In June 2018, Japan’s Hayabusa2 spacecraft retrieved samples from asteroid Ryugu and successfully returned them to Earth.
The work was focused on spherical mineral grains, called chondrule-like objects and calcium-aluminium-rich inclusions (CAIs).
A key finding from the analysis by the Tohoku University group is that the grains in the Ryugu samples were likely transported in widening circles from the inner regions of the early solar system out to the much more distant region where the original asteroid Ryugu formed.
The Ryugu Contain Samples Of The Oldest Solids In The Solar System
Analysis of samples brought back to Earth from the Ryugu asteroid reveals what its discoverers believe are the oldest solids in the Solar System so readily available for study.
The work — published by Tohoku University scientists in Nature Communications — focused on spherical mineral grains, called chondrule-like, and calcium-aluminum-rich inclusions (CAIs).

Mars, because of its proximity and Earth-like environment, has received the most attention and has been explored using (sub)surface sampling and analysis.

For radioastronomers, the far side of the Moon could be the last unspoilt refuge in the Solar System.
But an upcoming boom in lunar exploration could put that at risk. In the next ten years or so, the Moon will be the target of hundreds of orbiters and landers, each of which could create radio noise.

But would you be able to tell whether a particular geological feature was from our planet or another object in the solar system ?
MailOnline has put together a selection of images from Earth and beyond to test your knowledge about whether you're looking at our world or the likes of Mars , Venus or one of the many distant moons in the solar system.
