A triple star system consists of three gravitationally bound stars. The stars are in orbits around a common center of mass, usually so that two of the stars form a close binary star and the third is further away. This configuration is often called a hierarchical triple star. Multiple stars containing more than three stars can usually be decomposed to binaries and single stars that are in a hierachically bound system.

This article covers the physics of gravitation. ... The Pleiades star cluster A star is any massive gaseous body in outer space, just like the Sun. ... In physics, an orbit is the path that an object makes, around another object, whilst under the influence of a source of centripetal force, such as gravity. ... The center of mass or center of inertia of an object is a point at which the objects mass can be assumed, for many purposes, to be concentrated. ... A binary star system consists of two stars both orbiting around their barycenter. ...
These systems are also referred to as trinary stars, or ternary star systems.

In a triplestarsystem, each starorbits the center of mass of the system, usually so that two of the stars form a close binary star and the third is further away.
The system is composed of a yellow dwarf, an orange dwarf, and a red dwarf.
Polaris, the north star, is a triplestarsystem in which the closer companion star is extremely close to the main star---so close that it was only known from its gravitational tug on Polaris A until it was photographed by the Hubble Space Telescope in 2006.
HD 188753 is a triplestarsystem approximately 149 light-years away in the constellation Cygnus.
This starsystem is only the second triple-star system known to have a planet orbiting it [4], HD 188753 Ab, which was discovered in 2005 by Polish astronomer Dr. Maciej Konacki.
The primary star (HD 188753 A) is a 1.06 solar mass G-type (yellow dwarf).
