Stationary.
Change of position relative to another object
velocity
Inertia
Collided Into would be with a stationary object while "with" would be with another moving object.
an object will keep moving in a particular direction unless another force acts on the object
Satellite

Change of position relative to another object
The object does not appear to be staying in one place. Or, it is moving if it's distance from another object is changing.
a "body" "moving body" an "object" is moving with constant velocity. [OR] a "body" is moving with constant velocity.
orbiting
Change of position relative to another object
velocity
revolution is an object moving in a pattern around another object.
If it isn't moving, the object is static.
Newton's First Law states that an object that is moving has the tendency to continue moving at the same speed; if it is at rest, the tendency is for the object to remain at rest. This law is also known as the law of inertia.
