Zur Startseite. Die Ausrichtung der Achse ist noch nicht genau bekannt, aber für die Richtung des Jarkowski-Effekts wichtig. April sehr nahe kommen wird. Bitte auch den Hinweis zu Asteroidenartikeln beachten.
Verschwörungstheoretiker aufgepasst! Doch keine Panik. Als Asteroiden bezeichnen Weltraumexperten astronomische Kleinkörper mit einem Durchmesser ab einem Remmo Clan, die die Sonne umrunden. Forscher hoffen, dass in Zukunft künstliche Intelligenz beim Identifizieren möglicher gefährlicher Asteroiden helfen kann. Auch interessant. The extra data ruled out a collision in On April 13, , asteroid MN4 will fly past Earth only 18, miles 30, km above the ground.
For comparison, geosynchronous satellites orbit at 22, miles 36, km. This is rare. Uncertainty in the asteroid's close-approach distance is represented by the short white bar.
The asteroid's trajectory will bend approximately 28 degrees during the encounter, "a result of Earth's gravitational pull," explains Giorgini.
What happens next is uncertain. Some newspapers have stated that the asteroid might swing around and hit Earth after all in or so, but Giorgini discounts that: "Our ability to 'see' where MN4 will go by extrapolating its orbit is so blurred out by the Earth encounter, it can't even be said for certain what side of the sun MN4 will be on in Talk of Earth encounters in is premature.
Coincidentally, the Arecibo dish is about the same size as the asteroid. More data are needed to forecast MN4's motion beyond The asteroid will be about 9 million miles 14 million km from Earth, invisible to the naked eye, but close enough for radar studies.
The closest encounter of all, Friday the 13th, , will be a spectacular opportunity to explore this asteroid via radar. During this encounter, says Giorgini, "radar could detect the distortion of MN4's shape and spin as it passes through Earth's gravity field.
How the asteroid changes or not would provide information about its internal structure and material composition. The view through an optical telescope won't be so impressive.
The asteroid's maximum angular diameter is only 2 to 4 arcseconds, which means it will be a starlike point of light in all but the very largest telescopes.
But to the naked eye--wow! No one in recorded history has ever seen an asteroid in space so bright. May 13, Friday the 13th, Asteroid MN4 will come scarily close to Earth on April 13, , but it will not hit.

Sq [6]. The original NASA report mentioned impact chances of "around 1 in " in , which was widely reported in the media. Later that day, based on a total of 64 observations, the estimates were changed to 1 in 62 1.
The chances were first reported as 1 in 42 2. Based on a total of observations, the impact probability was still estimated as 1 in 45 2.
Based on a total of observations with an observation arc of days, the impact probability was raised to 1 in 37 2. Later that afternoon, a precovery increased the span of observations to days, which eliminated the impact threat.
A approach to Earth still poses a minor risk of impact, and Apophis was still rated at level one on the Torino scale for this orbit.
Based on a total of observations, a value of one was given on the Torino scale for The only pass rated 1 on the Torino scale was for This was still the case based upon observations spanning The most dangerous pass was rated at 1 in 7,, One pass at 1 Torino scale 3 other passes.
Observations spanning Extremely precise radar observations at Arecibo Observatory [20] refine the orbit further and show that the April close approach will occur at only 5.
Apophis MN 4 had a 1-in, chance of impacting in April Radar observation [20] refines the orbit further and eliminates the possibility of an impact in Nico Marquardt published a research paper in which he calculated the probability of Apophis to collide with a geosynchronous satellite during its flyby on April 13, , and the consequences of this event to the likelihood of an Earth-collision Afterwards, the German newspaper Bild published an article stating a times higher probability of an Earth-collision in the year than Marquardt calculated.
The release went on to explain that since the angle of Apophis's approach to the Earth's equator means the asteroid will not travel through the belt of current equatorial geosynchronous satellites, there is currently no risk of collision; and the effect on Apophis's orbit of any such impact would be insignificant.
