Arrokoth averages around minus-384 degrees, but warms to minus-352 degrees if you stand directly under a high sun. That's just 76 degrees above absolute zero (minus 460 degrees), the coldest ...

Kuiper Belt Object Arrokoth, the farthest object ever explored by a spacecraft, likely tastes sweet — and soapy.

The Kuiper Belt object named "486958 Arrokoth," or simply "Arrokoth," may have more in common with a snowman than just its shape. New research suggests there's ancient ice locked within its frosty ...

The object, named Arrokoth, is an icy body that looks like two irregular M&Ms stuck together. When New Horizons took close-up photographs of it in 2019, planetary scientists were puzzled by its ...

Observations of the Kuiper Belt object Arrokoth suggest it formed from an assembly of similarly sized objects, brought together at low speeds in a local area undergoing gravitational collapse.

When NASA's New Horizons spacecraft flew past Pluto, its next destination was something even more surprising—Arrokoth, a mysterious object in the Kuiper Belt. This video explores what makes ...

Researchers from Brown University and the SETI Institute found that the double-lobed object, which is officially named Kuiper Belt Object 486958 Arrokoth and resembles a snowman, may have ancient ...

A recent study found that Arrokoth, a weirdly-shaped dwarf planet in the Kuiper Belt, gets its distinctive reddish coloration from complex hydrocarbon molecules, which form when cosmic rays and ...

Primitive ices and gas from the earliest days of the solar system can remain trapped inside deep-space objects like comets and Kuiper Belt Objects (KBOs) for billions of years. That’s the ...

The team believes that Arrokoth is a "primordial" object, being largely unaffected by other objects in the past 4.6 billon years. That makes it pretty useful for studying the early Solar System ...
