Why do we sample asteroids?
More samples from asteroids and comets will help determine whether life formed in space and was carried to Earth by meteorites. Another question under investigation is whether extraterrestrial life formed on other Solar System bodies like Mars or on the moons of the gas giants, and whether life might even exist there.
Why is Ryugu an asteroid?
In June 2018, the Japanese spacecraft Hayabusa2 arrived at the asteroid. After making measurements and taking samples, Hayabusa2 left Ryugu for Earth in November 2019 and returned the sample capsule to Earth on 5 December 2020….Saxa.

What type of asteroid is Ryugu?
carbonaceous
“I’m very hopeful our results will be helpful for the sample team,” Yokota says. Ryugu’s known as a C-type, or carbonaceous, asteroid, meaning its rocks and pebbles are packed with carbon molecules, contributing to its sooty coloration.
What can we learn from asteroid samples?
The biggest reason as to why we study asteroids is because they can tell us about the origins of the Solar System, as they are considered to be the building blocks of the planets. In planetary formation, lumps of rock, such as asteroids, coalesce to create minor planets and eventually planets.
Why was Bennu chosen for the mission?
Scientists chose Bennu as the target of the OSIRIS-REx mission because of its composition, size, and proximity to Earth. Bennu is a rare B-type asteroid (primitive and carbon-rich), which is expected to have organic compounds and water-bearing minerals like clays.
What did Japanese scientists want to learn about Ryugu?
In addition to helping scientists build a picture of how planets formed in our early Solar System, Ryugu may contain clues to the origins of life on Earth. Figuring out how hydrogen, carbon, and nitrogen ended up on Earth is an essential part of understanding the origins of water and life on our planet.
Why was Ryugu chosen?
Ryugu was chosen as the Hayabusa2 mission target because of its proximity to Earth and because it is one of these potentially life-giving C-type asteroids. The Ryugu sample is the first-ever C-type asteroid that scientists will be able to study firsthand.
What did Hayabusa2 find why does it matter?
Boulders on asteroid Ryugu are surprisingly fluffy, Japan’s Hayabusa2 probe finds. The rocks are about as porous as the building blocks of planets. Boulders on asteroids can be three-quarters hollow or more, a discovery that could help yield insights on the way in which Earth and other planets formed, a new study finds …
