What would would the night sky look like if our planet was orbited by Mars, Jupiter, or a even a parallel Earth? Brad Goodspeed has created this nifty video imagining such a scenario.
Look how ominous Jupiter looks in orbit. I don't even want to imagine what all those werewolves would turn into on a "full Jupiter." Then again, I guess we would perpetually see a "full Jupiter."
