A new report on the enigmatic interstellar visitor 3I/ATLAS has revealed deeper insights into the object’s behavior, which include signs of non-gravitational motion during its recent closest approach to the Sun.
Presently, most astronomers maintain that the space object, discovered in July 2025, is a natural comet, based on a growing body of data that confirms this interpretation. The object is the third known interstellar visitor that has entered our planetary neighborhood from another star system.
3I/ATLAS is also helping confirm data that suggests such objects probably make appearances far more frequently in our Solar System than previously known. With its glowing gassy envelope—what astronomers call a coma—and other key traits that have manifested as the object has moved closer to the Sun, little doubt has been left about the interstellar visitor’s identity as a natural object.
However, there are still some experts who interpret its recent activity as being noteworthy indicators—if additional related phenomena were to be confirmed in future observations—which some might expect to associate with objects of technological origin. So what does the latest data reveal, and why does it still have some astronomers divided over whether 3I/ATLAS might show signs associated with intelligent life?
What the New Report Reveals
A recent report by researcher Davide Farnoccia with NASA’s Jet Propulsion Laboratory offers some of the latest data on the gravitational characteristics displayed by 3I/ATLAS during its journey through our Solar System.
Farnoccia specializes in the study of small objects and their orbits, which includes “nongravitational perturbations” some space objects display, as well as whether some near-Earth objects (NEOs) may pose an impact hazard to Earth.
According to Farnoccia’s report, 3I/ATLAS follows a hyperbolic orbit, displaying an eccentricity of e = 6.1373 (rounded). This figure is important, as it significantly exceeds the accepted value of 1 that astronomers recognize as being required to escape the Sun’s gravity. This means that the object’s trajectory confirms that 3I/ATLAS is not gravitationally bound to our Solar System, confirming astronomers’ suspicions that once it completes its recent planetary drive-by visit, the object will continue back into interstellar space.
