Astronomers at the Vera C. Rubin Observatory have identified over 11,000 new asteroids, including hundreds of trans-Neptunian objects and 33 previously unknown near-Earth asteroids (NEOs).

The Vera C. Rubin Observatory has compiled a groundbreaking dataset featuring nearly 1 million observations of over 11,000 newly discovered asteroids along with more than 80,000 known asteroids collected over a short period of six weeks.
This data has been submitted to the Minor Planet Center (MPC) as the observatory gears up for future discoveries.
Dr. Mario Juric, Rubin Solar System Principal Scientist and astronomer at the University of Washington, remarked, “This initial major submission following the Rubin First Look is just the beginning, demonstrating that the observatory is fully operational.”
“What once took years or even decades to discover, Rubin will unveil in mere months,” he added.
“We are on the path to fulfilling Rubin’s mission to revolutionize our understanding of the solar system and pave the way for groundbreaking discoveries yet to be anticipated.”
The newly cataloged objects include 33 previously unknown near-Earth objects (NEOs), which are classified as small asteroids or comets that come within 1.3 times the Earth-Sun distance.
Importantly, none of the newly found NEOs present any threat to Earth, with the largest measuring approximately 500 meters across.
This dataset also contains around 380 trans-Neptunian objects (TNOs), which are icy bodies orbiting far beyond Neptune.
Among these TNOs, two (tentatively designated 2025 LS2 and 2025 MX348) were observed in extensive and elongated orbits.
At their furthest points, these objects are nearly 1,000 times further from the Sun than Earth, ranking them among the 30 most distant known asteroids.
Dr. Matthew Holman, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, explained, “Searching for TNOs resembles looking for a needle in a haystack. We required innovative algorithms to assist computers in sifting through billions of combinations from millions of flickering light sources in the night sky to identify potential distant worlds in our solar system.”
“Such discoveries provide exciting insights into the outermost realms of the solar system, including how planets migrated during the early solar system’s formation and the lingering possibility of a still undiscovered ninth large planet,” Dr. Kevin Napier, also from the Harvard-Smithsonian Center for Astrophysics, added.
