This is a list of planets in the wormhole Nexus, from Aslund to Zoave Twilight.
Aslund was connected to the Hegen Hub, which was its only route to the rest of the galaxy. It was an impoverished, barely terraformed agricultural world.
A planet with an exclusively male society. The homeworld of Dr. Ethan Urquhart.
A planet with a feudal, military culture. Homeworld of Miles Naismith Vorkosigan.
One of the most scientifically advanced planets in the galaxy. Also, one of the most liberally tolerant and open, as well as egalitarian.
Highly advanced and heavily populated, Earth was not well situated in the nexus; in spite of its history and wealth, it did not play an important role in Nexus affairs. There were hints of catastrophic changes in its history, such as mutated animals and insects, and greatly elevated sea level.
A wealthy and advanced planet, Escobar was situated somewhere between Sergyar and Beta Colony. Various personal and place names suggest it was founded by a Latin culture. The Barrayaran Imperium attempted to invade Escobar with disastrous results.
Center of the eight-planet Cetagandan Empire.
A planet principally known for having untraceable documentation for people born in a certain time period roughly matching when it suffered a major tectonic catastrophe three years before Miles was born. (Mentioned in Brothers in Arms)
An obscure cul-de-sac planet. A pilot using Necklin color drive jump implants would become the color "red" while making the jump to this planet. (Mentioned in The Warrior's Apprentice)
A famous high-technology planet near Zoave Twilight.
A world without a government, it was a former pirate base turned into a slew of lawless corporate fiefdoms
Also known as New Hope II, it was an advanced world with a significant human population despite having an ice-age-like climate. The planet's capital city was Kitahashi/Northbridge. Its closest wormhole led to Escobar.
Formerly independent planet with many wormhole links, including the only existing gateway to Barrayar; later invaded and annexed by Barrayar. In the midst of a long terraforming project, the inhabitants lived in domes.
A planet that provided mercenary bodyguards (called Kshatryan Foreign Legion and Kshatryan Imperial Mercenaries) across the Nexus; it was very far from Barrayar. Mentions are in The Warrior's Apprentice and A Civil Campaign.
One of the Western Orion Arm group of planets.
A planet located somewhere between the Dagoola IV prison colony and Earth.
Occupied by the Cetagandan Empire, Marilac eventually regained its independence, thanks in part to covert Barrayaran aid.
Mentioned briefly in Brothers in Arms, it had pleasure domes.
Mentioned briefly in The Vor Game, its local wars featured the use of "trigonial strategy."
One of the eight satrapy planets of the Cetagandan Empire, it was adjacent to Vervain.
A relatively important planet in the Nexus that is never visited in any of the books of the Vorkosigan Saga. Orient Station was controlled by Orient IV.
Pol was a neighbor of the Barrayaran Empire; it served as a link between Komarr and the Hegen Hub.
A non-colonized planet near Orient IV.
The newest addition to the Barrayaran empire, it was a previously uninhabited planet with a link from Komarr to Escobar.
Tau Ceti Five was the hub of the Western Orion Arm group of planets; it served as Sector II headquarters for Barrayar.
Also known as Quaddiespace, this was not a planet but rather a collection of stations and hollowed-out asteroids.
Probably a planet that was not too far from Kline Station. Its sole mention is in Ethan of Athos, as a place where "Varusan crotch rot" originates.
Mentioned only briefly in The Warrior's Apprentice, some warfare involving Skya IV and Walshea was featured in Sri Simka's volumes of military history.
An obscure mostly-ocean planet that was very far from Barrayar.
A major Nexus crossroads, it lay just off from Vega Station; it was neutral with regard to its neighbor, the Cetagandan Empire.
