Planet:Eclipso

Eclipso is one of the moons of the large gas giant in its home system, and orbits the giant so slowly that it rotates almost at the same speed that the plant itself orbits the system's sun. This causes the world to always be on the side opposite the sun, enabling a perpetual night. If it were not for its harboring life and this amazingly slow rotational period, it would be considered not interesting enough to warrant attention. It has been said that there should be a period of perpetual daylight due to it moving at a slightly different speed than the planet orbits at, although calculations as to how long it takes for them to occur and then how long they then last are vague, at best. Some scientists seem to speculate that this occurs once every 4,000 years, while others instead speculate that it's actually every 15,000 years, with numerous others believing that it is in between these two numbers.

Trivia

 * This planet was created at some point during my tenure as a High School student, and was therefore created sometime between 1999 and 2001.
