I don't even know enough about astronomy to be dangerous, although I've been fascinated by it since childhood. I follow most of the astronomy-related threads that show up here, Nibiru and Galactic Federation stuff excluded because those threads are always full of shit. In my almost six years here, I've seen Astro proven right every single time he's weighed in on something, and nothing but fail from everyone else. I trust his judgment, and you should, too. It'll save you a lot of time and panic.
