According to Newton's first law of motion, a body at rest or in motion with a constant velocity will remain in that state unless acted upon by a net external force. Therefore, if a body is moving at a constant velocity in outer space, it must be experiencing no net external force. Hence the net force required to move a body at a constant velocity in outer space is zero.
