What is Ryugu and bennu?
Bennu and Ryugu are two rubble-pile asteroids that were recently photographed by unmanned spacecrafts. Both asteroids have a distinctive diamond shape, the formation of which has puzzled scientists. They went on to simulate the asteroids using this model, which supported their hypothesis.
Why is Ryugu an asteroid?
Why it matters — For scientists, asteroids like Ryugu represent unique archives from the early days of the Solar System, material kept in a deep freeze, and therefore unchanged, from the time before planets formed. The Ryugu sample is the second of its kind ever returned to Earth.
What is Ryugu made of?
The carbonaceous, or C-type, asteroid spins like a top as it hurtles through space, and like other C-type asteroids, Ryugu likely contains material from the nebula (giant cloud of dust and gas) that gave birth to the sun and its planets billions of years ago, scientists think.
How old is Ryugu?
Ryugu formed about 4.5 billion years ago and has retained its primitive composition – but C-type asteroids may not have remained completely unchanged during this time.
What is the gravity on Ryugu?
