Chile’s asteroid-warning telescope spots the Solar System’s third interstellar visitor

The ATLAS survey telescope in Chile, built to warn about near-Earth asteroids, unexpectedly detected 3I/ATLAS, the third known interstellar object, whose hyperbolic trajectory indicates it is not from the Solar System and, based on motion modelling, may be older than the Solar System; the discovery shows planetary-defense instruments can also capture rare interstellar visitors and inform our understanding of galactic debris.

Loeb Suggests Hayabusa2’s Target Might Be a Soviet Relic, Not an Asteroid

Harvard astronomer Avi Loeb and colleagues speculate that 1998 KY26—the rapidly spinning object Hayabusa2 is set to study in 2031—could be a long‑lost Soviet spacecraft (Phobos 1) rather than a natural asteroid. The idea, based on suggested orbital similarities and size, is highly speculative and not yet peer‑reviewed; it aims to broaden the observational data considered when judging solar‑system objects, with Hayabusa2’s observations expected to help resolve the object's true origin.

Hayabusa2's Next Target Might Be a Soviet Space Relic, Not a Natural Asteroid

Hayabusa2 is heading toward the tiny, fast-spinning asteroid 1998 KY26, but a yet-to-be-peer-reviewed paper by Avi Loeb and collaborators speculates the object could be a long-lost Soviet spacecraft from the Phobos 1 mission rather than a natural body. The theory draws parallels in size and shape and notes potentially converging orbits, though the idea remains highly speculative and distant; if true, it could fuel debates about the nature of ‘Oumuamua and prompt scientists to consider man-made objects in searches for unusual space rocks. Awaiting Hayabusa2’s 2031 observations to resolve the mystery.”,

Oumuamua: The First Interstellar Visitor Still Defying Explanation

In 2017, the first confirmed interstellar object, Oumuamua, passed through the Solar System on a hyperbolic path and showed a tiny non-gravitational push without a visible tail. Natural explanations (e.g., venting hydrogen or nitrogen ices) exist, and Avi Loeb's artificial-origin idea remains controversial; since then Borisov and ATLAS behaved like comets, but Oumuamua remains an unresolved puzzle, underscoring data limits and the hope that Rubin Observatory will help settle what it could not.

NASA Debunks Alien Origin Claims of Interstellar Comet 3I/ATLAS

Interstellar objects like 3I/ATLAS, Oumuamua, and Borisov are the most common objects in the Milky Way galaxy, with estimates suggesting there are trillions of them, but they are difficult to detect due to their small size and dark nature. Upcoming surveys like the Vera C. Rubin Observatory's LSST are expected to significantly increase detection rates, providing opportunities to study the galaxy's chemical evolution and potentially retrieve samples from distant planetary systems.

Origins and Destinations of Interstellar Objects 1I/'Oumuamua, 2I/Borisov, and 3I/Atlas

Origins and Destinations of Interstellar Objects 1I/'Oumuamua, 2I/Borisov, and 3I/Atlas

Scientists have traced the origins of three interstellar objects—Oumuamua, Borisov, and Atlas—finding they come from different regions of the Milky Way and are of varying ages, with Atlas being the oldest. Oumuamua is currently leaving our solar system, Borisov is in the constellation Ara, and Atlas is headed towards the inner solar system, possibly as a comet or even an alien spaceship. These objects provide insights into other star systems and the galaxy's history.

Tracking the Journey of Interstellar Objects 1I/'Oumuamua, 2I/Borisov, and 3I/Atlas

Astronomers have tracked the trajectories of three interstellar objects—'Oumuamua, Borisov, and Atlas—revealing they originated from different regions and ages within the Milky Way, providing insights into the diversity of planetary systems and galactic dynamics. These objects serve as natural probes into other star systems, and future observations and missions are expected to expand our understanding of interstellar material and its origins.

Scientists Debate Alien Origins of Interstellar Meteors and Objects

Astronomers believe small interstellar objects frequently pass through our solar system and hit Earth, but detecting these tiny, fast-moving bodies remains challenging. Recent discoveries of interstellar objects like 'Oumuamua and Borisov support the idea of a continuous influx of alien debris, yet unambiguous detection of interstellar meteors in Earth's atmosphere has so far eluded scientists. Increasing sky surveillance could help capture these cosmic visitors and deepen our understanding of other star systems.
