On a frigid orbit beyond Neptune, some of the solar system’s smallest worlds project a strange silhouette. Two rounded lobes, pressed together with a narrow “neck,” like a snowman that never melted.

Deep within the Kuiper belt, some small worlds look like they were assembled from two mismatched snowballs pressed together.

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 ...

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

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

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

The finding, published in the journal Monthly Notices of the Royal Astronomical Society, offers an explanation based on a surprisingly simple process: gravitational collapse. For years, the scientific ...
