The meteorite measures about 200 kilometers in diameter Psychiatry It is one of the most significant in the solar system. Stellar object, which is 370 million kilometers away from our planet and orbits in between Tuesday and ThursdayIt is worth about $ 10 trillion, which represents 300 times the global economy.
A new study of the celestial body established that it might be Contains only iron and nickel. The team of scientists studied the millimeter wavelength emissions of the asteroid, creating the first temperature map of the object and opening a new perspective on its surface properties.
The article was published in the journal Science Journal of Planetary Science, Confirmed what had already been speculated about the asteroid: that Worth more than the entire economy of the earth.
At least 30% of the surface of the psyche is made of metal
The mind is coming around Word In the asteroid belt, a disk The Solar System It is located between the orbits of Mars and Jupiter, and contains more than a million rock bodies ranging in diameter from 10 meters to nearly 1000 kilometers.
Psychiatry was discovered on March 17, 1852 Hannibal of Casparis From the lab Capodimonde in Naples, Italy. Its name comes from the deity of Greco-Roman mythology who expressed the soul. With a diameter of more than 200 km, it is the largest of the M-type asteroids, believed to be rich in metals, and may be fragments of the nuclei of decomposed protoplanets during the formation of the solar system.
The authors of the new study said The heat dissipation of the psyche is high Compared to a conventional asteroid, this fact indicates that the celestial body has an unusually dense or conductive surface.
This situation makes sense for it At least 30% of the surface of the psyche is made of metal. In addition, the researchers found that the light emitted by the asteroid was scattered, suggesting that the rocks on the surface were filled with metal grains.
“We have known for many years that the materials of this class are not solid metals, but what they are and how they are formed remains a mystery,” he said. Katherine de Clear, Associate Professor California Institute of Technology Planetarium of Science and Astronomy And co-author of the study.
Based on this finding, scientists will seek to apply the techniques described in the article to other large objects in the asteroid belt, which provide a new perspective on the surface compounds of these celestial bodies.
According to researchers, the value of all the metals that make up this asteroid exceeds the value of the world economy. Lindy Elkins-Tandon, One of the foremost researchers in the field of psychology NASA, Calculated to be only the iron of the celestial body Its value is about $ 10 trillion. In comparison, the press specializes in the world of finance, Forbes, Valued the world economy at $ 142 trillion in 2019.
