A rendering of the inner Solar System showing the asteroids discovered by Rubin in light teal. Known asteroids are dark blue. The rendering shows a total of almost 12,700 asteroids that were discovered with Rubin over the span of 1.6 years: 73 were discovered during the first early test observations using Rubin’s Commissioning Camera in late 2024 and released as part of Rubin’s Data Preview 1 in Summer 2025; 1514 were discovered during First Look observations in April and May 2025; and the recent 11,000+ asteroids were discovered using observations taken during Rubin’s early optimization surveys in Summer 2025.

Even before beginning formal science operations, the remarkable Rubin Observatory has already discovered 12,700 new asteroids.
It found 11,000 asteroids in just 6 weeks during an "optimization" shakedown.
