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 ...

Trying to understand the makeup and evolution of the solar system's Kuiper belt has kept researchers busy since it was hypothesized soon after the discovery of Pluto in 1930. In particular, binary ...

A new study from BYU professor of physics and astronomy Darin Ragozzine and former undergraduate student Maia Nelsen provides new insight into the structure of objects in the Kuiper Belt. Using data ...

First detected in 2004, the dwarf planetHaumeaquickly stood out due to its rapid rotation and elongated form. But the 2017 discovery of a ring system around it added a new level of complexity to an ...

Survey observations using the Subaru Telescope’s ultra-widefield prime focus camera have revealed that there may be a population of small bodies further out in the Kuiper Belt waiting to be discovered ...

Can asteroids orbit each other in pairs of three, also called a three-body or triple system, like stars? This is what a recent study published in The Planetary Science Journal hopes to address as a ...

You are probably pretty familiar with the name Subaru because of the cars it makes. But as with any Japanese word, there's more to it than meets the eye: it’s used to depict more than just the ...

Scientists have recently unveiled a remarkable discovery in the outer reaches of our solar system: a space fossil located 4 billion miles past Pluto, covered in unidentified organic molecules. This ...

There may be a warp in the Kuiper Belt, possibly caused by “Planet Y” — a Mercury-to-Earth-sized world that orbits the sun way beyond the orbit of Neptune. Is there a mysterious “Planet Y” orbiting ...

The cold and shadowy fringe of the solar system known as the Kuiper belt is generating increasing debate among scientists as data accumulates on the growing population of objects discovered there. Now ...

The trans-Neptunian region, extending beyond Neptune, represents a primordial reservoir of icy and rocky bodies that have remained relatively unchanged since the Solar System’s formation. Central to ...
