In the start and ending of Cloud Atlas, Zachry (Tom Hanks) is shown on another planet, which has two moons and from which the Earth can be seen.
Is there any canonical identity given to this planet? Terraformed Mars would be a decent option, but the moons do not match Phobos and Deimos in size.
It doesn't appear to have a canonical name, Wikipedia identifies the location as an off world colony and the cited links for the below quote name every location except the location used in the epilogue:
A seventh time period, several decades after the events on Big Island, is featured in the film's prologue and epilogue: Zachry is revealed to have been telling these stories to his grandchildren on a beach near a city on an extraterrestrial Earth colony. The epilogue also confirms that Meronym succeeded in sending the message and traveled to the off-world colony where she lives with Zachry.
This text is basically mirrored on the Cloud Atlas Wikia.
