Asteroid Ryugu had distant beginnings<\/h2>\n\n
\"\"
Surface samples show Ryugu formed in the outer Solar System, possibly even beyond Jupiter <\/figcaption><\/figure><\/div>\n\n

The first analysis <\/strong>of samples brought back to Earth from the asteroid Ryugu have now been completed, showing the space rock probably began its life much further out in the cold, dark reaches of the Solar System. <\/p>\n\n

In 2019, the Japanese spacecraft Hayabusa2 took surface samples from Ryugu, returning them to Earth in 2020 to be examined by eager researchers around the world. These preliminary tests found the dust contained water laced with carbon dioxide. This could only happen if both substances were solid when the asteroid body formed, meaning its original orbit was three to four times the Earth\u2013Sun distance; that\u2019s twice as far out as it is now. <\/p>\n\n

\u201cThe mineralogy of the Ryugu samples is similar to CI chondrites, a carbon-rich meteorite collected here on Earth,\u201d says Deborah Domingue, from the Planetary Science Institute, who took part in the study. Meteorites are our most easily accessible samples of asteroid material here on Earth, but their source is often unknown. \u201cUnderstanding the formation history of Ryugu has real implications for understanding the origin of these meteorites and where their parent bodies formed in our Solar System.\u201d <\/span>www.psi.edu\/news\/analysisruygusamples<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
