Hitekno.com – For astronomer submit a plan for fishing meteorite who fell into the sea using rocks magnet. What are the details of this plan?

Gazetted Suara.comThis meteorite came from another star system that crashed into the Pacific Ocean with an energy equivalent to about 121 tons of TNT.

Known as CNEOS 2014-01-08a team of astronomers from Harvard University hopes to find fragments of the interstellar rock that hit Earth on January 8, 2014.

Finding such a fragment would be humanity’s first contact with material larger than the outer solar system’s dust,” said Amir Siraj, an astrophysicist at Harvard University, quoted from Live Science, Monday (15/8/2022).

Siraj identified the object’s origin in the 2019 study with 99.999 percent confidence, but it wasn’t until May 2022 that it was confirmed to Siraj by the United States Space Command.

There are no known witnesses to the object that hit Earth.

It hit the atmosphere about 160 kilometers off the coast of Papua New Guinea at midnight, with a force equivalent to about 1 percent of the energy of the Hiroshima bomb.” added Siraj.

CNEOS 2014-01-08 measures 0.5 meters and appears to be the first interstellar object ever discovered in the solar system.

CNEOS 2014-01-08 is thought to be from another star system because it is moving at a speed of 60 kilometers per second relative to the Sun.

The object is too fast to be bound by the Sun’s gravity.

In the latest mission, Siraj and his colleagues will undertake a $1.6 million expedition to lower a magnet to the location where the meteorite fell.

According to Siraj, CNEOS 2014-01-08 far exceeds the strength of ordinary iron meteorite materials, which should make it easier to recover.

The strength of a material itself refers to how easily something can withstand deformation or damage by loads.

According to Siraj, most meteorites contain enough iron that it will stick to the kind of magnets we would use on sea expeditions.

Given the very high strength of the material, it is most likely that the CNEOS 2014-01-08 fragment is ferromagnetic,” closed Siraj.

The project, called Galileo, will use ships with the help of magnetic sleds.

It will be towed along the seabed at a depth of 1.7 km for 10 days.

It is hoped that the magnets can recover tiny fragments of the 0.004-inch meteorite.

However, it is not yet clear when astronomers will be able to carry out the expedition, given the funds needed.

That’s the plan of astronomers who want to lure meteorites that fall into the sea with magnetic rocks. (Suara.com/ Lintang Siltya Utami).
