`Ternary` (or `trinary`) stars are not the same as `triple` stars. So, what is the basic underlying difference between these two? What are some popular examples of these two varieties?

Exactly the difference between **binary** and **double** stars.

## Trinary System

Three stars gravitationally bound to each other.

[Here](http://en.wikipedia.org/wiki/Star_system#Trinary) are some examples

## Triple Star System

Three stars that appear to be together but any one of them is gravitationally unbound.
