It has a radius of 1.3 km. Japanese scientists published it yesterday in Nature Astronomy. It is the object farthest from the Earth that is found.
The solar system begins to discover its mysteries. On January 1, the NASA New Horizons, flight Ultima Thule and since then, the North American Space Agency has spread several images of this body, the most remote and primitive ever found by man.
The body without an atmosphere that is in the belt of the Kuiper it is a remnant of the formation of The solar system and her study emerges as a key issue for discovering the origins and evolution of our planet system.
Ultima Thule was formed before 4.500 million of years and is more than 1 billion kilometers of Pluto. It is their distance that makes their study more difficult because of their size, because these bodies are completely fragile and difficult to detect.
This is Bennu, the "asteroid of death" that may clash with the Earth
However, a group of Japanese astronomers managed to overcome this barrier and began a low cost asteroid research: two amateur telescopes, added to two commercial cameras, were enough to be able to investigate. On the terrace of a public center located on the island Mijako, in Okinawa, more than 2000 stars between June 2016 and August 2017, in order to identify the concealment.
The work gathered 60 hours of images that occupied 50 terabytes of raw data. His analysis meant that the first object was found outside Pluto, with a radius of 1.3 km width, and by its size and distance, the feat was twice as valuable.
According to what the specialized magazine publishes Nature Astronomy, Japanese astronomers launched a project called OASES, which worked through a coordinated system of several low-cost telescopes with a high speed and wide area for detecting stellar occlusions.
