Scientists discover the stone more than a kilometer from the solar system
Scientists at the National Astronomical Observatory of Japan discovered a circular disk of 1.3 kilometers of rock located in the Kuiper belt which orbits around the sun. The discovery was published in Nature Astronomy.
According to the average RT, this belt has small bodies that are considered to be the remnants of the solar system formation, and scientists are studying it for more detailed information about the development of our system and how the planets were formed.
To discover this body, researchers used a method called "star occultation". Astronomer Ko Arimatsu placed a telescope across the roof of the school on Miyako Island, Okinawa, where he spent sixty hours studying two thousand stars.
After reviewing the information collected, they noticed that the star was hidden at 1.3 kilometers. It is the first body that is revealed from this kind, and it seems to indicate that there are more stones like this.
"If this is true detection of Kuiper's Belt Objects, it means that the planetary stage before its uncontrolled growth phases became objects within a kilometer of the primary outer solar system and remains a significant population. The current Kuiper belt," said Arimatsu, according to the Universe Today page.
