What is the difference between a Lunar Eclipse and New Moon? They seem quite similar and there is often confusion between the two. A lunar eclipse happens twice a year whereas a new moon happens once a month. Here is further clarification: For this reason, astronomers have for years considered the possibility that hydrocarbon lakes and seas might exist on the surface of this misty moisty moon. The data derived from Cassini/Huygens validated this prediction. During its long and productive mission, now over, Cassini revealed that almost 2% of Titan's entire bizarre surface is coated wth gasoline-like liquids. The three little moons (Methone, Pallene, and Anthe) orbit at very similar distances from Saturn, and they have a dynamical relationship. Mimas disturbs the trio of little moons, and causes the orbit of Methone to vary by as much as 20 kilometers (12.4 miles). Mimas causes the orbit of Pallene to vary by a slightly smaller amount--but it has the greatest influence on the orbit of the moon Anthe.
