Scientists find the rock more than a kilometer at the boundary of the solar system
Scientists from the Japanese National Astronomical Observatory discovered a 1.3-kilometer wide rock that is located in the Kuiper band, a peripheral disk it orbits the sun. The discovery was published in the journal Nature Astronomy.
According to the middle RT, there are small bodies that are supposed to be the remains of the solar system, and scientists are studying it to get more detailed information about the evolution of our system and how the planets were created.
To discover this body, scientists used a technique called "star cover". Astronomer Ko Arimatsu installed two telescopes on the roof of a school on Miyako Island, Okinawa where he studied two thousand stars for sixteen hours.
In reviewing the collected information, they noticed that the star was hidden by a 1.3km wide object. It is the first body that is discovered by this type and it seems to indicate that there are more rocks like this.
"When it comes to actually detecting objects in the Kuiper Belt, it means that the plantesimals have become kilometer-sized objects in the primary outer solar system and remain as a significant population of the current Kuiper Belt," says Arimatsu, according to Universe Today.
