Some may be over 10 miles wide. Most small bodies in the Kuiper Belt form in pairs. Scientists used to think this happened through random collisions. But Altjira supports a different theory.

So far, about 40 binary systems have been identified in the Kuiper Belt. With two triple systems now strongly suspected, scientists believe there could be many more waiting to be discovered.

The Kuiper Belt is thought to stretch as far as 4.6 billion miles (7.4 billion km) from the sun, which is around 50 times the distance between Earth and our star.

The only Kuiper Belt objects that have been explored in detail are Pluto and the smaller object Arrokoth, which NASA's New Horizons mission visited in 2015 and 2019, respectively.

A new study from BYU professor of physics and astronomy Darin Ragozzine and former undergraduate student Maia Nelsen provides new insight into the structure of objects in the Kuiper Belt. Using data ...
