Heureusement, au cours des derniers jours du mois de décembre 2004, une photographie prise quelques mois avant le mois de juin et montrant déjà 2004 MN4 avait été retrouvée dans les archives, conduisant à une évaluation plus précise de la trajectoire de l'astéroïde pour 2029. It has never been further than 60 degrees from the Sun since April 2014, and will remain so until December 2019. Les chercheurs ont bien eu quelques inquiétudes pour … ), sans pour autant avoir des conséquences majeures sur les populations humaines.
With the most recent 2015 observations, the April 12, 2068, impact probability is now 6.7 in a million (1 in 150,000), and the asteroid has a cumulative 9-in-a-million (1-in-110,000) chance of impacting Earth before 2106.The Sentry Risk Table estimates that Apophis would impact Earth with The exact effects of any impact would vary based on the asteroid's composition, and the location and angle of impact. Named for the Egyptian god of chaos, near-Earth asteroid 99942 Apophis will get super-close to Earth on April 13, 2029, grazing our geostationary satellites (see image below). Apophis is an asteroid the size of four football fields hurtling through space at --,---(--,---, --) .In 2004 it reached the highest ever impact hazard category 4 on the Torino scale with the odds of a collision with Earth estimated at 2.7%, according to NASA.
Un impact maritime pourrait provoquer d'importants dommages (tsunami etc. Their team lead was Two teams tied for second place in the Student Category: China plans an exploration fly-by mission to Apophis in 2022, several years prior to the close approach in 2029. 99942 Apophis was previously designated 2004 MN4. As of 2014, the diameter of Apophis is estimated to be approximately 370 metres (1,210 ft).When first discovered, the object received the provisional designation Tholen and Tucker, two of the co-discoverers of the asteroid, are reportedly fans of the television series The mythological creature Apophis is pronounced with the accent on the first syllable (/ˈæpəfɪs/). (99942) Apophis (anciennement 2004 MN4) est un astéroïde géocroiseur de type sidérite, qui fut découvert le 19 juin 2004. The distance, a hair's breadth in astronomical terms, is five times the On April 13, 2029, Apophis will pass Earth closer than Close approach of Apophis on April 13, 2029, (as known in February 2005)The white bar indicates uncertainty in the range of positions (as known in February 2005)Six months after discovery, and shortly after a close approach to Earth on December 21, 2004, the improved orbital estimates led to the prediction of a very close approach on April 13, 2029, by both NASA's automatic The close approach in 2029 will substantially alter the object's orbit, prompting Jon Giorgini of JPL to say in 2011: "If we get radar ranging in 2013 [the next good opportunity], we should be able to predict the location of A NASA assessment as of February 21, 2013, that did not use the January and February 2013 radar measurements gave an impact probability of 2.3 in a million for 2068.As of January 2019, Apophis has not been observed since 2015, mostly because its orbit has kept it very near the Sun from the perspective of Earth. En tout état de cause, l'astéroïde mesurant moins d'un kilomètre de diamètre, son impact n'aurait eu que des conséquences « régionales »La chute d'Apophis sur Terre, à la suite de plusieurs Trajectoires de (99942) Apophis et de la Terre ; estimation au 13 avril 2029. Additional observations provided improved predictions that eliminated the possibility of an impact on Earth or the Moon in 2029. Il était déjà devenu clair, en 2004, qu'un impact était en fait très improbable en 2029.
Asteroid 99942 Apophis is currently in the constellation of Virgo.The current Right Ascension of Asteroid 99942 Apophis is 13h 14m 29s and the Declination is -01° 58’ 19” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom []).The current magnitude of Asteroid 99942 Apophis is 21.41 (JPL). Based upon the observed brightness, Apophis's diameter was initially estimated at 450 metres (1,480 ft); a more refined estimate based on spectroscopic observations at Based on Goldstone and Arecibo radar images taken in 2012–2013, During the 2029 approach, Apophis's brightness will peak at The closest known approach of Apophis comes on April 13, 2029, when the asteroid comes to within a distance of around 31,000 kilometres from Earth's surface.
