when car moves with uniform velocity with respect earth`s surface ,then we define that car as inertial frame of reference.But is there any system exist with respect to which we can say earth is inertial frame of reference ? If exist then which is it ? or if not exist then how we can say earth as inertial frame of reference?

In universe there is no perfect inertial frame exist. actually earth is not a perfect inertial frame.The earth is a inertial frame of reference because we also rotating with respect to earth ans it doesn't accelerated that's why it rotating with respect to sun yet we consider it inertial frame of reference.because we know the inertial frame of reference is that reference which is rest on moving with constant velocity.
