Objects larger than 140 meters 📏 are closely tracked as they could cause significant regional damage if they impact 💥, yet scientists estimate that only about 40% 📊 of these mid-sized #NEOs have been identified so far. Among the newly identified objects are 33 previously unknown #NEOs, the largest is about 500 meters wide. #Rubin is expected to reveal an additional 90,000 new NEOs, some of which may be potentially hazardous https://rubinobservatory.org/news/11000-new-asteroids

#LSST performs very well for large impactors ☄️, discovering about 79.7% of objects larger than 140 m before impact. Only 50.3% of 50–140 m impactors, 26.8% of 20–50 m impactors, and 10.5% of 10–20 m impactors are discovered 🔭 at all. About 60% of large impactors fail to reach a one-year warning threshold. Upper mid-size objects are usually discovered only a few months before impact 💥 https://www.newplanetarium.com/journal/2026-01-29

📸 Rubin’s First Look: A Sagittarius Skyscape
This wide-field view from the new Vera C. Rubin Observatory spans over 4 degrees in Sagittarius. It captures the Lagoon Nebula (M8) and Trifid Nebula (M20), two iconic regions of star formation in the Milky Way.

Most Venusian co-orbitals are nearly #invisible from Earth because they often remain in the #Sun’s glare ☀️. “While surveys like those from the #RubinObservatory 🔭 @VRubinObs may be able to detect some of these #asteroids ☄️ in the near future, we believe that only a dedicated observational campaign from a space-based 🌌 mission near #Venus could potentially map and discover all the still ‘invisible’ potentially #hazardous asteroids” https://dailygalaxy.com/2025/05/is-venus-hiding-a-deadly-threat-asteroids
