Even if you could travel at the speed of light, it would take over a year to reach the far edge of the Oort Cloud — a vast, icy shell believed to surround our entire solar system. But here’s the catch: 🔭 We’ve never actually seen it. The Oort Cloud is hypothetical — not because it’s science fiction, but because it’s too distant and faint for any telescope to observe directly. Still, the strange orbits of distant comets strongly suggest it's out there, silently holding the ancient leftovers of our solar system's formation. The edge of our solar system isn’t just far — it’s farther than you’ve ever imagined.
