* ''Manga/TwilightStarSuiAndNeri'': Due to CasualInterstellarTravel (Class-3 type) being commonplace, most if not all planets have been colonized and have been inhabited by most people from Earth, including Planet [=P53=]. The radio broadcast in Chapter 1 immediately affirms that another planet, [=104M=], would be in the process of colonization within another month and with [=D93=] expecting 30,000 people within November; as a consequence, Earth's population has decreased to a 3%, verging into becoming a [[InsignificantLittleBluePlanet footnote]] in the history books.

* ''Anime/VoltesV'': The Boazanian Empire, led by Emperor Zambajil, conquers planets left and right because their economic stability is derived from slaves. While they have already siezed numerous planets by the time the story begins, they set their sights on Earth because the human race are heavily reminiscient of Hornless Boazanians, their SlaveRace.

* ''Franchise/{{Gundam}}'' series usually have large space station-type colonies orbiting Earth, and cities on the Moon are pretty common. The Universal Century continuity also has the Axis colony, that was initially in the Asteroid Belt, and settlements near Jupiter that play a role in later installments. A few series also have settlements at Mars, either on a terraformed surface or just more orbiting space colonies, and at least one series included a giant space colony near Venus.
** The Universal Century featured Lagrange Point colonies and cities on The Moon. The sidestory ''F90'' featured a base on Mars (granted, it was a [[Main/TheRemnant Neo-Zeon]] base, that was destroyed at the end of the story), and ''[[Manga/MobileSuitCrossboneGundam Crossbone]]'' reveals that the Jovian System has been settled.

* ''Franchise/MassEffect'' subverts this somewhat, as the discovery of [[FasterThanLightTravel FTL travel]] very early in their spacefaring history resulted in the Sol system being mostly forgotten as humanity began expanding beyond the Mass Relay. This is because humans decided that expanding to other worlds beyond the Relay would be easier than taking the time to develop the worlds in Sol. The solar system mostly contains simple research, mining, or utility stations that at most only have populations of a couple hundred. Even Mars, which had a booming population prior to the discovery of the Prothean Archives and is implied to have been on the verge of being [[{{Terraform}} terraformed for greater habitability]], was turned into a forgotten backwater after the Archives were discovered. The largest non-Earth population is on the moon, but even then, there are only a couple of small cities whose combined population is only a few hundred thousand, compared to all of the extrasolar colonies, which have populations in the millions.

* In ''VideoGame/SierraOps'', Mars has been colonized for three hundred years, and 14% of humanity lives on space colonies located at Earth’s Lagrange points. There’s also Mondshire, a city on the surface of the Moon, and the game begins on a space station orbiting Venus.
