2022 EB5
was a small, metre-sized Apollo asteroid, Apollo near-Earth asteroid that impacted Earth's atmosphere at 21:22 UTC on 11 March 2022, over the Arctic Ocean southwest of the Norway, Norwegian island Jan Mayen. With an atmospheric entry speed of , the asteroid's impact generated a 4-kiloton-equivalent Meteoroid#Fireball, fireball that was detected by infrasound from Greenland and Norway. A bright flash possibly associated with the event was reported by observers from Northern Iceland. It was discovered by astronomer Krisztián Sárneczky at Konkoly Observatory's Piszkéstető Station in Mátra Mountains, Hungary about two hours before impact. is one of only 6 asteroids to be discovered before Earth impact (along with 2014 AA, 2018 LA, , 2019 MO, and .) It was briefly listed on the Minor Planet Center's Near-Earth Object Confirmation Page under the temporary designation ''Sar2593''.

Piszkéstető Station
The Piszkéstető Station or Piszkéstető Mountain Station is an astronomical observatory in Mátraszentimre in Mátra Mountains, about northeast of Hungary's capital Budapest. It is a station of Konkoly Observatory, first built in 1958. It has the observatory code IAU code#461, 461 and IAU code#561, 561 for being used by the Szeged University and Konkoly Observatory, respectively. Instruments The observatory features four telescopes: * 60/90/180-centimetre Schmidt telescope since 1962 * 50-centimetre Cassegrain telescope since 1966 * 1-metre Ritchey–Chrétien telescope since 1974 * 40-centimetre Ritchey–Chrétien telescope since 2010 Discovery of 2022 EB5 Piszkéstető Station discovered asteroid , which later impacted earth. It is only the fifth asteroid in history to have been discovered prior to impact. This puts the station in a very short list of observatories that have achieved this feat. Several asteroids impact earth every year with enough force to be detect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Iceland
Historically, Iceland was divided into four farthings (''landsfjórðungar'', singular ''landsfjórðungur'') corresponding to the cardinal directions. These were administrative divisions established in 965 for the purpose of organising regional assemblies called farthing assemblies (''fjórðungsþing'') and regional courts called farthing courts (''fjórðungsdómar''). Each farthing held three local assemblies (usually in spring and autumn), which were each presided over by three ''goðar'' or chieftains. The North Farthing alone held four. Farthing courts would judge cases if both plaintiff and defendant belonged to the same assembly; otherwise the case was brought to the general assembly, the ''Alþingi''. Little else is known about these farthing courts and they seem to have been much more irregular than the spring and autumn assemblies. Also, in spite of the apparent regularity of three ''goðar'' per assembly and three to four assemblies per farthing, the system of rule by c ...

WT1190F
WT1190F (9U01FF6, UDA34A3, or UW8551D) was a small temporary satellite of Earth that impacted Earth on 13 November 2015 at 06:18:21.7 (± 0.1 seconds) UTC. It is thought to have been space debris from the trans-lunar injection stage of the 1998 Lunar Prospector mission. It was first discovered on 18 February 2013 by the Catalina Sky Survey. It was then lost, and reacquired on 29 November 2013. It was again discovered on 3 October 2015 by astronomer Rose Garcia with the Catalina Sky Survey 60-inch telescope, and the object was soon identified to be the same as the two objects previously sighted by the team, who have been sharing their data through the International Astronomical Union's Minor Planet Center (MPC). An early orbit calculation showed that it was orbiting Earth in an extremely elliptical orbit, taking it from within the geosynchronous satellite ring to nearly twice the distance of the Moon. It was also probably the same object as 9U01FF6, another object on a sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impact Event
An impact event is a collision between astronomical objects causing measurable effects. Impact events have physical consequences and have been found to regularly occur in planetary systems, though the most frequent involve asteroids, comets or meteoroids and have minimal effect. When large objects impact terrestrial planets such as the Earth, there can be significant physical and biospheric consequences, though atmospheres mitigate many surface impacts through atmospheric entry. Impact craters and Impact structure, structures are dominant landforms on many of the Solar System's solid objects and present the strongest empirical evidence for their frequency and scale. Impact events appear to have played a significant role in the Formation and evolution of the Solar System, evolution of the Solar System since its formation. Major impact events have significantly shaped History of the Earth, Earth's history, and have been implicated in the giant impact theory, formation of the Earth†...

