Mirip Bumerang, Tata Surya Kita Ternyata Bisa Lempar Komet ke Galaksi – Kompas.com

by

Our solar system acts as a complex gravitational engine capable of ejecting comets into interstellar space, a phenomenon often compared to a celestial boomerang effect. Scientific observations confirm that interactions between long-period comets and the massive gas giants—particularly Jupiter—can alter orbital paths so significantly that these icy bodies are permanently expelled from our sun’s gravitational … Read more

NASA Ungkap Fakta Baru, Bumi Kini Tak Lagi Mengelilingi Matahari – CNBC Indonesia
