Asteroid sang dewa kehancuran diprediksi akan menghantam bumi?
An asteroid named after the God of Chaos Earth, an asteroid as big as the pyramids of Ancient Egypt, is predicted to be on its way to approaching Earth. Researchers reveal that there is a slight possibility of an asteroid collision scenario with Earth in 2050.
The observations made earlier this year used the Subaru Telescope in Hawaii. The telescope is giving astronomers a better picture of how the Yarkovsky effect affects the orbital path of the asteroid 99992 Apophis.,
A report from the University of Hawaii's Institute of Astronomy shows that the asteroid Apophis 1,000 feet wide or about 345 meters is predicted to be very close to Earth by 2060,
This effect is like the built-in propulsion system for this asteroid, where the trace amount of radiation that has leaked out can change the momentum of objects in space. This can cause the object to deviate slightly from the path chosen by gravity.
"Regardless of Yarkovsky's shift, Apophis is still a threatening object, just not in 2060. Taking Yarkovsky into account, the 2068 impact scenario is still ongoing. Small, but not zero," said astronomer and co-author of the report Dave Tholen.
Apophis currently holds the title of third highest threat in the N4S4 Safeguard Risk Table. Estimates on the Palermo's Technical Impact Danger Scale suggest there is a 1 in 170,000 chance of Apophis hitting Earth on April 12, 2068. That scale is proportional to the percentage of 0.00099.,
Tolen said the real odds were closer to 1 in 550,000, a figure used by impact monitoring service NEODyS, which includes Yarkovsky's nominal deviation rate.
If there was a collision between Apophis and Earth it was very bad. Apophis is nickel and lumpy iron and is the size of more than three football fields. Or stadium,
A collision with the surface would release the equivalent of 1,151 megatons of TNT. Such catastrophic events occur on Earth about once every 80,000 years.
The new analysis will generate revised threat risks for Apophis. However, Tholen said this calculation must be studied carefully because there will be other variables to consider.
Tholen said the probability of an asteroid hitting Earth is constantly changing along with a better understanding of the asteroid's travel path.
Astronomers had previously rejected the possibility that an asteroid would hit Earth. In fact the Yarkovsky effect changes the statement that there is no chance an asteroid will hit our beloved Earth,
Reporting from Gizmodo, the asteroid's orbit has shifted due to the Yarkovsky effect. This acceleration occurs because the asteroids absorb sunlight as they fall in the solar system.
Citing Complex, to maintain thermal balance, the asteroid will emit solar energy as heat. This produces a force that causes velocity and will change the orbit of the asteroid.
"EXPLANATION ABOUT ASTEROID"
The discoveries of modern astronomy have succeeded in revealing that the iron metal on Earth actually comes from extraterrestrial bodies. These modern findings reveal that the heavy metals in the universe are made and produced in the cores of giant stars.
In the book 'Koran vs Modern Science according to Dr Zakir Naik' by Ramadhani et al, it is stated that iron is not produced from the solar system. Iron can only be produced from stars larger than the sun whose temperatures reach hundreds of millions of degrees.
Long before humans knew about this natural phenomenon, the Koran has revealed this fact.
Indeed, We have sent Our messengers with clear evidence and We have brought down with them the Bible and balance (justice) so that humans can carry out justice. And We created iron in which there is great strength and various benefits for humans, (so that they can use the iron) and so that Allah will know who is helping Him (religion) and His messenger,
even though Allah does not see Him. Verily Allah is Strong, Mighty, "Surah Al Hadid Verse 25.
In that verse the word 'anzalnaa' in Arabic means 'we send it down'. The use of this word for iron can be interpreted as 'we created' which means to be derived and is considered a figurative word to explain the benefits of iron for humans
