This image, which is claimed to show the mythical planet Nibiru (or HMO, for Heavy Mass Object), started doing the rounds recently. I became aware of it yesterday, in a Facebook post and briefly pointed out why it had to be a fake.
The purported object is a crescent, yet is supposed to be outside of Earth's orbit, it is impossible for any object outside of Earth's orbit to be a crescent. To be a crescent, the object must be nearly between us and the Sun (try this out with a torch and two tennis balls to confirm it for yourself)...
