SAN ANTONIO – February 28, 2016: New Horizons, using data from Southern Pluto in Charon in 2015, scientists led by Southwest Research Institute have discovered indirect objects. The Kuiper small object tape (KBOs) evidence of the minority is the image of New Horizons, a figure that explains the dearth of a small crater with the largest satellite in Pluto, Charon, a stirrer with a diameter of 300 meters and 1 mile (91 meters and 1.6 km) it must be.

The Kuiper Belt looks like a frozen body beyond Neptune's orbit. Because the objects of the small Kuiper ribbon were some of the original "feedstock" of the planet, the research provides new insights on how to create the solar system. This research was published on March 1 of the prestigious magazine Science.

"The smaller objects of the Kuiper Belt are very small to see with remote telescopes," said Dr. Swri Kelsi Singer, lead author of the paper and researcher at NASA's New Horizons mission. "The New Horizons and the collection of data directly through the Kuiper Belt were the key to learning about the big and small bodies of the Belt."

"This new discovery of New Horizons has deep implications," added the main researcher of the mission, Dr. Alan Stern, also from Swri. "New Horizons reveals a great detail on Pluto, its moon and, more recently, the Ultimate Thule called KBO, according to the Singer group, which revealed the main details on the population of the KBO on the scales.

The craters of solar system objects record the influence of small bodies, providing advice on the history of the object and the space of the solar system. Because Pluton Earth is so far away, the planet's little dwarf surface was known until 2015. Pluton and Charon surfaces have many features: 13,000 feet (4 km) and mountains with large nitrogen ice glaciers. Pluto's geological process has eroded or altered some of its impact history, but relative relativity of Charon's relative geological impact has been a stable record of impacts.

"The most important part of the New Horizons mission is to better understand the Kuiper Belt," said Singer, a scientist at Saturn and Jupiter's geological investigations, to understand the superficial processes observed in the KBO. "This is a successful pioneer of Ultima Thule this year, which consists of three planetary surface areas analyzed, which uses data from the flyby of Pluton-Charon, which is indicated by less craters than expected.

Typical models of the planet show about 4,600 million years ago as a result of the gravity of the collapse of a giant molecular cloud. The sun, planets, and other objects were formed as a cloud material collapse, respectively. Different models affect the population and location of the solar system objects.

"This astonishing stunning little KBO changes the Kuiper belt, and its formation or evolution, or both, is somewhat different than the asteroid belts between Mars and Jupiter," Singer said. "Perhaps the asteroid belt is slightly lower than the Kuiper edge, because the inhabitants have a greater experience because they make smaller objects smaller."
