Local Sphere

The Local Sphere (also known as the Local Interstellar Neighbourhood) refers to the region of stars surrounding Sol in a 20 lightyear radius. There are roughly over a 150 celestial objects within the Local Sphere, white dwarfs and brown dwarfs included.

It is the main interstellar location of Humanity, with many of its systems colonised/or explored an is where most major colonies such as Anubis, Vesta and Providence etc are located an is consiered Humanity's rightful home in the Milky Way.

A handful of other sapient species also reside in this region such as the Tar'tha, who inhbait the planet of Ta'chipal 13 lightyears away. The Tar'tha colonise a lot of the Local Sphere's brown dwarf systems ue to their preference for dimmer light.

Two other races, the Vernha and the Jalisk (although not native to the Local Sphere) also possess some colonies in this region and often interact with the Tar'tha due to their similar biochemistries. Their interaction with Humans is often minimal as our biochemistries are too different, though they sometimes trade with us as some of their resources are highly valuable.

Alpha Centauri	4.3 Ly	3	Helion and Terminus	Binary system of a G-type and K-type main sequence star.
Barnard's Star	5.3	1	Nodens	Small red dwarf star, orbited by a titan world with exotic uncellular life
Adranus system (Luhman 16)	6.5	17
Viatorem (WISE 0855-0714)	7.26	418 moons		A Sub-brown dwarf mined for its natural supply of Tritium (Helium-3) and main headquaters of Tritium Incoprated.
Wolf 359	7.85 Ly	9
Lalande 21185	8.3	10
Sirius	8.6	3	Anubis	Brightest star in Earth's night sky and home to one of the closest major colonies. A dyson swarm exist around Sirius B which was the first built around an extrasolar star.
Luyten 726-8	8.7	0	None
Ross 154	9.7	9	None	Its sixth planet, a Neptunian ice giant, was found to have unicellular life in its atmosphere.
Markwell's Star	9.21	5	Luma	A low mass red dwarf, orbite by 5 planets and first system claimed by the Markwell Mining corporation.
Ross 248 (HH Andromedae)	10	6	Elmore	A red dwarf star orbited by 6 planets and location of the second extrasolar dyson swarm.
Epsilon Eridani	10.44	4	AEgir	A young K-type star, orbited by 4 planets which are Ragnarok, Thor, AEgir and Tyr. One of AEgir's moons, Bara, is home to unicellular life in its seas.
Lalande 9352	10.72
Ross 128	11	1	Ross 128 b
EZ Aquarii	11.1
61 Cygni	11.4	9	Vesta	A major system, consisting of two K-type stars and nine planets. It is the location of Vesta, a prominent colony within the region thanks to its close distance to Sol and other systems.
Apollyon	11.40	5		A dim, low mass red dwarf, discovered uring the mid 21st Century, which is rather odd given its close proximity to Sol. Despite being classed as a red dwarf, it is much more akin to a brown dwarf, with its first planet, Lucifer, a gas giant, being larger than the star itself. The system is home to several anomalies, check this article for more info.
Procyon	11.40	0	None	Briefly visited during the Interstellar Exploration Program, the system is a binary made up of a white main sequence star and a faint white dwarf. There are no planets in this system and thus, remains untouched to this day.
Struve 2398	11.48
Groombridge 34	11.61	1
DX Cancri	11.67
Tau Ceti	11.75	5	Elysia	A G-type star, orbited by five planets. It's fifth world, the gas giant Lethe, is home to Elysia, a terra-class moon that serves as an agricultural colony.
Epsilon Indi	11.86
Gliese 1061	11.98	3
YZ Ceti	12.12	3	None	An active red dwarf star, prone to frequent flares. variety. It is for this reason that no attempts to explore the system have been made. At least 3 earth-sized planets orbit around this star, however none of them are habitable nor inhabited.

Van Maanen's Star	14.2	8	Charybdis	Interest in this system was sparked during the late 21st Century, with the discovery of a planetary system around it. The sixth planet, Charybdis, gained the most attention, due to being a large, ringed ocean world, with a blazing hot temperature of around 275 C.
