 158 gadiem.
Trešais zināmais meteorīts Latvijas teritorijā nokrita pirms 157 gadiem.
Pēdējais zināmais meteorīts Latvijas teritorijā nokrita pirms 131 gada.
Pirmais meteorītikai veltītais muzejs Latvijā dibināts pirms 6 gadiem.


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!
