A powerful new telescope in Chile is already changing how we see our Solar System. On April 2, 2026, scientists said that the Vera C. Rubin Observatory had found more than 11,000 new asteroids. The data were checked by the International Astronomical Union’s Minor Planet Center. This was the biggest single group of asteroid discoveries sent there in the past year. Even more amazing, these discoveries came from early test and optimization observations, before Rubin’s main 10-year sky survey has fully started. (rubinobservatory.org)
An asteroid is a small rocky body that moves around the Sun. Rubin did not only find new ones. In about a month and a half, it collected around one million observations of over 11,000 new asteroids and more than 80,000 already known asteroids. Among the new objects were 33 near-Earth objects. These are asteroids or comets that come relatively close to Earth’s orbit. The good news is that none of these 33 objects are dangerous to Earth, and the largest is about 500 meters wide.

Rubin also found about 380 trans-Neptunian objects. These are icy worlds far beyond Neptune. Two of them, called 2025 LS2 and 2025 MX348, travel on very long, stretched-out paths. At their farthest points, they go about 1,000 times farther from the Sun than Earth does. That puts them among the 30 most distant minor planets known. Scientists hope discoveries like these will help explain the history of the Solar System and maybe even give clues about a possible distant ninth planet. (rubinobservatory.org)
Why is Rubin so good at this? It has a large mirror, the world’s most powerful astronomical digital camera, and fast software that can spot faint moving objects in a busy sky. The observatory, named after astronomer Vera Rubin, is expected to scan the Southern Hemisphere sky night after night for ten years. Scientists think it could discover nearly 90,000 more near-Earth objects in the future. For people who love space, this feels like the beginning of a very big adventure.
