Scientists detect rock of more than one kilometer in the limit of the solar system

Scientists from the National Astronomical Observatory of Japan have detected a 1,3-kilometer-wide rock located in the Kuiper belt, a circunestelar disk which orbits around the sun. The discovery was published in the journal Nature Astronomy.

According to the RT medium, in this belt there are small bodies that are thought to be remains of the formation of the solar system and scientists study it to obtain more details of the evolution of our system and how the planets formed.

To detect this body, the researchers used a technique called "stellar concealment". The astronomer Ko Arimatsu installed a pair of telescopes on the roof of a school on the island of Miyako, Okinawa, where he studied two thousand stars for sixty hours.

When reviewing the collected information, they noticed that a star was hidden by an object of 1.3 kilometers in width. It is the first body that is discovered of this type and seems to point out that there are more rocks like this one.

"If this is a true detection of objects in the Kuiper belt, this implies that the planetsimal before their phase of uncontrolled growth became objects of the size of one kilometer in the primordial external solar system and remain as an important population in the current Kuiper belt, "said Arimatsu, as reported on the Universe Today page.
