Iwastheone shares a report from Observer: NASA’s Hubble Space Telescope has discovered a rare, heavy and immensely valuable asteroid called “16 Psyche” in the Solar System’s main asteroid belt between Mars and Jupiter. Asteroid Psyche is located at roughly 230 million miles (370 million kilometers) from Earth and measures 140 miles (226 kilometers) across, about the size of West Virginia. What makes it special is that, unlike most asteroids that are either rocky or icy, Psyche is made almost entirely of metals, just like the core of Earth, according to a study published in the Planetary Science Journal on Monday.
Given the asteroid’s size, its metal content could be worth $10,000 quadrillion ($10,000,000,000,000,000,000), or about 10,000 times the global economy as of 2019. Using ultraviolet spectrum data collected by the Space Telescope Imaging Spectrograph on the Hubble Space Telescope during two observations in 2017, researchers deduced that Psyche’s surface could be mostly pure iron. However, they recognized that the presence of an iron composition of as small as 10 percent could dominate ultraviolet observations. Psyche is the target of the NASA Discovery Mission Psyche, expected to launch in 2022 atop a SpaceX Falcon Heavy rocket. Further facts about the asteroid, including its exact metal content, will hopefully be uncovered when an orbiting probe arrives in early 2026. The asteroid is believed to be the dead core left by a planet that failed during its formation early in the Solar System’s life or the result of many violent collisions in its distant past.
