Earth

Earth, sometimes Terra (or "Sol III" to the truly insufferable), is the homeworld of both humans and cetaceans and the capital world of the United Federation of Planets. Most Federation government offices are located in the historic city of Paris on the European continent, while both Starfleet Headquarters and Starfleet Academy are located in the city of San Francisco in North America. Devastated by a conflict called "World War Three" in the mid-21st century, the population has since rebounded to almost 8 billion humans and 4.6 million cetaceans, joined by perhaps 900 million immigrants of other species.

Although Earth has always kept close ties with Mars and Luna, it retains a distinct culture that highly values preservation and restoration of its shattered history that off-worlders find to border on the obnoxious. The Ferghana Valley is considered an especially precious cultural treasure, being one of the few places in Asia to remain mostly undamaged by the global conflict raging around it. Hundreds of thousands of tourists filter through Tashkent Starport every day on their way to tour through nearly 3000 years of human history. Afterwards, they can take a shuttle or transporter straight to Bozeman to see the rest, from the landing site of the T'Plana Hath to the converted missile silo where the Phoenix was built from scraps.

Sadly, some culturally pivotal sites like Jerusalem, Beijing, and Washington are too far gone to ever be properly restored, but damned if the humans aren't happy to offer you all the AR holo-tours you can stomach.

Earth still possesses a rather large industrial sector, although much of it has been relocated to orbital platforms. One particularly significant complex includes more than five dozen orbitals stretching between San Francisco and the former city of Vancouver, including a major Starfleet shipyard. The largest orbital by far is the gargantuan Starbase 1, universally known as Spacedock. Home to upwards of 70,000 individuals and the galaxy-famous Starfleet Museum, the mushroom-shaped station is essentially a city in its own right, containing widespread civilian amenities and even a club soccer team that plays on the third level of Earth's football pyramid.
