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

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 ...

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 ...

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 ...

This time last year, the New Horizons mission visited the furthest object humanity has ever reached — Arrokoth, beyond the orbit of Pluto in an area called the Kuiper Belt. Now, scientists have ...

Arrokoth has a geometric albedo of p_V = 0.21_ (-0.04)^ (+0.05) at a wavelength of 550 nm and ~0.24 at 610 nm. Arrokoth’s geometric albedo is greater than the median but consistent with a distribution ...

Just over a year ago, courtesy of NASA’s New Horizons mission, we were treated to images of 2014MU69, a small object 6.6 billion kilometers from the sun – making it the most distant object to have ...

A new study posits that the large, approximately 5-kilometer-long mounds that dominate the appearance of the larger lobe of the pristine Kuiper Belt object Arrokoth are similar enough to suggest a ...
