What is this small "circle" called and how can i move it into the middle of an object?

Getting Started

I try to rotate this colorful object “SmallCircle”. Instead of rotating like a wheel, it seems to rotate around that transparent little circle.
Other Objects like Camera or Player have this transparent little circle in the middle, except my SmallCircle. That might be the problem?!

I hope you understand my issue (English is not my first language, sry :)).

I still didn’t find the solution. My only option is to get away from unity for few days, because these simple yet unsolvable problems are giving me headaches :confused:

Look up parent / child relationships and how an offset child can be in a dramatically different place if you rotate the parent?

Or perhaps I didn’t understand your problem.
