In A Nutshell Arrokoth, a snowman-shaped object billions of miles from Earth, is one of the oldest and least-disturbed relics of the early solar system Scientists have long debated whether its two ...

Scientists have long know many objects floating at the solar system's out edges resemble snowmen, but the reasons why were never clear. Now a student at Michigan State University has created the first ...

Astronomers had decent guesses about how these peanut-shaped asteroids formed but couldn’t get the physics to work—until now.

Researchers simulated how gravitational collapse forms two-lobed contact binaries in the Kuiper Belt without destructive ...

Research adds weight to theory Arrokoth’s two lobes produced by gravitational collapse – and reveals process ...

A new study from researchers at the Southwest Research Institute has unearthed a fascinating discovery about Arrokoth, a trans-Neptunian object made famous by the New Horizons probe on New Year’s Day ...

The many millions of bodies populating the Kuiper Belt beyond Neptune's orbit are yet to reveal many of their secrets. In the 1980s, the space probes Pioneer 1 and 2 as well as Voyager 1 and 2 crossed ...

A new study led by Southwest Research Institute (SwRI) Planetary Scientist and Associate Vice President Dr. Alan Stern posits that the large, approximately 5-kilometer-long mounds that dominate the ...
