#HelioLinc3D found a near-Earth #asteroid ☄️ that older surveys had missed — one 600 feet long, the type that could devastate 💥 a large city 🏙️ . It was specifically designed for the #RubinObservatory in #Chile 🇨🇱. Telescopic 🔭 surveys have so far found more than 32,000 near- #Earth asteroids. Fainter asteroids ⚫ are mostly #undiscovered at present https://www.nytimes.com/2023/08/05/science/space-asteroids-rubin-heliolinc3d.html
