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 would be just the second example of three gravitationally bound space Rocks Found in the Kuiper belt, the doghnut-shaped region of eny Beyond the Orbit of Neptune.
The discovery could also challenge our undersrstanding of how kuiper belt objects (KBOS) Form.
If it is confirmed as a triplet, the system – designed 148780 Altjira – Could Offer Scientists a Chance to improve their models of how three gravitationally boundies Move Bodies.
This Puzzle, Known as the “Three-Body Problem,” Has been a challenge since isaac newton published his work “Principia” in 1687.
“The university is filled with a range of three-body systems, including the closest stars to earth, the alpha center system, and we're finding that the kuiper belt may be no no excaption Nelsen, A Physics and Astronomy Graduate of Brigham Young University in Provo, Utah, Said in a statement.

Three's company in the kuiper belt
Astronomers Dave Jewitt and Jane Lu Discovered The First ICY Body in the Kuper Belt, Known as 1992 QB1, In 1992.
Astronomers Estimate that Several Hundred Thousand More Kbos Measuring Over 10 Miles (16 Kilometers) in Diameter could lurk in this icy donut, which begins Around 2.8 Billion Miles (4.5 billion km) from.
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 altjira system sits in the middle of the kuiper belt, at Around 3.7 Billion Miles (6.0 Billion KM) from the Sun, or About 40 Times the distance between Earth and the Sun.
The hubble space telescope images initiated to show that the altjira system was composed of two kbos located about 4,700 miles (7,600 km) Apart.
When the team conducted reepeated observations of the Altjira System Object's Unique Co-Orbital Motion, however, they found the inner object is actually two bodies. These kbos are so close together that they can't be distinguished individually from
“With objects this small and far away, the separation between the two inner members of the system is a fraction of a pixel on hubble on's camera, so you have to use non-notn -imaging methods to discover that Triple, “Nelsen said.
It Took 17 Years of Data from Hubble and the Keck Observatories in Hawaii to Observe orbital Changes in the Altjira System and Make this determination. The data was added to Various Modeling Scenarios, with the most likely explanation being a triple-body system.
“Other Possibilites are that Inner Object is a contact binary, where two separete bodies believe they touch each each, or somenting that so hes Added.
Of 40 Multiple-body systems identified in the kuiper belt, this is just the second identified composed of composed of more than two objects. The Researchers Think these are available outliers and there are more multi-registraid systems out there in the outer reaches of the solar system, waiting to be discovered,
The hubble observations of the Altjira System, which Sugged it has a Third Occupant, support a theory of kbo creation that involves the direct gravitational collaps of matter in the message of matterous Sun Around 4.5 billion years ago.
This direct collapse pathway is similar to the formation process of stars, albeit it on a vastly smaller scale. Star formation from dense patches of gas and dust can also result in two and three-body systems.
The alternative kbo creation theory, which sees these icy space rocks created from collisions between larger bodies, would not create a three-body arranges as the altjira system appraars to be.
The altjira system joins the dwarf planet pluto and the “space snowman” arrokoth, a contact binary composed of two touching space Rocks, as the Most Heavily Studies in the kuiver belt.
Nasa's new horizons probe flew by pluto in 2015 and arrokoth in 2019. Possible in the future.
Particularly exciting will be forthcoming observations of altjira conducted by
“Altjira has entered an eclipsing season, where the outer body passes in front of the central body,” Nelsen said. “This will last for the next 10 years, giving scientists a great options to learn more about it.” ,
