Huge Asteroid Apophis Flies By Earth on Friday the 13th in 2029. The most important observations of Apophis will come during its close Earth flyby in 2029. Scientists around the world will study the asteroids size, shape, composition and possibly even its interior. Apophis is a 1,120-foot-wide (340-meter-wide) asteroid. Indeed, one asteroid estimated to have been around a kilometer in size struck Southeast Asia around 800,000 years ago, according to a study from Curtin University. (2022, July 7). The excitement of Apophis' discovery turned to concern when researchers calculated just how close the asteroid's orbit would bring the space rock to Earth.

However, a more immediate possible solution was proposed by Airbus, which would see TV satellites essentially hijacked and repurposed in order to deflect an asteroid and this solution could only take a few months to get ready and launch. Its approach will be so close to earth, that our gravity will alter its speed and trajectory according to earthsky.org. NASA confirmed that on 13 April 2029, the asteroid Apophis will pass less than 20,000 miles (32,000 kilometres) from Earths surface, which is closer than the distance of geosynchronous satellites. There isn't anything like it in the geological record of our planet. 9 interesting facts (that don't blame the farmers), Kansas high school basketball state qualifiers: Find winning boys, girls teams moving on, Skeletal remaind found at Oslo Road boat ramp believed to be of Susy Tomassi. (2021, March 25) NASA Jet Propulsion Laboratory (JPL); JPL. An artist's depiction of the OSIRIS-REx spacecraft studying the asteroid Apophis. Weve never seen something that large get that close, said Lance Benner, a principal scientist at JPL. A 2068 impact is not in the realm of possibility anymore, and our calculations dont show any impact risk for at least the next 100 years, said Davide Farnocchia of NASAs Center for Near-Earth Object Studies (CNEOS), which is managed by NASAs Jet Propulsion Laboratory in Southern California. Although Apophis will not hit Earth anytime soon, the asteroid will make a close encounter with our planet on April 13, 2029, when it will pass within just 19,000 miles (31,000 kilometers). For further comparison, the last known significant asteroid impact was on February 15, 2013, when an asteroid exploded in the air above Chelyabinsk, Russia. Shortly after April 13, the craft by then renamed OSIRIS-APophis EXplorer, or OSIRIS-APEX will steer toward the asteroid until it is drawn into its orbit, eventually getting close enough to collect a sample from its surface. The forecast, issued by the All-Russian Institute for Research of Civil Defence of the Emergencies Ministry of Russia, says that the asteroid will skim past Earth at a distance at which geostationary satellites are placed in orbit (approximately 35,700 km). The asteroidnicknamed Apophiswill be as close as Meghan earned an MA in science journalism from New York University and a BA in classics from Georgetown University, and in her free time she enjoys reading and visiting museums.

But, they note that Apophis has a small chance of hitting Earth sometime in 2068. "If the impact occurs in the ocean, it can generate hazardous tsunamis; on land, a lot more ejected dust is produced," Collins told Space.com in an email. From the visual observations taken in 2004, researchers at CNEOS calculated that there was around a 2.7% chance that the object would hit Earth in 2029. Originally the asteroid was designated 2004 MN4 but after being further studied it gained the permanent number of 00042, and then subsequently was given the name Apophis by its discoverers. After completing its current mission to gather a sample of asteroid Bennu in 2023, OSIRIS-REx will be renamed OSIRIS-APophis EXplorer (OSIRIS-APEX). Also known as asteroid 99942, the near-Earth object is estimated to be about 1,100 feet (340 meters) across and could cause serious damage to the planet's surface if it were to hit. In a nod to its horrifying potential, they named it Apophis, after an Egyptian god of chaos. Cross that particular doomsday scenario off the list. As described by NASA, the April 13, 2029 flyby of asteroid Apophis will be one for the record books, because of the proximity and the large size of asteroid Apophis.

The bad news: an asteroid as big as the Eiffel Tower and named after a god of chaos is heading towards the Earth. Related: Dinosaur-killing asteroid triggered mile-high tsunami that spread through Earth's oceans, Collins estimates that if Apophis were to strike Earth at 45,000 mph (72,000 km/h) the average speed of asteroid impacts the energy released would be about 10 billion, billion joules (a 1 followed by 19 zeros). The massive asteroid known as 99942 Apophis was once considered among the most dangerous asteroid in space, with the potential to strike Earth very high. Tiny asteroids like 2020 SW approach Earth this closely several times every year and aren't a threat: https://t.co/xKWtzxLI7Q pic.twitter.com/FpkY77zibw. The probe is set to spend 18 months studying the infamous near-Earth asteroid Apophis, watching the rock during a close, but very safe, approach it will make to planet Earth in 2029. CNN Sans & 2016 Cable News Network. Measuring at over 1,100 feet across, Apophis is expected to pass within just 19,000 miles of the earth surface, once again below the orbit of weather satellites. On Dec. 27, researchers at the High-frequency Active Auroral Research Program (HAARP) in Gakona, Alaska, sent a low-frequency radio signal to an asteroid called 2010 XC15. At its farthest, Apophis can reach a distance of about 2 astronomical units (One astronomical unit, abbreviated as AU, is the distance from the Sun to Earth.) Its path has been plotted and studied in great detail and its clear at this point that theres no chance of it hitting Earth at least in 2029. Original estimates had thought the asteroid was 450 meters in diameter. But whats the difference between them? We will be able to see it (from the Eastern Hemisphere) without the aid of a telescope or binoculars. By AARON It was part of a test to see if radio waves could penetrate an asteroid and send back data on its interior structure, said Mark Haynes, the JPL radar systems engineer who led the project. As suitably apocalyptic as that sounds, though, that may not be the main inspiration behind the name. Apophis might just give us that chance. In addition to flagging some key priorities for the next decade, scientists also discussed some top-level mission concepts that could lay the groundwork for spacecraft to visit Apophis before, during or after its close approach. Astronomers Roy A. Tucker, David J. Tholen and Fabrizio Bernardi discovered Apophis on June 19, 2004, while working at the Kitt Peak National Observatory in Arizona, according to NASA.

