The people on the wandering earth took the earth to escape the solar system. What about the moon?

Answer 1

In the novel Wandering Earth, the moon was temporarily abandoned on Earth during the process of people taking the Earth away from the solar system. However, the moon was not completely abandoned because scientists believed that if the moon was not reused, it might float alone in interstellar space and eventually disappear into the darkness of the universe. Therefore, in the novel, the moon was used to provide some additional energy and resources to support the continued navigation of the earth and humans.
