Jakarta, CNBC Indonesia – An asteroid named Ryugu is thought to have ties to human life on Earth. According to the researchers, such asteroids account for 6% of the Earth’s mass.
Ryugu himself came under investigation two years ago after his sample was brought in by Japan’s Hayabusa-2 spacecraft. Analysts of these samples reveal new information about the past of the Earth and the entire solar system.
The scientific team was led by Dr. Marine Paquet and Dr. Frederic Moynier of the Institut de Physique du Globe de Paris. They were particularly interested in the isotopic signatures of zinc and copper.
IFL Science Explaining isotope ratios can tell the current composition of asteroids. It also tells about the formation of these space objects.
The team determined that the Ryugu isotope and copper traces were the same as the Ivuna meteorite. The meteorite fell in Tanzania on December 16, 1938 and belongs to the CI group of Carbon Chondrites.
There are only nine that enter it and it is one of the rarest. It is also believed that this group formed in the outer solar system and migrated inward.
Ryugu shows the same composition as the other group members. Ultimately the research team tried to select zinc and copper elements to confirm the relationship with CI chondrites, cited on Wednesday (12/14/2022).
Ryugu’s material is thought to be pure enough to determine the composition of the early solar system. Meteorites that form closer to the Sun have a different value from Ryugu.
Therefore, the researchers believe that a Ryugu-like asteroid accounts for 6% of the Earth’s mass.