NASA News Release reaffirmed that its estimation of a 1-in, chance of impact in remained valid. An animation is released [56] that shows how unmeasured physical parameters of Apophis bias the entire statistical uncertainty region.
If Apophis is a retrograde rotator on the small, less-massive end of what is possible, the measurement uncertainty region will get pushed back such that the center of the distribution encounters Earth's orbit.
This would result in an impact probability much higher than computed with the Standard Dynamical Model.
Conversely, if Apophis is a small, less-massive prograde rotator, the uncertainty region is advanced along the orbit. Only the remote tails of the probability distribution could encounter Earth, producing a negligible impact probability.
Refinements to the precovery images of Apophis by the University of Hawaii's Institute for Astronomy , the inch Bok Telescope , and the Arecibo Observatory have generated a refined path that reduces the odds of an April 13, , impact to about 1 in , Criticism of older published impact probabilities rests on the fact that important physical parameters such as mass and spin that affect its precise trajectory have not yet been accurately measured and hence there are no associated probability distributions.
The Standard Dynamical Model used for making predictions simplifies calculations by assuming Earth is a point mass; this can introduce up to 2.
A statistical impact risk analysis of the data up to this point calculated that the odds of the impact at 7. The same study looked at the odds of an impact in , which were calculated at 2.
The initial data shows the asteroid to be bigger than first estimated because it is now expected to be less reflective than originally thought.

Recommended Articles. July 10, April 10, Finding the Invisible. March 10, Citizen Scientists Discover Dozens of August 18, Additional observations provided improved predictions that eliminated the possibility of an impact on Earth or the Moon in Apophis was discovered on June 19, , by Roy A.
Tucker , David J. See diagram below:. When first discovered, the object received the provisional designation MN 4 , and early news and scientific articles naturally referred to it by that name.
He is the Uncreator, an evil serpent that dwells in the eternal darkness of the Duat and tries to swallow Ra during his nightly passage.
Apep is held at bay by Set , the Ancient Egyptian god of storms and the desert. Tholen and Tucker, two of the co-discoverers of the asteroid, are reportedly fans of the television series Stargate SG One of the show's persistent villains is an alien named Apophis.
He is one of the principal threats to the existence of civilization on Earth through the first few seasons, thus likely why the asteroid was named after him.
In the fictional world of the show, the alien's backstory was that he had lived on Earth during ancient times and had posed as a god, thereby giving rise to the myth of the Egyptian god of the same name.
Due to the closeness of the approach, it is likely that tidal forces will alter Apophis's rotation axis. A partial resurfacing of the asteroid is possible, which might change its spectral class from a weathered Sq- to an unweathered Q-type.
The distance, a hair's breadth in astronomical terms, is five times the radius of the Earth , ten times closer than the Moon , and even closer than some man-made satellites.
During the approach, Earth will perturb Apophis from an Aten -class orbit with a semi-major axis of 0. Close approach of Apophis on April 13, , as known in February [21].
The white bar indicates uncertainty in the range of positions as known in February [21]. Six months after discovery, and shortly after a close approach to Earth on December 21, , the improved orbital estimates led to the prediction of a very close approach on April 13, , by both NASA's automatic Sentry system and NEODyS , a similar automatic program run by the University of Pisa and the University of Valladolid.
Subsequent observations decreased the uncertainty in Apophis's trajectory. The probability of an impact event in temporarily climbed, peaking at 2.
These are the highest values for which any object has been rated on either scale. The chance that there would be an impact in was eliminated by late December 27, , as a result of a precovery image that extended the observation arc back to March In July , former Apollo astronaut Rusty Schweickart , as chairman of the B Foundation , formally asked NASA to investigate the possibility that the asteroid's post orbit could be in orbital resonance with Earth, which would increase the probability of future impacts.
