Scientists detect rock more than a kilometer at the edge of the solar system
Scientists at Japan's National Astronomical Observatory have detected a 1.3 km wide rock located in the Kuiper belt, a circumstellar disk which orbits around the sun. The discovery was published in the journal Nature Astronomy.
According to the average RT, in this belt there are small bodies believed to be remnants of the formation of the solar system and scientists study it to get more details of the evolution of our system and how the planets formed.
To detect this body, the researchers used a technique called "stellar occultation." The astronomer, Ko Arimatsu, installed a pair of telescopes on the roof of a school on Miyako Island, Okinawa, where he studied two thousand stars for sixty hours.
In reviewing the information collected, they noticed that a star was hidden by an object 1,3 km wide. It is the first body that is discovered of this type and seems to point out that there are more rocks like this.
"If this is a true detection of objects in the Kuiper belt, this implies that the planetesimals before their uncontrolled growth phase have become objects the size of a kilometer in the primordial outer solar system and remain as a major population in the region. of Kuiper, "said Arimatsu, according to the Universe Today page.
