🪐 In 2013, astronomers tracked asteroid (367943) Duende, a 30-meter-wide space rock that passed just 27,700 kilometers above Earth's surface—closer than many weather satellites. Duende’s near miss was remarkable not only for its proximity, but because it approached from the Sun’s direction, making it hard to spot in advance and highlighting the ongoing challenge of detecting small but potentially hazardous asteroids before they pass close to our planet. ✨ #asteroids⚡#duende⚡#planetarydefense⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels
