Neptune is the newly designated last “planet” in the solar system. It is the fourth gas giant and like Jupiter, it has its own “Great Red Spot” only in the case of Neptune it has been referred to as the “Great Dark Spot”. Like the other giants it also has a tenuous ring system and a system of moons. Only one of those moons, Triton, stands apart in size and characteristics and is one of the more interesting places to see in the solar system.
