The Veridian system

"Solar System" redirects here. For the star system in which the planet Earth is located, see Sol system.

A star system or solar system is the area around a star (or a group of stars) which contains all of the planets, moons, asteroids, nebulae and other landmarks which are held in place by the star's gravity well.

A Solar system's boundaries are usually marked by the area in which a star or celestial body's gravitational force affects its surrounding environment. Often the edge of these boundaries is a large, thin layer of ice, dust and debris called an Oort cloud.

The planets and other bodies in a solar system orbit the star (or stars) at different distances; these distances can be classified into three distinct zones: (1) the hot zone, which is closest to the star, produces temperatures prohibitive of life, such as on Mercury; (2) the ecosphere zone, where life can find a foothold and flourish, given the balance between solar energy received and radiated, such as Earth, Vulcan, and Bajor; and (3) the cold zone, which lies farthest from the star and receives the least energy; Pluto orbits in the cold zone, where Sol appears merely as another bright star.

Using warp drive to travel from within a solar system to another point in the system is not recommended. The USS Defiant performed such a maneuver in 2373 in the Bajoran system. (Star Trek: The Motion Picture; DS9: "By Inferno's Light")

In 2254, Spock compared the Talos star group to the Earth solar system. (TOS: "The Cage")

Although many star systems have been described in detail in Star Trek, additional information for this article has been derived from real-life scientific knowledge.
