Researchers use the Subaru Telescope in Hawaii to find a small object on the outer edge of the Solar System. Nicknamed ...

New discoveries of objects in the Kuiper Belt have also presented challenges for the Planet Nine theory. The latest is known ...

The scale of the outer belt is around twice that of our solar system's Kuiper Belt. The inner belts were revealed by the telescope for the first time.

Scientists believe that Kuiper Belt objects (KBOs) are primitive and icy remnants from the early days of the solar system, about 4.5 billion years ago. They formed from leftover material after the ...

For context, the farthest known planetary body in the solar system is Pluto, which orbits approximately 39 AU from the sun, and is also part of the Kuiper Belt, which scientists estimate extends ...

So, New Horizons would stop observing Kuiper Belt objects and its outer solar system experts would be dismissed from the team, leaving only the heliophysics staff.

It is plausible that a primordial planetary body could survive in the distant Kuiper Belt as a Kuiper Belt planet, as many such bodies existed in the early solar system,” they wrote in their ...

Beyond the orbits of the eight planets in our Solar System, several distant objects make up the Kuiper Belt. The extent of this region has been estimated based on the discovery of such objects ...

Launched in 2006, the probe was the first to get an up-close look at Pluto, a resident of the Kuiper Belt, and serves as astronomers' eyes at the edge of the solar system.
