North Korea launched a satellite today. Why do some people say that they are testing missiles, while others say that they are launching rockets?

People often say that launching a satellite means sending it into space with a rocket.

Rocket+satellite, the total height is tens of meters high, the top is satellite, about 2 or 3 meters high, and the rest are rockets.

Replacing a satellite with an explosive warhead, launching it into space, then re-entering the atmosphere and exploding at its destination is a strategic missile.

Let's make a simple metaphor:

Trains, buses, trucks-an empty "train" is like a rocket, which can carry people and goods, so "man" is a satellite and "truck" (train+goods) is a missile.

Hehe, this metaphor is a bit funny.
