What is the meaning of the name apophis?
(mythology) The Greek name for the Egyptian mythological figure. The Egyptian name is w:Apep, Apep.(astronomy) A near-earth asteroid designated with the permanent number 99942. There is a Wikipedia article on W:99942 Apophis, 99942 Apophis.
What is the name of the asteroid that will be near earth in 2029?
99942 Apophis is an asteroid where initial observations indicated a small probability (up to 2.7%) that it would strike the Earth in 2029.Later observations concluded that the asteroid would miss the Earth.The chances are now set at a one in 3 million that it will hit Earth.
How big of crater would 99942 apophis asteroid make?
About the size of three football fields.
How big is apophis 99942 the meteor?
525 feet
Is 99942 Apophis a comet or meteor?
Neither; Apophis is an asteroid, and not especially large. It would bear no mention at all, except for the fact that on Friday, April 13, 2029 it will come within about 20,000 miles of the Earth, closer than the orbit of geosynchronous satellites. But it will miss.
What will happen in 2029?
99942 Apophis is a 270m diameter near Earth asteroid that was thought to be on a collision course with Earth. It caused a panic in 2004 as it was thought that it might hit the earth in 2029. New calculations estimate that the asteroid will now most likely miss.
When will apophis hit earth?
The asteroid 99942 Apophis was set for a possible future impact on April 13, 2036.However, this data was based on predictions that it would collide with Earth in 2004 and then predictions placed the date as 2029. Further observational data discounted this, and the 2036 date was set.The chances that the asteroid will strike the Earth is put as 1:250,000
What will happen on April 13 2036?
Honestly, no one knows with any degree of certainty. Speculation has it that 99942 Apophis, a Near Earth Asteroid (NEA) will pass relatively close to Earth. When it was first discovered, belief was that Apophis would strike the Earth, however new estimates are that Apophis has a 1:140,000,000 chance of striking the Earth (generally unlikely). On the outside chance that Apophis does strike the Earth, its projected path of impact has been refined so that it would be most likely to drop into the North Pacific or Central Atlantic, with smaller likelihood of a land impact over Kazakhstan, Russia, Nicaragua, Venezuela, or the Senegal/Guinea coast. Impact energy is estimated at 750 megatons (the largest nuclear device ever detonated was approximately 56 megatons, and the Chicxulub event is estimated to have release 100 teraton of energy. A direct land strike would produce a 2.7 km crater (slightly larger than Barringer Crater in Arizona), and likely result in a impact winter that could potentially eliminate much of the life on Earth today. A water impact could result in an impact winter scenario, but would definitely cause massive tsunami waves that would travel the entire globe, creating varying levels of devastation along the Earth's coastlines. All of this speculation, without question, can cause a great deal of fear and panic, however, it is important to remember that the odds of Apophis striking Earth are in the winning the lottery while being struck by lighting and being eaten by a shark range.
Will the Apophis "God of Chaos" asteroid hit the Earth in 2029?
Nothing is 100 percent guaranteed in astronomy, but scientists don’t expect the asteroid 99942-Apophis to come into contact with the Earth (or any other celestial bodies in our solar system, for that matter).A blog post from NASA’s Jet Propulsion Laboratory (JPL) at the California Institute of Technology notes that on Friday, April 13, 2029, 99942-Apophis will “cruise harmlessly by Earth, about 19,000 miles (31,000 kilometers) above the surface.”You read that right: An asteroid will come incredibly close to the Earth on Friday the 13th. If you’re superstitious, that seems like bad news, but astronomers aren’t worried.“That’s within the distance [of] some of our spacecraft that orbit Earth,” the blog notes. “The international asteroid research community couldn't be more excited.”Note that they use the word “excited,” not “terrified.” "The Apophis close approach in 2029 will be an incredible opportunity for science," Marina Brozović, a radar scientist at JPL, said in a statement. "We'll observe the asteroid with both optical and radar telescopes. With radar observations, we might be able to see surface details that are only a few meters in size."Without radar, telescopes, or other tools, Apophis will still be impressive. It will be visible to the naked eye and will look like a star moving across the sky. From our perspective, it will become visible above Australia, then move across the Atlantic Ocean, reaching the U.S. West Coast in the early hours of the evening.Apophis was discovered in June 2004, and later that year, a group of Australian astronomers spotted it a second time and calculated a 2.7 percent chance of a collision with Earth. However, subsequent calculations have ruled out that possibility for the 2029 flyby. What about future flybys? Speaking to Newsweek, astronomer Davide Farnocchia put the chances of a collision after 2060 at “less than 1 in 100,000.” That’s still incredibly close by the standards of astronomy, but it’s not something to worry about.If Apophis did come into contact with Earth, it could cause devastating damage, but at 1,110-feet wide, it’s not large enough to cause a global extinction. Asteroids only pose an existential threat to life on Earth when they’re several miles wide; at those sizes, they could throw up enough dust from the planet’s surface to block out sunlight, preventing plant growth and causing global temperature changes. Scientists believe that the object that contributed to the extinction of dinosaurs was about seven to eight miles wide.Apophis isn’t a threat at all—at least, it won’t be in 2029. If you’ve got clear skies that night, count yourself lucky and watch the show (and don’t worry about taking out extra insurance).
When next is an asteroid predicted to hit earth?
At present (May 2011) no asteroids are predicted to hit the Earth, at least not in the next hundred years, and possibly not even then.------------------ Past possible encounters -------------------------2002 NT7 [See related link]A preliminary orbit suggests that 2002 NT7 is on an impact course with Earth and could strike the planet on 1 February, 2019 - although the uncertainties are large.Astronomers have given the object a rating on the so called Palermo technical scale of threat of 0.06, making NT7 the first object to be given a positive value.From its brightness, astronomers estimate it is about two kilometres wide, large enough to cause continent wide devastation on Earth.This has now been downgraded and was removed from the list of potential objects.99942 Apophis [See related link]This was a likely candidate, and scored the highest ever on the Torino scale.It has now been "downsized"

Wiil the world ever end?
i dont think the world will end in 2012 but i heard a comet will hit earth in 2036. i also heard its benn confirmed.http://www.99942-apophis.com/pics/apophis_impact.jpghttp://www.99942-apophis.com/pics/apophis_impact.jpg
