Lambda Caeli, Latinized from λ Caeli, is a star in the constellation Caelum. It is also known by its designations HD 30202 and HR 1518. [8] This star is a challenge to view with the naked eye, having an apparent visual magnitude of 6.24. [2] Based on parallax measurements, Lambda Caeli is known to be around 700 light-years distant from the Sun, but is drifting closer with a radial velocity of −4 km/s. [5]
This object is an aging K-type giant star with a stellar classification of K3/4III. [3] Having exhausted the supply of hydrogen at its core, it has cooled and expanded; now having 31 times the radius of the Sun. It is radiating 274 times the Sun's luminosity from its swollen photosphere at an effective temperature of 4,189 K. [1]
19 Aquarii is a star in the zodiac constellation of Aquarius. With an apparent magnitude of about 5.7, the star is barely visible to the naked eye as a white-hued star. Parallax estimates put it at a distance of about 260 light years away from the Sun. The star is moving closer to the Earth with a heliocentric radial velocity of −21 km/s.
59 Aurigae, often abbreviated as 59 Aur, is a star in the constellation Auriga. Its baseline apparent magnitude is 6.1, meaning it can just barely be seen with the naked eye as a dim, yellow-white hued star. Based on parallax measurements, it is located about 483 light-years away from the Sun.
Iota Canis Majoris is a variable supergiant star in the constellation Canis Major.
Mu Lyrae is a star in the constellation Lyra. It has the traditional name Alathfar, from the Arabic الأظفرal-ʼuẓfur "the talons ", a name it shares with Eta Lyrae.
2 Centauri is a single star in the southern constellation of Centaurus, located approximately 183 light years from Earth. It has the Bayer designation g Centauri; 2 Centauri is the Flamsteed designation. This object is visible to the naked eye as faint, red-hued star with an apparent visual magnitude of 4.19. It is moving away from the Earth with a heliocentric radial velocity of +41 km/s. The star is a member of the HD 1614 supercluster.
5 Tauri is a binary star in the zodiac constellation of Taurus, located approximately 530 light years from the Sun. It is visible to the naked eye as a faint orange-hued star with an apparent visual magnitude of +4.14. It is moving further from the Earth with a heliocentric radial velocity of +14 km/s.
HD 220466 is a F-type subgiant or main sequence star in the constellation Aquarius. It has apparent magnitude 6.47 and is about 200 light-years away. In 1913, an apparent visual companion of apparent magnitude 10.3 was observed 1.9 arcseconds away from the star, but it is doubtful whether it exists.
HD 180262 is a wide double star in the equatorial constellation of Aquila. The pair have an angular separation of 89.823″.
IQ Aurigae is a single, variable star in the northern constellation of Auriga. It is visible to the naked eye as a dim, white-hued star with an apparent visual magnitude that fluctuates around 5.38. The star is located at a distance of about 470 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +28.6 km/s.
4 Camelopardalis is a binary star in the northern constellation of Camelopardalis, located 179 light years away from the Sun, based upon parallax. With a combined apparent visual magnitude of 5.29, it is visible to the naked eye as a faint, white-hued star. The pair have a relatively high proper motion, traversing the celestial sphere at an angular rate of 0.158″ per year. The system's proper motion makes it a candidate for membership in the IC 2391 supercluster. They are moving away from the Earth with a heliocentric radial velocity of 22.5 km/s.
HD 112028 is an evolved star in the northern constellation of Camelopardalis. It has spectral peculiarities that have been interpreted as a shell, and also relatively weak magnesium and silicon lines. Its spectral class has been variously assigned between B9 and A2, and its luminosity class between a subgiant and bright giant.
54 Eridani is a suspected astrometric binary star system located around 400 light years from the Sun in the equatorial constellation of Eridanus. It is visible to the naked eye as a faint, reddish hued star with a baseline apparent visual magnitude of 4.32. The object is moving closer to the Earth with a heliocentric radial velocity of −33 km/s.

It has the variable star designation V669 Herculis and the Bayer designation A Herculis, while 104 Herculis is the Flamsteed designation. This object is visible to the naked eye as a dim, red-hued point of light with a baseline apparent visual magnitude of 4.96. It is moving closer to the Earth with a heliocentric radial velocity of −1.2 km/s.
Lambda Coronae Borealis, Latinised from λ Coronae Borealis, is a star located in the constellation Corona Borealis, at a distance of 41.6 parsecs (136 ly). It is also known as HR 5936, and HD 142908.
HD 100307 is a suspected variable star in the constellation of Hydra. Its apparent magnitude is 6.16, but interstellar dust makes it appear 0.346 magnitudes dimmer than it should be. It is located some 340 light-years away, based on parallax.
1 Lupi is a solitary giant star in the southern constellation of Lupus. It has the Bayer designation i Lupi; 1 Lupi is the Flamsteed designation. The apparent visual magnitude is 4.90, which indicates it is faintly visible to the naked eye. Based on parallax measurements, this star is approximately 1,800 light years from the Sun. It is moving closer to the Earth with a heliocentric radial velocity of −23 km/s.
90 Tauri is a star in the zodiac constellation of Taurus, located 144 light years away from the Sun. It is visible to the naked eye as a faint, white-hued star with an apparent visual magnitude of 4.27. 90 Tauri is a member of the Hyades cluster and is listed as a double star.
