Scientists believe that the asteroid 16 Psyche is the core of a protoplanet that was shattered a few billion years ago. With a composition of 90 percent metal and 10 percent silicate rock, it is believed to be much denser than a rocky object of similar size, which contains approximately 1 percent of the total mass of the asteroid belt. According to the US space agency NASA, the asteroid was named after the nymph Psyche, who Cupid married but was killed by Venus. At Cupid’s request, however, Jupiter made Psyche immortal.
The main target of the Psyche mission, the Psyche spaceship, will launch in August 2022 and arrive at the asteroid in 2026 after a Mars gravity support in 2023.
According to a report in Extreme TechAssuming the asteroid’s core is made up of iron and nickel, the total value of the asteroid is $ 10,000 trillion.

The Hubble Space Telescope has now spent some time examining the planet’s body. Researchers have examined the psyche in the ultraviolet range and found that it has a high iron composition. However, they found that a relatively small amount of iron was mixed into rocky materials such as olivine.
Scientists have a number of theories about how Psyche might have formed, but the UV analyzes do not confirm whether Psyche is an iron-rich nuclear residue. The asteroid is the only known metal core-like body from a planet currently floating around.
According to researchers, one of the reasons the asteroid belt has not been able to reunite into one planet is this Jupiter held up the gravitational energies to support planetary accretion. And so the material in the belt was either thrown out, beaten, flung inward, or swallowed by Jupiter himself.
The goal of NASA’s mission to study 16 Psyche is to determine whether the space rock represents a planetary core or a mass of previously unmelted material. An attempt is also made to identify the differences in the composition between the minerals in the core of the psyche and the expected contents of the earth and the conditions under which it was formed.
The results of the study were published in Das Planetary Science Journal.
