地球低軌道で交通事故が起きる？ 科学者たちが懸念する｢人工衛星が多過ぎ｣問題 | インターネット | 東洋経済オンライン

This page discusses concerns about overcrowding in Earth's low orbit due to increasing numbers of artificial satellites. NASA estimates approximately 40,000-50,000 trackable objects currently orbit Earth, with the majority in low orbit. Private companies like SpaceX's Starlink and Amazon's Leo plan to launch thousands to over 10,000 satellites, while Elon Musk recently announced plans for approximately 1 million AI-equipped satellites. The increasing congestion raises concerns about potential collisions in orbital "traffic accidents." A 2009 collision between an American and Russian satellite created over 2,300 debris fragments, with scientists warning of risks like Kessler Syndrome.
