This occurred a couple years ago, but it's making rounds online. A guy posted a video he filmed of a three Sun horizon! The video looks like some thing out of Star Wars. This optical phenomenon is called a Halo. It happens when sunlight interacts with ice crystals suspended in the atmosphere. It's very cool looking! Though if we really had three suns I don't think it would be very cool at all, it'd probably be pretty hot!
