Delta Aquarii, officially named Skat, is the third-brightest star in the constellation of Aquarius. The apparent visual magnitude is 3.3, which can be seen with the naked eye. The distance to this star is about 113 light-years based upon parallax measurements, and it has a close companion.
Epsilon Trianguli, Latinized from ε Trianguli, is a binary star system in the northern constellation of Triangulum. Based upon measurement of its trigonometric parallax, it is approximately 390 light years from Earth.
Psi3 Aquarii, Latinized from ψ3 Aquarii, is the Bayer designation for a visual binary star system in the constellation of Aquarius. It has an apparent visual magnitude of 4.98, which is bright enough to be seen with the naked eye. Parallax measurements give a distance estimate of roughly 262 light-years.
Lambda Arietis is the Bayer designation for a double star in the northern constellation of Aries. Based upon an annual parallax shift of 25.32 arcseconds, this system is approximately 129 light-years distant from Earth. The pair have a combined apparent visual magnitude of 4.79, which is bright enough to be viewed with the naked eye. Because the yellow secondary is nearly three magnitudes fainter than the white primary, they are a challenge to split with quality 7× binoculars and are readily resolvable at 10×.
Omicron Arietis, Latinised from ο Arietis, is the Bayer designation for a single, blue-white-hued star in the northern constellation of Aries. It has an apparent visual magnitude of +5.78, which means it is dimly visible to the naked eye. Based upon an annual parallax shift of 5.49 mas as seen from Earth, it is located roughly 590 light-years from the Sun. At that distance, the visual magnitude of the star is diminished by an extinction factor of 0.22 due to interstellar dust.
18 Aquarii is a single, yellow-white hued star in the equatorial constellation of Aquarius. The designation is from the catalogue of English astronomer John Flamsteed, first published in 1712. The star is faintly visible to the naked eye with an apparent visual magnitude of 5.49 and is located about 154 light-years from Earth.
52 Arietis is a triple star system in the northern constellation of Aries. 52 Arietis is the Flamsteed designation. The combined apparent magnitude is +5.46, which is bright enough to be faintly visible to the naked eye. Based upon an annual parallax shift of 6.05 mas, the system is roughly 540 light-years distant from the Earth. The inner pair of this system consist of two nearly identical B-type main sequence stars, each with about five times the mass of the Sun. The tertiary component is a smaller star with 88% of the Sun's mass, and is a common proper motion companion.
11 Arietis is a star in the northern constellation of Aries. 11 Arietis is the Flamsteed designation. It has an apparent visual magnitude of 6.01, which makes it a challenging target to view with the naked eye in suitably dark skies. Based upon an annual parallax shift of 3.72 mas, the distance to this star is approximately 880 light-years.
14 Aquilae is a probable spectroscopic binary star system in the equatorial constellation of Aquila. 14 Aquilae is the Flamsteed designation though it also bears the Bayer designation g Aquilae. It is visible to the naked eye as a dim, white-hued star with an apparent visual magnitude of 5.42, and it is located at a distance of approximately 500 light-years from Sun. The star is moving closer to the Earth with a heliocentric radial velocity of −39 km/s, and may come as close as 136 light-years in around 3.5 million years.
35 Aquilae is a star in the equatorial constellation of Aquila. 35 Aquilae is its Flamsteed designation though it also bears the Bayer designation c Aquilae. The apparent visual magnitude of this star is 5.8, which means it is a faint star but visible to the naked eye from dark suburban or rural skies. It has an annual parallax shift of 16.34 mas that is caused by the Earth's orbit around the Sun. This yields a distance estimate of 200 light-years, give or take a 4 light-year margin of error. At this distance, the visual magnitude is diminished by 0.26 from extinction caused by interstellar gas and dust.
68 Aquilae is a double star in the equatorial constellation of Aquila. 68 Aquilae is its Flamsteed designation. Its apparent magnitude is 6.12.
Rho2 Cephei, Latinized from ρ2 Cephei, or simply ρ Cephei, is a solitary star in the northern constellation of Cepheus. With an apparent visual magnitude of 5.50, it is faintly visible to the naked eye, forming an optical pair with Rho1 Cephei. Based upon an annual parallax shift of 13.31 mas as seen from the Earth, it is located about 245 light years from the Sun.
Gamma Camelopardalis, Latinized from γ Camelopardalis, is a suspected wide binary star system in the northern circumpolar constellation of Camelopardalis. With a visual magnitude of 4.66, it is faintly visible to the naked eye. Based upon an annual parallax shift of 9.09 mas as seen from Earth, this star is located about 359 light years from the Sun.
54 Ceti is an older Flamsteed designation for a star that is now located within the constellation boundaries of Aries, the Ram. In the present day it is known by star catalogue identifiers like HD 11257 or HR 534. At an apparent visual magnitude of 5.94, it can be seen with the naked eye. The distance to this star, as determined using parallax measurements made during the Hipparcos mission, is approximately 139 light-years, give or take a 6 light-year margin of error. It is located near the ecliptic and hence is subject to occasional occultation by the Moon.
Omega Aurigae, Latinized from ω Aurigae, is the Bayer designation for a double star in the northern constellation of Auriga. Its apparent magnitude is 4.95, which is bright enough to be seen with the naked eye. The distance to this system, as determined using parallax measurements, is approximately 162 light-years. The system is a member of the Columba group of co-moving stars.
16 Camelopardalis is a single star in the northern circumpolar constellation Camelopardalis, located 348 light years away from the Sun as determined from parallax measurements. It is visible to the naked eye as a faint, white-hued star with an apparent visual magnitude of 5.28. This object is moving further from the Earth with a heliocentric radial velocity of around 12 km/s.
HD 93905 is a solitary star located in the southern constellation Antlia. The star has an absolute magnitude of 0 and an apparent magnitude of 5.61, making it faintly visible to the naked eye under ideal conditions. The star is located 371 light years away based on its parallax shift and is drifting closer with a helocentric radial velocity of −9.6 km/s.
Alruba, a name derived from Arabic for "the foal", is a suspected astrometric binary star system in the northern circumpolar constellation of Draco. It is just barely visible to the naked eye as a dim point of light with an apparent visual magnitude of 5.76. Based on parallax measurements obtained during the Gaia mission, it is located at a distance of about 457 light-years from the Sun. The system is drifting closer with a radial velocity of −2 km/s.
HD 34868 is a solitary star located in the southern constellation Columba. With an apparent magnitude of 5.97, it's barely visible to the unaided eye. The star is located 410 light years away based on parallax, but is drifting away with a heliocentric radial velocity of 18 km/s.
HD 63584 is a solitary star in the southern circumpolar constellation Volans. With an apparent magnitude of 6.15, it is barely visible to the naked eye under ideal conditions. The star is located 420 light years away based on parallax, but is drifting away with a radial velocity of 10.4 km/s.
