2022 EB5
was a small, two-metre Apollo near-Earth asteroid that disintegrated in Earth's atmosphere at 21:22 UTC on 11 March 2022, over the Arctic Ocean southwest of the Norwegian island Jan Mayen. With an atmospheric entry speed of , the asteroid's impact generated a 4-kiloton-equivalent 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 the fifth asteroid discovered before impacting Earth. It was briefly listed on the Minor Planet Center's Near-Earth Object Confirmation Page under the temporary designation ''Sar2593''.

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 simil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2019 MO
2019 MO, temporarily designated A10eoM1, was a small, harmless 3-meter near-Earth asteroid discovered by Asteroid Terrestrial-impact Last Alert System, ATLAS–MLO that Impact event, impacted Earth's atmosphere on 22 June 2019 at 21:25 Universal Time, 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 Asteroid Terrestrial-impact Last Alert System, 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 avai ...

2018 LA
2018 LA, also known as ZLAF9B2, was a small 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. 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 suggests that it may be part of a d ... [...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 ...

Impact Event
An impact event is a collision between astronomical objects causing measurable effects. Impact events 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 Biosphere, biospheric consequences, as the impacting body is usually traveling at several kilometres per second (km/s), with a minimum impact speed of 11.2 km/s (7.0 mi/s) for bodies striking Earth. Atmosphere, While planetary atmospheres can mitigate some of these impacts through the effects of atmospheric entry, many large bodies retain sufficient energy to reach the surface and cause substantial damage. This results in the formation of Impact crater, impact craters and Impact structure, structures, shaping the dominant landforms found across various types of solid objects found in the Solar System. Their prevalence and ubiquity pres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The usual purpose of predicting an impact is to direct an appropriate response. 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 preliminary orbit determination. This predicts approximate positi ...

Animation Of 2022 EB5 Around Sun
Animation is a filmmaking technique whereby still images are manipulated to create moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film. Animation has been recognised as an artistic medium, specifically within the entertainment industry. Many animations are either traditional animations or computer animations made with computer-generated imagery (CGI). Stop motion animation, in particular claymation, has continued to exist alongside these other forms. Animation is contrasted with live action, although the two do not exist in isolation. Many moviemakers have produced films that are a hybrid of the two. As CGI increasingly approximates photographic imagery, filmmakers can easily composite 3D animations into their film rather than using practical effects for showy visual effects (VFX). General overview Computer animation can be very detailed 3D animation, while 2D computer an ... [...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. Otherwis ...