Schweickart also asked NASA to investigate whether a transponder should be placed on the asteroid to enable more accurate tracking of how its orbit is affected by the Yarkovsky effect.
The close approach in will substantially alter the object's orbit, prompting Jon Giorgini of JPL to say in "If we get radar ranging in [the next good opportunity], we should be able to predict the location of MN 4 out to at least A NASA assessment as of February 21, , that did not use the January and February radar measurements gave an impact probability of 2.
As of January , Apophis has not been observed since , mostly because its orbit has kept it very near the Sun from the perspective of Earth.
It has never been further than 60 degrees from the Sun since April , and will remain so until December With the most recent observations, the April 12, , impact probability is now 6.
In comparison, the Chicxulub impact has been estimated to have released about as much energy as ,, megatons teratons. The exact effects of any impact would vary based on the asteroid's composition, and the location and angle of impact.
Any impact would be extremely detrimental to an area of thousands of square kilometres, but would be unlikely to have long-lasting global effects, such as the initiation of an impact winter.
In , the B Foundation made estimates of Apophis's path if a Earth impact were to occur, as part of an effort to develop viable deflection strategies.
The commercial competition was won by a design called 'Foresight' created by SpaceWorks Enterprises, Inc. It would then rendezvous with, observe, and track the asteroid.
Foresight would orbit the asteroid to gather data with a multi-spectral imager for one month. It would then leave orbit and fly in formation with Apophis around the Sun at a range of two kilometres 1.
The spacecraft would use laser ranging to the asteroid and radio tracking from Earth for ten months to accurately determine the asteroid's orbit and how it might change.
Pharos, the winning student entry, would be an orbiter with four science instruments a multi-spectral imager, near-infrared spectrometer , laser rangefinder , and magnetometer that would rendezvous with and track Apophis.
Earth-based tracking of the spacecraft would then allow precise tracking of the asteroid. The Pharos spacecraft would also carry four instrumented probes that it would launch individually over the course of two weeks.
Accelerometers and temperature sensors on the probes would measure the seismic effects of successive probe impacts, a creative way to explore the interior structure and dynamics of the asteroid.
Juan L. Cano was principal investigator. The principal investigator was Paolo D'Arrigo. China plans an exploration fly-by mission to Apophis in , several years prior to the close approach in This fly-by mission to Apophis is part of an asteroid exploration mission planned after China's Mars mission in currently in development, according to Ji Jianghui, a researcher at the Purple Mountain Observatory of the Chinese Academy of Sciences and a member of the expert committee for scientific goal argumentation of deep space exploration in China.
The whole mission will include exploration and close study of three asteroids by sending a probe to fly side by side with Apophis for a period to conduct close observation, and land on the asteroid FG3 to conduct in situ sampling analysis on the surface.
The probe is also expected to conduct a fly-by of a third asteroid to be determined at a later time. The whole mission would last around six years, said Ji.
Apophis is one of two asteroids that were considered by the European Space Agency as the target of its Don Quijote mission concept to study the effects of impacting an asteroid.
Studies by NASA, ESA, [70] and various research groups in addition to the Planetary Society contest teams, [71] have described a number of proposals for deflecting Apophis or similar objects, including gravitational tractor , kinetic impact , and nuclear bomb methods.
On December 30, , Anatoly Perminov , the director of the Russian Federal Space Agency, said in an interview that Roscosmos will also study designs for a possible deflection mission to Apophis.
On August 16, , researchers at China's Tsinghua University proposed launching a mission to knock Apophis onto a safer course using an impactor spacecraft in a retrograde orbit, steered and powered by a solar sail.
Instead of moving the asteroid on its potential resonant return to Earth, Shengping Gong and his team believe the secret is shifting the asteroid away from entering the gravitational keyhole in the first place.
Although the report stated that likely targets would be between the 20 to 50 metres in size, it was also stated that Apophis would be an object subject to tests by the program.
