According to scientists, fragments from a distant asteroid helped reveal more about the early life of our sun.
Scientists used samples from the asteroid “Ryugu” to learn more about how asteroids form around us, in addition to the formation of the Earth.
The team, from the Institute of International Physics in Paris, the University of Paris City and the National Center for Scientific Research, found that the asteroid “Ryugu” is made of “carbon chondrite (CI) similar to the Ivona meteorite” (Ivona), which helps scientists better understand the source of the asteroids.
This carbonaceous chondrite (CI) is one of the oldest meteorites thought to contain components that were early in the formation of the Sun.
However, some of the isotopic signatures – for example: titanium and chromium – are associated with other groups of carbonaceous chondrites, so the details of the relationship between Ryugu and carbonaceous chondrites (CI) are not clear.
Carbonaceous chondrites help illuminate our planet, with scientists believing that Ryugu-like objects from the outer sun make up 6% of Earth’s surface.
The new study marks the latest discovery from Ryugu, 300 million kilometers from Earth.
And in the two years since the Japanese spacecraft Hayabusa2 returned to Earth after a space test, scientists have continued to discover many new things about Ryugu, which help explain the story of our planet when it was even younger. And now.
Scientists have been able to track objects from the most distant regions of the solar system in the past, and find them when they fell to Earth in the form of meteorites.
But the Hayabusa2 mission was the first time scientists had looked at such samples without landing in space and on Earth.
