"Phew! NASA Rules Out Asteroid Smashup on the Moon in 2032" by @universetoday / @alanboyle - Astronomical observations of #asteroid #2024YR4, including from #NASA #WebbSpaceTelescope🔭 #JWST, refined its orbit estimate to rule out impact with the #Moon on its Dec 22, 2032 flyby. Possibility of Earth impact on that pass was already ruled out in April 2025. The 60m diameter rock would be a serious threat. https://www.universetoday.com/articles/phew-nasa-rules-out-asteroid-smashup-on-the-moon-in-2032 #astronomy #PlanetaryDefense #PlanetaryDefence #LowFlyingRocks #space

"Asteroid 2024 YR4's collision with the moon could create a flash visible from Earth, study finds" by @LiveScience - #Asteroid #2024YR4 was briefly subject of concern until Earth impact was ruled out. It's still being studied for potential impact with the #Moon on Dec 22, 2032. New paper estimates impact areas, all on the side facing Earth. A tiny fraction might be in darkness, visible without optics. https://www.livescience.com/space/asteroids/asteroid-2024-yr4s-collision-with-the-moon-could-create-a-flash-visible-from-earth-study-finds #astronomy #PlanetaryDefense #PlanetaryDefence #LowFlyingRocks #space

"Apophis flyby in 2029 will be the first time a potentially hazardous asteroid has been visible to the naked eye" by @LiveScience - #Asteroid #99942Apophis will make a close pass by Earth on April 13, 2029. Earth will not be affected. But scientists are gearing up to observe how Earth's gravity changes the orbit of the asteroid, and possibly deforms its shape. There's so much to learn for #PlanetaryDefense / #PlanetaryDefence for the future. https://www.livescience.com/space/asteroids/apophis-flyby-in-2029-will-be-the-first-time-a-potentially-hazardous-asteroid-has-been-visible-to-the-naked-eye #astronomy #LowFlyingRocks
