Cave
A cave or cavern is a hollow place in the ground, especially a natural underground space large enough for a human to enter. Caves form naturally by the weathering of rock and often extend deep underground. The word cave can also refer to much smaller openings such as sea caves, rock shelters, and grottos.
Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called caving, potholing, or spelunking.
Types and formation
The formation and development of caves is known as speleogenesis. Caves are formed by various geologic processes and can be variable sizes. These may involve a combination of chemical processes, erosion from water, tectonic forces, microorganisms, pressure, and atmospheric influences.
It is estimated that the maximum depth of a cave cannot be more than 3,000 metres (9,800 ft) due to the pressure of overlying rocks. For karst caves the maximum depth is determined on the basis of the lower limit of karst forming processes, coinciding with the base of the soluble carbonate rocks.
The Cave (video game)
The Cave is a puzzle-platform/adventure video game developed by Double Fine Productions and published by Sega in January 2013 on the PlayStation Network, Nintendo eShop and Xbox Live Arcade storefronts via the PlayStation 3, Wii U and Xbox 360 consoles and on Steam for Microsoft Windows, OS X and Linux. It was later released on October 3, 2013 on iOS devices, and on December 2, 2013 on the Ouya.
The game was created by Ron Gilbert, building on an idea that he has had for nearly twenty years about a cave that lures people into it to explore their darker personality traits. The game is rated "teen" for blood and violence. The game borrows concepts from his earlier 1987 game, Maniac Mansion, in which the player initially selects three different characters from a cast of seven to explore the Cave. Many of the game's puzzles require the three characters to work in coordination to complete, while some puzzles are specific to the unique abilities of a character; in this manner the Cave can only be fully explored through multiple play-throughs.

Natural satellite
A natural satellite is a celestial body that orbits another celestial body of greater mass (e.g., a planet, star, or dwarf planet), which is called its primary. For example, the Moon is a natural satellite of Earth, and Earth is a natural satellite of the Sun.
In the Solar System there are 173 known natural satellites which orbit within 6 planetary satellite systems. In addition, several other objects are known to have satellites, including three IAU-listed dwarf planets: Pluto, Haumea, and Eris.As of January 2012, over 200 minor-planet moons have been discovered. There are 76 known objects in the asteroid belt with satellites (five with two each), four Jupiter trojans, 39 near-Earth objects (two with two satellites each), and 14 Mars-crossers. There are also 84 known natural satellites of trans-Neptunian objects. Some 150 additional small bodies have been observed within the rings of Saturn, but only a few were tracked long enough to establish orbits. Planets around other stars are likely to have satellites as well, and although numerous candidates have been detected to date, none have yet been confirmed.
13 Moons
13 Moons is a 2002 comedy-drama film by director Alexandre Rockwell. The title is a reference to the saying of a minor character's mother, who suggested that if nights of the full moon are strange, then "this must be the night of thirteen moons."
Plot
The film opens with a clown (Buscemi) whose wife (Beals) and stripper girlfriend (Parsons) just discovered each other's existence. When his wife is jailed for trying to run him over, the stripper, the clown and his partner (Dinklage) contact a bail bondsman (Proval) whose wife just left their sickly son Timmy (Wolff) in his care. On the way, they are accosted by a crazed drug addict named Slovo (Stormare) who is hit by a car soon after.
At the jail, the five meet up with an angry record producer (Mitchell) and the girlfriend he believes to be pregnant (Rollins) whom he plans to make a star, despite her protestations of not having any talent. Also along for the ride are two priests (Vince and Williams), one of whom has begun to doubt the wisdom of the Roman Catholic Church, and who are trailing to bail out a third priest (Messina) who was goaded into a fight by the proprietor of a strip club (Rockwell).
