What if I told you… the scariest thing in space isn’t a black hole? Black holes are terrifying—gravity so strong not even light can escape. But there’s something even worse. It’s called a rogue planet. These are massive planets drifting through space… completely alone. No star. No light. Just darkness. Now imagine this: one suddenly enters our solar system. We wouldn’t see it coming—because it doesn’t reflect light. But its gravity? That’s the real danger. It could pull Earth out of orbit
