Astronomers using the Vera C. Rubin Observatory have discovered over 11,000 new asteroids, including hundreds of trans-Neptunian objects and 33 previously unknown near-Earth asteroids.<\/p>\n

The new dataset from the Vera C. Rubin Observatory comprises approximately one million observations, taken over the span of a month and a half, of over 11,000 new asteroids and more than 80,000 already known asteroids.<\/p>\n

The data were submitted to the International Astronomical Union\u2019s Minor Planet Center<\/a> (MPC).<\/p>\n

\u201cThis first large submission after Rubin First Look is just the tip of the iceberg and shows that the observatory is ready,\u201d said Rubin Solar System lead scientist Dr. Mario Juric, an astronomer at the University of Washington.<\/p>\n

\u201cWhat used to take years or decades to discover, Rubin will unearth in months.\u201d<\/p>\n

\u201cWe are beginning to deliver on Rubin\u2019s promise to fundamentally reshape our inventory of the Solar System and open the door to discoveries we haven\u2019t yet imagined.\u201d<\/p>\n

Among the newly-identified objects are 33 previously unknown near-Earth objects (NEOs), which are small asteroids and comets whose closest approach to the Sun is less than 1.3 times the distance between Earth and the Sun.<\/p>\n

None of the newly discovered NEOs pose a threat to Earth, and the largest is about 500 m wide.<\/p>\n

The dataset also contains roughly 380 trans-Neptunian objects (TNOs) \u2014 icy bodies orbiting beyond Neptune.<\/p>\n

Two of these TNOs \u2014 provisionally named 2025 LS2 and 2025 MX348 \u2014 have been found to be on extremely large and elongated orbits.<\/p>\n

At their most distant points, these two objects reach roughly 1,000 times farther away from the Sun than the Earth is, placing them among the 30 most distant minor planets known.<\/p>\n

\u201cSearching for a TNO is like searching for a needle in a field of haystacks \u2014 out of millions of flickering sources in the sky, teaching a computer to sift through billions of combinations and identify those that are likely to be distant worlds in our Solar System required novel algorithmic approaches,\u201d said Dr. Matthew Holman, an astrophysicist at the Harvard & Smithsonian\u2019s Center for Astrophysics.<\/p>\n

\u201cObjects like these offer a tantalizing probe of the Solar System\u2019s outermost reaches, from telling us how the planets moved early on in the Solar System\u2019s history, to whether a hitherto undiscovered 9th large planet may still be out there,\u201d added Dr. Kevin Napier, also from the Harvard-Smithsonian\u2019s Center for Astrophysics.<\/p>\n","protected":false},"excerpt":{"rendered":"Astronomers using the Vera C.
