Japanese scientists believe they know the origin of the German Ryugu asteroid – BGR

Hayabusa2's spaceship in Japan has been hanging around the asteroid now called Ryugu for several months. It arrived first in late 2018 and, in February, casting projections into the surface to collect a sample from the rock. There's still a lot of work to do but things are progressing very nicely.

Now, having learned more about the asteroid itself, Japanese scientists believe they know where the object came from, which cut down a “parent” asteroid which could have been in a pair. bigger cliffs. Deciding that Ryugu sources would not be easy, but the color of the asteroid has helped researchers to reduce things down a lot.

A new research paper published Science, an international team of scientists who describe various aspects of what they were able to see with photos from Hayabusa2. They've been able to make a decision that some parent water had been “sprinkled with water” and perhaps “rich molecules” too.

Ryugu is really dark with any level, and is thought to be one of the darkest elements of our entire solar system. Maybe that is hard to believe when you see images shot by Hayabusa2 but it is important to remember that the devices that the test machine is designed to specifically describe. dark of the rock.

As Science News Giving reports, the color of the rock helped scientists to find his parents just possible for two other known asteroids. The first is a 55-kilometer asteroid called Polana, and the second a 37-kilometer smaller rock called Eulalia. Both are larger than the 900-meter-wide, and are similar in character.

Hayabusa2 will finally return to the Earth, only after collecting more samples from Ryugu. These examples will tell many researchers about the history of the rock and may help them to fall down.
