HD 80606 and HD 80607 are two stars comprising a binary star system. They are approximately 217 light-years away in the constellation of Ursa Major. Both stars orbit each other at an average distance of 1,200 astronomical units. The binary system is listed as Σ1341 in the Struve Catalogue of Double Stars; however, this designation is not in wide use and the system is usually referred to by the HD designations of its constituent stars. An extrasolar planet has been confirmed to orbit HD 80606 in a highly elliptical orbit.

Although given a variable star designation, it is now thought to be constant; the identifier HD 94776 from the Henry Draper catalogue may be used instead. It has an orange hue and is dimly visible to the naked eye with an apparent visual magnitude of 5.93. The distance to this object is approximately 285 light years based on parallax, and it has an absolute magnitude of 1.08. It is drifting closer to the Sun with a radial velocity of −26 km/s.
HD 37974 a variable B[e] hypergiant in the Large Magellanic Cloud. It is surrounded by an unexpected dust disk.
HD 269810 is a blue giant star in the Large Magellanic Cloud. It is one of the most massive and most luminous stars known, and one of only a handful of stars with the spectral type O2.
HD 16028 is a star in the constellation Andromeda. Its apparent magnitude is 5.71. Located approximately 225 parsecs (730 ly) distant, it is an orange giant of spectral type K3III, a star that has used up its core hydrogen and has expanded.
HD 7853 is a double star in the constellation Andromeda. With an apparent magnitude of 6.46, it can barely be seen with the naked eye even on the best of nights. The system is located approximately 130 parsecs (420 ly) distant, and the brighter star is an Am star, meaning that it has unusual metallic absorption lines. The spectral classification of kA5hF1mF2 means that it would have a spectral class of A5 if it were based solely on the calcium K line, F2 if based on the lines of other metals, and F1 if based on the hydrogen absorption lines. The two components are six arc-seconds apart and the secondary is three magnitudes fainter than the primary.
HD 27245, also known as HR 1335 or rarely 25 H. Camelopardalis is a solitary red-hued star located in the northern circumpolar constellation Camelopardalis. It has an apparent magnitude of 5.4, making it faintly visible to the naked eye. Gaia DR3 Parallax measurements place it approximately 607 light years away from it the Solar System and is drifting further away with a heliocentric radial velocity of 25.2 km/s. At its current distance, HD 27245's brightness is diminished by 0.36 magnitudes due to extinction from interstellar dust. It has an absolute magnitude of −0.27.

HD 102350 is a single star in the constellation Centaurus. It has a yellow hue and is visible to the naked eye with an apparent visual magnitude of 4.11. The distance to this star is approximately 390 light years based on parallax, but it is drifting closer with a radial velocity of −3 km/s. It has an absolute magnitude of −1.51.
HD 23319 is an orange-hued star in the constellation Eridanus. It has an apparent visual magnitude of 4.59, which is sufficiently bright to make it visible to the naked eye. The distance to HD 23319 can be estimated from its annual parallax shift of 19.2 mas, which yields a range of about 170 light years. It is moving further away from the Earth with a heliocentric radial velocity of +9.9 km/s.
Theta Sagittae (θ Sagittae) is a double star in the northern constellation of Sagitta. With a combined apparent visual magnitude of +6, it is near the limit of stars that can be seen with the naked eye. According to the Bortle scale the star is visible in dark suburban/rural skies. Based upon an annual parallax shift of 22.15 mas as seen from Earth, it is located roughly 147 light years from the Sun.
HD 180902 is a binary star approximately 342 light years away in the constellation Sagittarius. The primary is a K-type star while the nature of the secondary is unknown since it has only been detected by its effect on the radial velocity of the primary.
IRAS 04509-6922 is a red supergiant star or red hypergiant in the Large Magellanic Cloud. It is one of the largest stars, with a size of nearly 1400 solar radii. If placed in the Solar System, its photosphere would engulf the orbit of Jupiter. This star has a low metallicity. This is a Mira-type variable star currently on the asymptotic giant branch and shrouded in dust. It is pulsating with a period of 1,259±6 d and an amplitude of 0.72±0.04 mag..
SP77 46-44 is a red supergiant star found in the Large Magellanic Cloud in the constellation of Dorado. It is one of the largest stars discovered, with a radius over 1,200 solar radii. If placed in the Solar System, its photosphere would engulf the orbit of Jupiter.
LHA 120-S 79 is an RV Tauri variable star located in the Large Magellanic Cloud, located about 163,000 light years away in the constellation of Dorado, with a period of 37.203 days.
