🪐 Comet 109P/Swift-Tuttle, the source of the annual Perseid meteor shower, is considered one of the most dangerous known objects crossing Earth's orbit. Its nucleus is about 26 kilometers wide—much larger than most hazardous asteroids—and its orbit brings it close to Earth every 133 years, so astronomers keep a close watch since a future impact would release energy far beyond any in recorded history. ✨ #comet⚡#Perseids⚡#impact⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels
