Missing Planet Tiamat in Solar System



So here you have two definitions of a blue moon but the one for a calendar blue moon does not describe the true meaning of a blue moon. Here's why: We earthlings love to look up at the moon. So much does the moon enamor us; we write movies, songs and poems by the droves that contain the name of the earth's super satellite. A case in point is the fact that one of the biggest selling record albums of all time is Pink Floyd's "Dark Side of the Moon." Titan is certainly an exotic, fascinating, frigid oddball, that bears an eerie resemblance to the primordial Earth before life emerged and evolved on our planet (prebiotic). In fact, Titan is the only moon in our entire Solar System with a substantial atmosphere. It is also the only known world--other than Earth--where stable bodies of surface liquid exist.
