The puzzle of predicting how three gravitationally bound bodies move in space has challenged mathematicians for centuries, ...

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

NASA's Hubble Space Telescope has discovered that a system of asteroids in the distant Kuiper Belt may be triplets, not twins as previously suspected. If so, the stable trio of icy space rocks ...

Scientists have discovered a potential three-body system in the Kuiper Belt, the Altjira system, challenging planet-formation ...

Over the last 10 years, the Hubble Space Telescope has taken pictures of Altjira and a 2011 study found that it appears as ...

The Kuiper Belt is a vast region beyond Neptune filled with icy remnants from the early solar system. Over 3,000 KBOs have ...

Can asteroids orbit each other in pairs of three, also called a three-body or triple system, like stars? This is what a ...

NASA scientists have discovered Altjira system, a group of 3 space rocks in Kuiper Belt, providing evidence for the theory of ...

W. M. Keck Observatory’s laser guide star adaptive optics (LGS AO) system uses a laser to create an artificial star to measure for atmospheric distortions. This results in sharp, high-resolution ...

After 17 years of observation, researchers are certain that what they thought was a group of two celestial bodies is actually ...

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

There's no problem, however, with what a team of researchers say is likely a stable trio of icy space rocks in the solar system's Kuiper Belt, found using data from NASA's Hubble Space Telescope ...
