 EZ Aquarii 3
EZ Aquarii may have been discovered by Willem Jacob Luyten (1899-1994), who found the proper motions of over 520,000 stars despite the loss of sight in one eye since 1925 by building an automated photographic plate scanner and measuring machine.
All three stars appear to be M-type red dwarfs near the hydrogen burning mass limit -- at least 75 Jupiter masses -- with an aggregate mass of about 34 percent of Sol's (Woitas et al, 2000; or Defosse et al, 1999).
As a result, the distance from star C where an Earth-type planet would be comfortable with liquid water is less than 0.006 AU, but such an orbit would likely be disrupted by the proximity of Star A. It is also known as Gl 866 C (RECONS) list of the 100 Nearest Star Systems).

 The Red Dwarf Kings
EZ Aquarii is a system of two red dwarfs separated by 1.2 Au distance, of which the A star is itself double.
After the Three Kings developed the system, the stars were observed to darken as if there was an extensive light gathering system in place, and the infrequent flares were replaced by steady coronal emissions in the visible wavelengths.
Early Federation attempts to colonise these three systems failed, two Han ships to EZ Aquarii and one Genetekker ship to Lacaille 9352 were caught by unusually large semi-coherent flares and destroyed, while a !Kung colony that established around Gl876 was mysteriously lost.

 CalendarHome.com - Aquarius - Calendar Encyclopedia
Two planetary nebulae are found in Aquarius: NGC 7009, called the Saturn Nebula due to its resemblance to the planet, to the southeast of η Aquarii; and NGC 7293, the famous Helix Nebula, southwest of δ Aquarii.
The best-known myth identifies Aquarius with Ganymede, a beautiful youth with whom Zeus fell in love, and whom he (in the guise of an eagle, represented as the constellation Aquila) carried off to Olympus to be cupbearer to the gods.
Aquarius generally resembles the figure of a man, and when considering fainter humanly visible stars, it takes on the image of a man with a bucket from which is pouring a stream.

 The milky way
The latest group of five young stars, found by Jessica Lu of the University of California in Los Angeles and her colleagues using the Keck I telescope in Hawaii, is moving in convoy even closer to the galactic centre - just 0.26 light years away.
The star is a metal-rich star, laden with heavy elements, which are prevalent toward the centre of the galaxy.
The star at the centre of this system is a pulsar named PSR B1257+12 -- the extremely dense and compact neutron star left over from a massive star that died in a violent explosion 1,500 light years away in the constellation Virgo.

 EZ Aquarii ABC System Orbits
Disrupted H.Z. This animation attempts to relate the orbits (and possible habitable zones) of Stars A, B, and C in the EZ Aquarii 3 system to their respective centers of mass.
The initial display shows the AC-B System's actual orbital tilt (at an inclination of 112.4°) from the visual perspective of an observer on Earth, Indeed, the orbital inclination of any planet that may be discovered someday in this star system would likely be different from those of the habitable zone orbits depicted here.
(For the purposes of this animation, the masses of Stars A, B, and C are assumed to be 0.13, 0.12, and 0.09 Solar, respectively.)

 Gliese 876 / Ross 780
The star is around 76 percent as enriched as Sol in elements heavier than hydrogen (Bean et al, 2006; and Ken Croswell, 2006).
Since this red dwarf star is so cool and dim, its habitable zone may be located at around one to two tenths -- 0.112 to 0.221 AU -- of the Earth-Sun distance (Jones and Sleep, 2003), given a bolometric luminosity around 0.124.
Furthermore, past analyses with infrared speckle interferometry indicated that the star does not have large companions between one and 10 AU of the star (Henry and McCarthy, 1990; and Leinert et al, 1997).

Surrounding these bright star "asterisms" are many dimmer stars that do not form part of the pattern.
As mentioned above, the ancients observed that the Sun, Moon and those 5 funny wandering stars (the planets known to the ancients) seem to be constrained to a particular region of the sky, never traveling really far north or south of a wide band of stars.
Since the stars seem "fixed" in space we need to give them their own coordinates (like latitude and longitude) but which are fixed to the stars, not the Earth.

If so, there are many near-Earth stars that wouldnt need a multigenerational ship...if your ship is fusion-powered (fusion utilized as both energy source as well as propulsion), then you can reach a lot of near-Earth stars in a single generation.
If they surveyed the system already and found a habitable planet, it would be just plausible that they would send a mission designed to land the population on the planet and leave a minimal orbital capability, or that a dire emergency forced them to land on the planet.
But if they've had time to try terraforming an uninhabitable rock in one star system, then travel to another system, they had to be self-sustaining for a generation already.

After which we visit the dim red EZ Aquarii trio, Lacaille 9352, the largest local red star, (but still a dwarf), Epsilon Indi, a small orange star, another pair of larger red dwarfs known as Groombridge 34 A and B. Tau Ceti, a yellow star like our Sun except much smaller.
And we can't head that direction without seeing Spocks home system Epsilon Eridani, the star in which Vulcun is supposed to revolve, and in fact a planet or 2 has been discovered there.

Lacaille 9352 (Lac 9352) is a red dwarf approximately 3.52 pc or 11.47 light years from Earth's Solar System.
This star has the fourth highest known proper motion, moving a total of 6.9" per year.
(This is still a very small movement overall, however, as there are 3,600" in a degree of arc.) Its closest neighbour is the EZ Aquarii Star System, 1.29 pc or 4.21 ly away.
