If there are alien spaceships with cloaking device observing us within Earth's orbit, how can we detect them?

Humas could detect the existence of what could be earth-like far, far away planets by measuring the light it reflects from its parent star. If we could discover “rocks” light years away, surely we could monitor the near space around Earth for alien perverts, err, observers, can’t we? : )
