Galaxy Quote by Michio Kaku
“Most Jupiter-sized planets orbit the mother star in a highly elliptical orbit. This means they will often cross the orbit of any Earth-like planet and fling it into outer space, making life impossible. But our Jupiter travels in a near-perfect circular orbit, preventing a collision with any Earth-like planet, making life possible.”
About This Quote
Source Lecture: Scientific American, 2015
Jupiter-like planets on elliptical paths can destabilize Earth-like worlds, while a circular orbit protects habitability.
In simple terms: Elliptical orbits threaten life; circular orbits protect it.
