What’s the difference between a rocket and a missile ?

The nomenclature can be confusing sometimes, but generally the word “rocket” is used in a military context to refer to relatively inexpensive unguided weapons powered by solid-fuel motors, while “missile” is generally shorthand for “guided missiles,” more expensive and complicated weapons that use movable fins to steer themselves to their targets and can fly much farther.
