Fresh mapping of the outer solar system has revealed a previously unseen pattern in the Kuiper Belt, the icy ring of debris beyond Neptune that has long been treated as a relatively simple torus of ...

A brand-new group of frozen objects, orbiting the sun out beyond the distant Kuiper Belt, has been spotted by the Subaru telescope, working with NASA's New Horizons mission to find new targets for the ...

A vast region of our solar system, called the Kuiper belt, stretches from the orbit of Neptune out to 50 or so astronomical ...

Astronomer used to think that the Kuiper Belt was a few hundred times larger than the Asteroid belt. They thought it was a donut shaped structure that started at Neptune and extended out 2 billion ...

Japanese researchers have used computer simulation and the orbits of several large objects past Neptune to calculate that there is Kuiper Belt planet (KBP) 1.5–3 times as massive as Earth, located at ...

In the outer reaches of the Solar System, beyond the ice giant Neptune, lies a ring of comets and dwarf planets known as the Kuiper Belt. The closest of these objects are billions of kilometers away.

Arrokoth, a distant object in the Kuiper Belt, contains significant amounts of organic molecules, including complex sugars, giving it the new nickname "Sugar World," a study has reported. The study, ...

(SwRI) and the Observatoire de la Côte d’Azur provides an explanation for one of the more mysterious aspects of the population of objects beyond Neptune. In doing so, it provides a unique glimpse into ...

On a Hawaiian mountaintop in the summer of 1992, a pair of scientists spotted a pinprick of light inching through the constellation Pisces. That unassuming object — located over a billion kilometers ...