The tweaks the Yarkovsky effect cause in an asteroid's orbit are so small that scientists struggle to distinguish the nudges from instrument hiccups. But that impact assessment changed after astronomers tracked Apophis and its orbit became better determined. New York, This story originally appeared in Los Angeles Times. https://cneos.jpl.nasa.gov/news/news146.html (opens in new tab). Even so, we were able to acquire incredibly precise information about its distance to an accuracy of about 150 meters [490 feet], said JPL scientist Marina Brozovic, who led the radar campaign. But there were still reasons to fear that an impact could happen, and that surrounds the existence of the gravitational keyhole. "About 100,000 times more than the energy of the Chelyabinsk meteor and a million times more energy than the bombs dropped on Hiroshima." NASA has extended the planetary science missions of eight of its spacecraft due to their scientific productivity and potential to deepen our knowledge. Space is part of Future US Inc, an international media group and leading digital publisher. However, the impact assessment changed as astronomers tracked Apophis using the 70-metre (230-foot) radio antenna at the Deep Space Networks Goldstone Deep Space Communications Complex near Barstow, California.The US space agency NASA confirmed in 2021 that Earth was deemed "safe" from the space traveller for the next 100 years at least.NASA confirmed that on 13 April 2029, the asteroid Apophis will pass less than 20,000 miles (32,000 kilometres) from Earths surface, which is closer than the distance of geosynchronous satellites.NASA added that Apophis, named after the ancient Egyptian god of darkness, chaos and destruction will be visible to observers on the ground in the Eastern Hemisphere without the aid of a telescope or binoculars. In 2029, Apophis will travel 19,400 miles from the surface of the earth, 11 times closer to us than our moon in what is called a close flyby. NASA-funded ATLAS has reached become the first survey capable of searching the entire dark sky every 24 hours for near-Earth objects. On April 13th, 2029, the asteroid known as Apophis will pass by Earth at a distance of just 19,000 miles.

They were only able to observe the asteroid for two days because of technical and weather problems. Retrieved November 16, 2022, from https://cneos.jpl.nasa.gov/sentry/palermo_scale.html (opens in new tab), CNEOS. In a year that seemingly keeps on giving, perhaps its not so surprising that NASAs newly discovered asteroid called 2020 SW will give earth a not so socially distant pass. (n.d.-a). There was a while there when it seemed like it could. The first interplanetary cubesats flew with that spacecraft as the MarCO mission. It originated in the main asteroid belt between Mars and Jupiter. That collision may have cast the fragment we call Apophis on a trajectory that resulted in its current orbit that comes very close to Earth." To compare, the Tunguska event, when a mysterious asteroid exploded above the surface of the Siberian wilderness in 1908, was estimated to have been somewhere between 3-10 megatons of TNT.

One topic of high interest for the week happened on April 30, 2019. However, it will not stay that way, and is set to be reclassified as an Apollo-class asteroid after the anticipated close flyby due to its orbit now becoming wider. Theres never a fee to submit your organizations information for consideration. Observations of Apophis in 2029 also should give scientists a better idea of the asteroid's size, shape and composition, and even allow them to model the space rock's interior for the first time. Essentially, this is a small region of space influenced by a planet's gravity. ET on April 13, 2029, the massive asteroid will cross over the Atlantic Ocean and the United States in a little 2021 PDC is observed extensively during the week after discovery, and as the observational dataset grows from one day to the next, the impact Larger asteroids pose an obvious threat in the even of an impact, and can be detected much farther away from Earth, as their rate of motion in the sky is often much smaller at that distance. The CNEOS team also ruled out a potential impact for the next 100 years, Farnocchia said. Related: Huge Asteroid Apophis Revealed in Photos. "If Apophis passed through specific gravitational keyholes, the gravity of the Earth would tweak its orbit by just the right amount or should I say the wrong amount to put it on a collision course in a later year," Farnocchia told Space.com via email.
