If found, this gassy, icy beast some 155 billion miles away from the sun would explain why some objects beyond the Kuiper Belt orbit so strangely. And that day could be soon. Or not, experts told ...

Trans-Neptunian Objects (TNOs) are celestial bodies located in the outer solar system, beyond the orbit of Neptune. This region, known as the Kuiper Belt, is home to a diverse array of icy bodies ...

Beyond Neptune lies the Kuiper Belt, a vast expanse of icy bodies that may hold clues to the solar system’s formation. These ...

Additionally, 80% of the largest objects in the Kuiper Belt have a large object rotating them like the Pluto-Charon dynamic, and "kiss and capture" events could have occurred in this region in ...

Pluto likely acquired large moon Charon in a “kiss and capture” collision billions of years ago. It may have created a subsurface ocean on the icy dwarf planet.

Pluto belongs to a group of objects that distantly orbit the sun called the Kuiper Belt, where thousands of icy remnants left over from the formation of the solar system linger. Eight of the 10 ...

New research suggests Pluto may have had a “kiss” with its largest moon billions of years ago in a harmless collision. The report, published in “Nature Geoscience,” describes how the ...

Venus, Jupiter, and Mars dominate the sky. Catch your last views of Saturn as early in the month, the Moon passes in front of ...

Dr. Franck Marchis, a senior planetary astronomer and director of Citizen Science at the SETI Institute, and Dr. Lauren Sgro, outreach manager for LaserSETI and astronomer at the SETI Institute, ...

"It's a pretty big question since a bunch of other large Kuiper Belt Objects also have large moons, so it seems like this is something that happens in the Kuiper Belt with some frequency ...

While Charon is currently listed as a satellite or moon by the International Astronomical Union (IAU), consideration is being given to it perhaps being classified as a dwarf planet in its own right, ...
