Astronomers may have just identified a rare example of a "three-body problem" hiding in plain sight beyond the solar system's most distant planet. If the observation can be confirmed, it suggests that ...

The three-body problem is a physics conundrum that has boggled scientists since Isaac Newton's day. But what is it, why is it so hard to solve and is the sci-fi series of the same name really possible ...

The Kuiper Belt object Altjira was thought to be a binary, but closer analysis suggests that it is highly likely to be a triple system This raises the question of the three-body problem; if Altjira ...

"The universe is filled with a range of three-body systems, including the closest stars to Earth, the Alpha Centauri star system, and we're finding that the Kuiper Belt may be no exception!" When you ...

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 ...

New research suggests that a binary pair of Kuiper Belt objects, known as the Altjira system, is actually made up of three separate bodies orbiting one another in a complex triad. This rare orbital ...
