The circle $C_2$ can be referred to as the stator of the epicycloid.

Note on Terminology
The term stator as used in this context appears to be non-standard.

The term has been taken by from the children's toy, which itself was taken from the term  as applied to the static part of a a rotary machine.

While the literature on epicycloids is extensive, there appears from some cursory web searching that there does not appear to be a standard name for either of the circles involved in their generation.

As the philosophy of values brevity, it has been decided that this can be remedied.
