It's a new type of three-body problem for astronomers, who used the Hubble Space Telescope to determine that twin asteroids ...

Early in our Solar System’s history, bits of icy debris were scattered and then gradually coaxed into a spiral alignment in the Oort Cloud.

in which three small rocky bodies would not be the result of a collision in a busy Kuiper Belt, but instead form as a trio directly from the gravitational collapse of matter in the disk of ...

A newly identified Kuiper Belt trio, possibly only the second of its kind, could provide strong evidence that these distant ...

The puzzle of predicting how three gravitationally bound bodies move in space has challenged mathematicians for centuries, and has most recently been popularized in the novel and television show "3 ...

Most of the long-period comets in the Solar System come from the outer Oort Cloud. The inner region is much more stable. It's ...

The solar system extends beyond the Kuiper Belt and the scattered disc to the hypothesized Oort Cloud, an icy shell that might define the edge of the sun’s influence. Here, gravity weakens, and the ...

The new Hubble breakthrough offers key insights into a KBO formation theory in which the three small, rocky bodies would not have formed as the result of collision in the busy Kuiper belt, but rather ...