Asteroid Impact Prediction
Asteroid impact prediction is the prediction of the dates and times of asteroids impacting Earth, along with the locations and severities of the impacts. The process of impact prediction follows three major steps: # Discovery of an asteroid and initial assessment of its orbit which is generally based on a short observation arc of less than 2 weeks. # Follow up observations to improve the orbit determination # Calculating if, when and where the orbit may intersect with Earth at some point in the future. In addition, although not strictly part of the prediction process, once an impact has been predicted, an appropriate response needs to be made. Most asteroids are discovered by a camera on a telescope with a wide field of view. Image differencing software compares a recent image with earlier ones of the same part of the sky, detecting objects that have moved, brightened, or appeared. Those systems usually obtain a few observations per night, which can be linked up into a very pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animation Of 2022 EB5 Around Sun
Animation is a method by which still figures are manipulated to appear as moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film. Today, most animations are made with computer-generated imagery (CGI). Computer animation can be very detailed 3D animation, while 2D computer animation (which may have the look of traditional animation) can be used for stylistic reasons, low bandwidth, or faster real-time renderings. Other common animation methods apply a stop motion technique to two- and three-dimensional objects like paper cutouts, puppets, or clay figures. A cartoon is an animated film, usually a short film, featuring an exaggerated visual style. The style takes inspiration from comic strips, often featuring anthropomorphic animals, superheroes, or the adventures of human protagonists. Especially with animals that form a natural predator/prey relationship (e.g. cats and mice, co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Near-Earth Object Confirmation Page
The Near-Earth Object Confirmation Page (NEOCP) is a web service listing recently-submitted observations of objects that may be near-Earth objects (NEOs). It is a service of the Minor Planet Center (MPC), which is the official international archive for astrometric observations of minor planets. The NEOCP was established by the MPC on the World Wide Web in March 1996. Astrometric observations of new NEO candidates are submitted by observers either through email or cURL, after which they are placed in the NEOCP for a period of time until they are confirmed to be a new object, confirmed to be an already-known object, or not confirmed with sufficient follow-up observations. If the object is confirmed as a new NEO, it is given a provisional designation and its observations will be immediately published in a ''Minor Planet Electronic Circular'' (MPEC). If the object is a recovery of an already-designated NEO on a new opposition, it will also be immediately published in an MPEC. Otherwise, ...

Minor Planet Center
The Minor Planet Center (MPC) is the official body for observing and reporting on minor planets under the auspices of the International Astronomical Union (IAU). Founded in 1947, it operates at the Smithsonian Astrophysical Observatory. Function The Minor Planet Center is the official worldwide organization in charge of collecting observational data for minor planets (such as asteroids), calculating their orbits and publishing this information via the '' Minor Planet Circulars''. Under the auspices of the International Astronomical Union (IAU), it operates at the Smithsonian Astrophysical Observatory, which is part of the Center for Astrophysics along with the Harvard College Observatory. The MPC runs a number of free online services for observers to assist them in observing minor planets and comets. The complete catalogue of minor planet orbits (sometimes referred to as the "Minor Planet Catalogue") may also be freely downloaded. In addition to astrometric data, the MPC collect ...

2019 MO
2019 MO, temporarily designated A10eoM1, was a small, harmless 3-meter near-Earth asteroid discovered by ATLAS–MLO that impacted Earth's atmosphere on 22 June 2019 at 21:25 UT. The impact of the bolide generated a 5-kiloton-equivalent explosion off the south coast of Puerto Rico which was detected by infrasound detectors. The strewn field would be spread over the Caribbean Sea. The Apollo asteroid was inbound approaching a late July perihelion (closest approach to the Sun) when it impacted Earth at 16.1 km/s. Overview The asteroid was discovered by ATLAS–MLO on 22 June 2019 and was observed four times with an observation arc of just 30 minutes, typical for ATLAS discoveries before they are followed up by other resources. With such a short observation arc, how far away (and, therefore, how large) the object is very uncertain until more data are available. Using these four observations, JPL's Scout listed the impact risk as modest, and calculated that the asteroi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2018 LA
2018 LA, also known as ZLAF9B2, was a small Apollo asteroid, Apollo near-Earth asteroid in mean diameter that impacted the atmosphere with small fragments reaching the Earth at roughly 16:44 UTC (18:44 local time) on 2 June 2018 near the border of Botswana and South Africa. It had been discovered only 8 hours earlier by the Mount Lemmon Survey, Arizona and based on hours of observations, was calculated to have a roughly 85% chance of impact likely somewhere between Australia and Madagascar. Hours later, a report arrived to the American Meteor Society that an observer from Botswana had seen a bright Fireball (meteor), fireball. Shortly after the impact, the Asteroid Terrestrial-impact Last Alert System (ATLAS) released observations obtained from Hawaii roughly 2 hours after the Mount Lemmon observations which confirmed that the asteroid had indeed impacted Earth on a grazing path as per the observed fireball. A preliminary analysis of the pre-impact evolution of this meteoroid su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2014 AA
2014 AA was a small Apollo near-Earth asteroid roughly 2–4 meters in diameter that struck Earth on 2 January 2014. It was discovered on 1 January 2014 by Richard Kowalski at the Mount Lemmon Survey at an apparent magnitude of 19 using a reflecting telescope at Mount Lemmon Observatory. 2014 AA was only observed over a short observation arc of about 70 minutes, and entered Earth's atmosphere about 21 hours after discovery. Nonetheless it remains one of only a few asteroids observed before impact (see Asteroid impact prediction). Entry Using a poorly determined orbit, the JPL Small-Body Database listed a 3-sigma solution with impact occurring around 2 January 2014 02:33 UT ± 1 hour and 5 minutes. The Minor Planet Center listed impact as occurring around 2 January 2014 05:00 UT ± 10 hours. Independent calculations by Bill Gray, the Minor Planet Center and Steve Chesley at the Jet Propulsion Laboratory verified that impact was virtually certain. It entered the atmosphere goi ...
