What is a Rocket?
A rocket is spacecraft, aircraft or other vehicle which obtains thrust by ejecting a jet of fast moving fluid exhaust from a rocket engine. Chemical rockets create their exhaust by the combustion of rocket propellant. ...
They are normally used for carrying satellites into space.
What is a missile?
A rocket carrying a warhead of conventional or nuclear explosives; may be ballistic or directed by remote control projectile.
or
A weapon that is forcibly thrown or projected at a targets.
Difference between Missile & Rocket
A missile is any weapon which flies toward its target, it could be anything from a rock that you pick up off the ground and throw at an enemy, to a spear, an arrow, a bullet, up to a multi-staged rocket carrying multiple MIRV-type nuclear weapons.
Where as,a rocket is simply a non-air-breathing object which is propelled by shooting a stream of gases out behind it.
Guided Missile
Guided Missiles, usually containing conventional or nuclear explosives, guided in flight towards a target either by remote control or by internal mechanisms. Guided missiles vary widely in size and type, ranging from large strategic ballistic missiles with nuclear warheads to small, portable rockets carried by foot soldiers.

POWER SOURCE
SELF CONTAINED ROCKET MOTORS: It contains a motor fan which force it by the air to proceed. It is less efficient & used in the past era.
2) AIR BREATHING JET ENGINE’S: In this type of power source the combustion chamber in which the fuel burns is called the motor When the fuel in a solid-propellant rocket is ignited, the gases formed during combustion are forced out the nozzle and the rocket moves forward. The fuel is called the grain and is often formed with a hollow core for longer burning times.
WARHEAD
A warhead is an explosive device used in military conflicts to destroy enemy vehicles or buildings.
Typically, a warhead is delivered by a missile,rocket or torpedo. It consists of the explosive material, and a detonator.
Types of warhead
Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a shockwave.
Chemical: A toxic chemical, such as nerve gas is dispersed, which is designed to injure or kill human beings.
Biological: An infectious agent, such as anthrax is dispersed, which is designed to sicken and kill humans

Guidance system
A guidance system is a device or group of devices used to navigate a ship, aircraft, missile, rocket, satellite, or other craft. Typically this refers to a system that navigates without direct or continuous human control. Systems that are intended to have a high degree of human interaction are usually referred to as a navigational system
TYPES OF GUIDANCE
REMOTE CONTROL
BEAM RIDING
ACTIVE RADAR HOMING
WIRE GUIDED MISSILE
INFRARED HOMING
REMOTE CONTROL
IN THIS TYPE OF GUIDANCE SYSTEM WE SIMPLY USED A REMOTE CONTROL TO JUST GIVE THE INSTRUCTION TO THE FINS OF THE MISSILE TO MOVE IT TOWARD’ THE TARGET
BEAM RIDING
Beam-riding guidance leads a missile to its target by means of radar or a laser beam. It is one of the simplest forms of radar or laser guidance.
The main use of this kind of system is to destroy airplanes or tanks
ACTIVE RADAR HOMING
Active radar homing is a type of missile guidance where a guided missile contains a radar transceiver and the electronics necessary for it to find and track its target autonomously.
WIRE-GUIDED MISSILE
A wire-guided missile is a missile guided by signals sent to it via thin wires reeled out during flight.
INFRARED HOMING
Infra-red homing refers to a guidance system which uses the infra-red light emissions of a target to track it. Missiles which use infra-red seeking are often referred to as "heat-seekers". Infra-red is just below the visible spectrum of light and is radiated mostly by hot bodies.

MAJOR ADVANCED GUIDANCE SYSTEMS
Global Positioning System (GPS)
Optical guidance
Global Positioning System (GPS)
This system of satellites provides extremely accurate position information. The receiver's position is triangulated using satellites in known orbits. Commercial receivers are limited in how accurately they may provide position data, as well as the maximum velocity at which they may operate. This is to prevent their use in manufacturing weapons.
Optical guidance
Guided missiles use stored images of the terrain they are to fly over and an external sensor to track their current position. This guidance system was extremely expensive and not suitable for use in small payload operations. These were used on cruise missiles before the advent of GPS, which is both cheaper and more accurate. Devices that implement optical guidance incur high costs because of the high on-board processing requirements needed to check the current location against the course data
ANTI SATELLITE MISSILE
Anti-satellite weapons (ASATs) are weapons designed to be used against artificial satellites.
ANTI-SHIP MISSILE
An Anti-ship missile (AShM) is a military missile designed for use against naval surface ships.
ANTI-TANK MISSILE
An Anti-tank guided missile (ATGM) is a missile primarily designed to hit and destroy tanks. An alternative name is Anti-tank guided weapon (ATGW).
Advantages Missiles have a consistent and versatile damage output, and are capable of dealing single damage types. It is also impossible for a missile to miss a target, unless the target outruns the missile, moves out of range, or disengages and warps away.
Disadvantages
Missiles can be destroyed in flight either with Defender missiles or with a well-timed smartbomb detonation, partially or completely nullifying the attacker's damage output.
