79 Ceti, also known as HD 16141, is a binary star system located 123 light-years from the Sun in the southern constellation of Cetus. It has an apparent visual magnitude of +6.83, which puts it below the normal limit for visibility with the average naked eye. The star is drifting closer to the Earth with a heliocentric radial velocity of −51 km/s.
HD 88133 is an 8th magnitude star in the constellation of Leo. It is classified as a yellow main sequence star. It is slightly more massive than the Sun, cooler and more luminous. Located at a distance of 241 light years from Earth it is not in our immediate neighbourhood and thus not visible to the unaided eye. With a small telescope it should be easily visible.
HD 4208 is a star in the southern constellation of Sculptor. It has a yellow hue with an apparent visual magnitude of 7.78, making it too dim to be visible to the naked eye. But with binoculars or small telescope it should be an easy target. This object is located at a distance of 111.6 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +57 km/s.
HD 40979 is a triple star system in the northern constellation of Auriga. The combined brightness of this group lies below the typical limit of visibility to the naked eye at an apparent visual magnitude of 6.74. It is located at a distance of approximately 108 light years from the Sun based on parallax. The system is receding with a radial velocity of +32 km/s. It has a relatively high rate of proper motion, traversing the celestial sphere at the rate of 0.182″ per year.

HD 231701 is a yellow-white hued star in the northern constellation of Sagitta, near the southern constellation border with Aquila. With an apparent visual magnitude of 8.97, it is too dim to be viewed with the naked eye, but can be seen with powerful binoculars or a small telescope. Parallax measurements provide a distance estimate of approximately 356 light years from the Sun, but it is drifting closer with a radial velocity of −63 km/s. It is predicted to come as close as 189.5 light-years in 1.345 million years.
HD 8574 is a single star in the equatorial constellation of Pisces. It can be viewed with binoculars or a telescope, but not with the naked eye having a low apparent visual magnitude of +7.12. The distance to this object is 146 light years based on parallax, and it has an absolute magnitude of 3.88. The star is drifting further away from the Sun with a radial velocity of +18 km/s. It has a relatively high proper motion, advancing across the celestial sphere at the rate of 0.298 arc seconds per annum.
HD 37605 is a star in the equatorial constellation of Orion. It is orange in hue but is too faint to be visible to the naked eye, having an apparent visual magnitude of 8.67. Parallax measurements yield a distance estimate of 153 light years from the Sun. It has a high proper motion and is drifting closer with a radial velocity of −22 km/s.
HD 118203 is a star located in the northern circumpolar constellation of Ursa Major. It has the proper name Liesma, which means flame, and it is the name of a character from the Latvian poem Staburags un Liesma.

HD 178911 is a triple star system with an exoplanetary companion in the northern constellation of Lyra. With a combined apparent visual magnitude of 6.70, it is a challenge to view with the naked eye. The system is located at a distance of approximately 161 light years from the Sun based on parallax measurements, but is drifting closer with a radial velocity of −38 km/s.
HD 179791 is suspected variable star in the equatorial constellation of Aquila. It is a challenge to see with the naked eye even under good viewing conditions, having an apparent visual magnitude of 6.48. The distance to HD 179791 can be estimated from its annual parallax shift of 5.3 mas, which yields a value of 616 light years. It is moving further from the Earth with a heliocentric radial velocity of +16 km/s. Astrometric measurements of the star show changes in motion that may indicate it is a member of a close binary system.
HD 87883 is star in the northern constellation of Leo Minor. It is too faint to be viewed with the naked eye, having an apparent visual magnitude of 7.56. The star is located at a distance of 59.7 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +9.3 km/s. It has an absolute magnitude of 6.27.
29 Camelopardalis is a double star in the circumpolar constellation Camelopardalis. With an apparent magnitude of 6.59, it's right below the max visibility to the naked eye, and can only be viewed under phenomenal conditions. The star is located 484 light years away based on parallax, but is drifting further away with a radial velocity of 3.9 km/s.
11 Cephei is a single star in the northern constellation of Cepheus, located 184 light years away from the Sun. It is visible to the naked eye as a faint, orange-hued star with an apparent visual magnitude of 4.55. The star has a relatively high proper motion, traversing the celestial sphere at the rate of 0.153 arc seconds per annum. It is moving closer to the Earth with a heliocentric radial velocity of −38 km/s.
17 Crateris is a wide binary star system in the equatorial constellation of Hydra, located 90.5 light years away from the Sun.

The system is traversing the celestial sphere with a relative proper motion of 24.9 mas/y, and is moving away from the Earth with a heliocentric radial velocity of +5.8 km/s.
34 Pegasi is a triple star system in the northern constellation of Pegasus. It has a yellow-white hue and is dimly visible to the naked eye with an apparent visual magnitude of 5.76. The system is located at a distance of 131 light years from the Sun based on parallax, but is drifting closer with a radial velocity of −13.5 km/s. It has been catalogued as a member of the Hyades Supercluster, although its membership status remains doubtful.
89 Leonis is a single star in the equatorial constellation of Leo, the lion. It has a yellow-white hue and is faintly visible to the naked eye with an apparent visual magnitude of 5.70. Based upon parallax measurements, it is located at a distance of 88 light years from the Sun. The star has a high proper motion and is moving further away with a radial velocity of +4.8 km/s. It is a candidate member of the TW Hydrae stellar kinematic group.
HD 221420 is a likely binary star system in the southern circumpolar constellation Octans. It has an apparent magnitude of 5.81, allowing it to be faintly seen with the naked eye.
