A Closed and Common Orbit is a 2016 science fiction novel by Becky Chambers, published by Hodder and Stoughton.

In the aftermath of the events in The Long Way to a Small, Angry Planet, Lovelace the artificial intelligence illegally loads herself into an android body and leaves the starship Wayfarer to pursue an independent existence in the company of Pepper, a technician.

A parallel narrative strand explores the early years in the life of a genetically modified child slave.

[1] At The Guardian, Adam Roberts noted that, although the novel is a sequel, it "works as a standalone story"; he also observed that it shares the first book's strengths (including "complex characters" and "sheer likability") and weaknesses (including "a tendency for characters to pootle about rather than move the larger plot forward").

[2] Publishers Weekly called it "worthy", with a "friendly, soothing atmosphere" and "beautiful pacing and structure".
