EZ Aquarii is a triple star system 11.1 light-years from the Sun in the constellation Aquarius within the Milky Way. It is also known as Luyten 789-6, Gliese 866 and LHS 68. It is a variable star showing flares as well as smaller brightness changes due to rotation. The aggregate mass of the system is 0.3262±0.0018 solar masses. All three seem to have masses close to the hydrogen burning mass limit.
Delta Apodis is the Bayer designation for a double star in the southern constellation of Apus.
83 Aquarii is a binary star system in the equatorial constellation of Aquarius. The combined apparent visual magnitude of the pair is 5.43, which is faintly visible to the naked eye. Based upon an annual parallax shift of 15.57 milliarcseconds, it is located at a distance of around 209 light-years from Earth.

1 Vulpeculae is a class B4IV star in the constellation Vulpecula. Its apparent magnitude is 4.77 and it is approximately 780 light years away based on parallax.
32 Cygni is a binary star system in the Cygnus constellation. It is a 4th magnitude star, which can be seen with the naked eye under suitably dark skies. Parallax measurements give an estimated distance of 1,000 light-years (307 parsecs) from the Earth. However, Schröder et al. (2007) suggest the actual value, after correcting for Malmquist bias, may be closer to 1,174 light-years (360 parsecs). Although it is a spectrsocopic binary with components that cannot be separated visually, it has two entries in the Henry Draper Catalogue, with identical magnitudes and positions, but showing the spectral types of the two components.
41 Lyncis, also designated HD 81688 and named Intercrus, is a fifth-magnitude star located in the northern constellation of Ursa Major. An extrasolar planet is thought to be orbiting the star.
LN Andromedae, also known as HD 217811, HR 8768, is a formerly suspected variable star in the constellation Andromeda. Located approximately 458 parsecs (1,490 ly) away from Earth, it shines with an apparent visual magnitude 6.41, thus it can be seen by the naked eye under very favourable conditions. Its spectral classification is B2V, meaning that it's a hot main sequence star, emitting light approximately with a blackbody spectrum at an effective temperature of 18,090 K.
Catalog of 5,268 Standard Stars Based on the Normal System N30 is the 1952 auxiliary star catalogue created by Herbert Rollo Morgan to address proper motion inaccuracies in 19th century observations by converting contemporary catalogues from a mean epoch around 1900 to epoch and equinox 1950.0. However, the positions were derived from more than 70 recent catalogs with epochs of observation between 1917 and 1949. The N30 system is independent from any other astrometric system. Independent proper motions were determined by comparing the 1930 normal positions with the normal positions at the mean epoch, 30 years earlier, in the Albany General Catalogue, corrected by Morgan in 1948. Its primary use is the incorporation of 19th century astronomical data into modern research, and includes Harvard photometric magnitude, Henry Draper (HD) spectral type, and proper motion.
Gliese 208 is a red dwarf star with an apparent magnitude of 8.9. It is 37 light years away in the constellation of Orion. It is an extremely wide binary with 2MASS J0536+1117, an M4 star 2.6 arcminutes away

This object is visible to the naked eye as a faint, blue-white hued star with a baseline apparent visual magnitude of 5.00. It is receding from the Earth with a heliocentric radial velocity of +25 km/s.
16 Persei is a single, suspected variable star in the northern constellation of Perseus, located approximately 121 light years away based on parallax. It is visible to the naked eye as a yellow-white hued star with an apparent visual magnitude of 4.22. This object is moving further from the Earth with a heliocentric radial velocity of +14 km/s. It displays a relatively high proper motion, traversing the celestial sphere at the rate of 0.224″ per year.
ι Phoenicis, Latinized as Iota Phoenicis, is a binary star system in the southern constellation of Phoenix, near the constellation border with Grus. It is visible to the naked eye as a faint, white-hued star with an apparent visual magnitude that fluctuates around 4.71. This system lies approximately 254 light years from the Sun based on parallax, and it is drifting further away with a radial velocity of +19.4 km/s.
