The invention relates to the technical field of spacecraft rendezvous guidance, and particularly relates to a remote guidance method and remote guidance device for a spacecraft and a rendezvous part. The method comprises the steps: obtaining the motion state of the spacecraft in a flight process, and enabling the spacecraft to sail along a preset orbit; acquiring the position and the speed of the rendezvous part on the ground, transmitting the position and the speed of the rendezvous part to the spacecraft, and determining the relative distance between the spacecraft and the rendezvous part; if the relative distance exceeds a preset distance threshold value, performing static planning of a model based on the motion state of the spacecraft so as to determine that the spacecraft enters an autonomous guidance range of the rendezvous part; and if the spacecraft enters the autonomous range, triggering the spacecraft to perform autonomous guidance towards the rendezvous part.
