According to one embodiment, a tracking apparatus includes a spherical body, three or more spherical driving units, a hold unit, a control unit. The three or more spherical driving units are connected to the movable body and kept in contact with portions of the spherical body to move the movable body in a desired direction. The hold unit connects the third gimbal to the movable body, and holds the spherical driving units pressed against the spherical body. The control unit controls the spherical driving units to track the target, using the first to fourth rotation angles.
