r/AsteroidApophis. This is a sub dedicated to Asteroid Apophis. I became aware of this situation in 2013, since then information has been pretty slim as far as more and more details coming to surface. However, as we approach 2029 and 2036, attention to this subject is going to increase. This place is a safe space for discussion on the scenarios ...
The article sucks so I found the press conference where this was announced, and here is the link to where the discussion of this starts. To recap, previously the risk of the asteroid hitting us in 2068 was 1/150,000. What is crucial is a flyby in 2029 where the asteroid will also come really close to Earth, passing through a gravitational ...
According to this NASA paper (pdf), Apophis will pass within 38x10 6 m of us in 2029 at a relative velocity of 7422 m/s . At that distance, the escape velocity is 4581 m/s , so all you would have to do is get rid of that 2841 m/s and Apophis would be captured (in an infinitely elliptical orbit). Circular orbit at that distance is 3239 m/s so ...
ADMIN MOD. 5 years left until the Apophis flyby. On April 13, 2029, the 370 meter wide asteroid Apophis will pass less than 20,000 miles (32,000 km) from Earth. While it poses no danger to Earth, it’ll reach an apparent magnitude of 3.1, which will make it visible to the unaided eye. At ~2.4 arcseconds at its closest approach, it will be too ...
The Apophis asteroid was discovered in 2004 and has been monitored since then due to its classification as a potentially hazardous asteroid (PHA), as it was estimated that it would have a 2% chance of hitting Earth.
The estimate on the Palermo Technical Impact Hazard Scale suggests there’s a 1 in 150,000 chance of Apophis hitting Earth on April 12, 2068. An impact with the surface would release the equivalent of 1,151 megatons of TNT. Such a calamitous event happens on Earth around once every 80,000 years.
On the night of March 5, 2021, the huge space rock will pass at 10,471,577 miles (16,852,369 km) from our planet, i.e. about 44 times the distance to the moon. Apophis is then expected to reach a visual magnitude of 15 to 16, too faint to be seen in small telescopes, but within the reach of 12-inch-diameter and larger telescopes, and possibly ...
The moon is 1000000000000 times more massive than Apophis, and so will exert 1000000000000 times more gravitational disturbance on the asteroid than the asteroid can exert on the moon. The effect on the moon’s orbit will be negligible, but the effect on the asteroid’s orbit may be significant.
Asteroid Apophis in 13,04,2029 will bring the biblical flood and will transform the Earth's magnetic field which will cause a biblical flood. 3500 years ago he changed the magnetic poles caused a tsunami of 300 meters all over the world.
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.[citation needed] Assuming Apophis is a 370-metre-wide (1,210 ft) stony asteroid with a density of 3,000 kg/m3, if it were to impact into sedimentary rock ...
