Will Asteroid Apophis Hit Earth

Will asteroid Apophis hit the Earth in 2029 or 2036?

“Astronomers estimate that on April 13, 2029, Apophis will pass by the Earth at a distance of no closer than 18,300 miles (29,470 kilometers). The next close approach of this asteroid is expected in April 2036, when it will miss Earth at a much larger distance of approximately 30.5 million miles (49 million kilometers).However, Alberto Cellino of the Observatory of Turin in Italy told Astronomy and Space News - Astro Watch in June that although the potential impact in 2029 was excluded, we cannot rule out such an event in the more distant future. Given the fact that NEO orbits are chaotic, what is not dangerous today can become a candidate impactor in the future…”Read more at: https://phys.org/news/2017-08-as...

Will Asteroid 99942 Apophis hit Earth in 2029 or 2036?

Will Asteroid 99942 Apophis hit Earth in 2029 or 2036?No, Apophis will miss in 2029 and 2036. Radar observations made during the close encounter the week of Jan 10, 2013 ruled out any collision. Scientists use the phrase “significant digits” when discussing data and they’ve got enough to make accurate predictions about Apophis. There are random, small changes to any asteroid’s orbit because of the Yarkovsky effect and possible but unlikely collisions with small, undetected asteroids. The Wikipedia article about 99942 Apophis tells us that the present orbit predictions, using observations through February 26, 2014, provide odds of 1 in 150,000 of an impact on April 12, 2068, as calculated by the JPL Sentry risk table. When each of the close flyby between now and then happen, additional tracking will once again allow for the asteroid’s orbital data to be updated and for precise predictions to be made.

Will Apophis hit Earth in 2068?

99942 Apophis (/əˈpɒfɪs/, previously known by its provisional designation 2004 MN4) is a near-Earth asteroid that caused a brief period of concern in December 2004 because initial observations indicated a probability of up to 2.7% that it would hit Earth on April 13, 2029. Additional observations provided improved predictions that eliminated the possibility of an impact on Earth or the Moon in 2029. However, until 2006, a possibility remained that during the 2029 close encounter with Earth, Apophis would pass through a gravitational keyhole, a small region no more than about 0.5 mile wide, or 0.8 km that would set up a future impact exactly seven years later on April 13, 2036. This possibility kept it at Level 1 on the Torino impact hazard scale until August 2006, when the probability that Apophis would pass through the keyhole was determined to be very small. By 2008, the keyhole had been determined to be less than 1 km wideSo no. Apophis will NOT impact Earth in 2029 or 2036 or even 2068.

If the asteroid Apophis will indeed strike the Earth in 2036, is there something we could do to prevent it? What are the odds of something fatal happening?

Your facts aren't entirely true.It’s expected to come close in 2029 and in 2036 but its chances of hitting Earth stand at less than 3%. It may take down a few satellites though.Anyhow, if we prove to be extremely unlucky, and it's doomed to hit us, then we will get to know about it atleast a month before the impact.And I guess our only chance would be to bamboozle it with multiple missiles simultaneously, in hopes of shattering it into smaller, less dangerous fragments.
