Apophis will be passing earth this week for the last time until 2029. Have you heard of it? Will asteroid apophis hit earth let’s talk about this in this video asteroid apophis the space rock that some scientists say has a slim chance of reaching earth as expected to approach our planet closely. This week, asteroid apophis named 99 942 will be passing over earth this week. On saturday march, 6th at a distance of 0.11 astronomical units, this is equal to an 11th of the distance between earth and the sun. More precisely, this means that the asteroid would come within 16 million kilometers of our planet nearly 40 times as far away as the moon. In spite of these large numbers, it does mean that apophis is close enough with the use of telescopes space weather said asteroid. Apophis is flying past earth this week at a safe distance of 0.11 astronomical units about 40 times farther than the moon. This is our last chance to study the space rock before it returns for a sensational naked eye, plunge through the geosynchronous satellite built in april 2029. The mammoth space rock is a stunning 370 meters wide almost the same size at the height of the empire state building in new york city, which has 381.0 meters to its tip. If apophis were on its way to earth, it is thought that an asteroid of this scale would be able to wipe out a medium sized country. Calculations suggest that the giant space rock will next come even closer to earth in 2029, when scientists will have an unprecedented glimpse at the asteroid.

However, it is the 2068 apophis flight that the researchers are most worried about. Experts from the university of hawaii have previously estimated that there is one in 530 000 chances that earth will be hit in 2068, but earlier this month researchers said the risk was one in 380 000. to put it in perspective, that’s a 99.99974 probability that the asteroid Will miss earth while there’s a chance in 500 000 that you might get hit by lightning, but while the chances are slim they’re, there dave thalin and his university colleagues used the 8.2 meters subaru telescope in mauna kea hawaii to make the new measurements and their results Suggest that the huge space rock is drifting more than 500 feet about 170 meters every year from its predicted position in its orbit, scientists at the institute have observed what is known as yarkovsky’s acceleration on the surface of the asteroid, which could impact the direction of the Rock in its 2068 flyby, the yarkovsky effect as when an asteroid or celestial body changes its orbit due to a slight heat wave, either by expelling gases from itself or by a gravitational push and shove from celestial bodies, including the sun and earth. In this case, the scientists discovered a small thermal reaction that could slightly alter the direction of apophis. Dr thalin said we have known for some time that an impact with earth is not possible during the 2029 close approach. The new observations we obtained with the subaru telescope earlier this year were good enough to reveal the yarkovsky acceleration of apophis, and they show that the asteroid is drifting away from a purely gravitational orbit by about 170 meters about 500 feet per year, which is enough to Keep the 2068 impact scenario in play.

It was previously thought that there was a small possibility that the asteroid would strike earth in 2036, but this was later ruled out. Don yeomans manager of nasa near earth object program office at jpl said at the time with the new data provided by the magdalena ridge, new mexico institute of mining and technology and the pan starrs university of hawaii optical observatories, along with very recent data provided by the Goldstone, solar system radar, we have effectively ruled out the possibility of an earth impact by apophis in 2036.. The impact odds as they stand now are less than one in a million which makes us comfortable saying we can effectively rule out an earth impact in 2036. Our interest in asteroid apophis will essentially be for its scientific interest for the foreseeable future. However, scientists will have a greater idea of the potential course of the asteroid as earth zooms in 2029, the rock will be on its closest approach to earth. Just before 6 pm. Eastern daylight saving time on april 13, 2029, when the massive rock will be over the atlantic ocean, marina brazovic, a radar scientist at nasa jet propulsion laboratory in pasadena california, said the apophis close approach in 2029 will be an incredible opportunity for science. 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. Apophis was named after the ancient egyptian god of evil, darkness and destruction.

The big rock is bigger than the shard in london, and any impact may have significant consequences. If 27 billion kilograms of asteroid were to strike earth, scientists calculate that it would leave a crater more than a mile wide and 518 meters deep. The effect will be equal to 880 million tons of tnt being detonated 65 000 times as strong as the nuclear bomb dropped on hiroshima. Are you enjoying the video?
