The phrase usually used for this is "reference frame".
In theory, you can never truly detect if an object is in motion. Although I may travel in my car on the highway, I am not wrong to say that instead of myself moving across the earth, the earth is moving under me! Relativity proves to us that it is impossible to accurately show if an object is in motion or not. From a mathematical perspective, an object that you assume to be moving must be set relative to another object. This is in order to make accurate calculations about the object in question.

A landmark - or reference point.

It is a "reference point." On the street level, use a landmark, such as a statute, or a stationary object, such as a lamppost. Any motion detected is relative to what we perceive as stationary. However, we are hard pressed to say anything is truly at rest in the universe. For practicality, we can pick a distant star as an object "approximately" at rest. Since the star is many light-years away, any motion of the star can be deemed very small.
