New simulations reveal that around 1 million "macroscopic" objects from our closest stellar neighbors, the Alpha Centauri ...

With 3.2 billion pixels and a decade-long search, the Rubin Observatory will reveal what’s been hiding in plain sight.

Oumuamua could not have obtained its velocity from any known object in the Solar System. We have a complete census of objects big enough to do it within a volume out to 21 AU.

Our solar system may not be as isolated as we once thought. According to a new study, more than 1 million interstellar objects could be lurking in the outer reaches of our cosmic neighborhood ...

Predictions of the LSST Solar System Yield: Near-Earth Objects, Main Belt Asteroids, Jupiter Trojans, and Trans-Neptunian Objects. The Astronomical Journal (submitted to arXiv) , 2025 DOI: 10.3847 ...

The speed and trajectory of the object A/2017 U1 suggested that it did not come from our Solar System, and that it will leave our Solar System again. ‘Oumuamua, as it is now called, was our ...

And if Peñarrubia is right, then we have plenty of interstellar objects in our own Solar System, just waiting to be found and studied — if we can find them, that is.

TNOs, planetary bodies located beyond Neptune, are icy remnants of the early Solar System. Deflected into orbits closer to the Sun in the region of the giant planets, some become Centaurs ...

For years, astronomers have been searching for a mysterious ninth planet lurking in the dark outer reaches of our solar ...

However, the odds of encountering one of these objects within the heart our solar system remain exceedingly low, with only a one-in-a-million chance that an interstellar visitor is located within ...

37,000 trans-Neptunian objects, residents of the distant Kuiper Belt — nearly 10 times the current census — shedding light on Neptune’s past migration and the outer solar system’s history.
