AK Pyxidis is a semiregular variable star located in the constellation Pyxis. It varies between magnitudes 6.09 and 6.51, [3] pulsating to multiple periods simultaneously of 55.5, 57.9, 86.7, 162.9 and 232.6 days. [1] Located around 1228 light-years distant, it shines with a luminosity approximately 1500 times that of the Sun and has a surface temperature of 3410 K. [4]
62 Sagittarii is a single, variable star in the constellation of Sagittarius. It has the Bayer designation c Sagittarii and the variable star designation V3872 Sagittarii, while 62 Sagittarii is its Flamsteed designation. This object forms the southwest corner of the asterism called the Terebellum. It is visible to the naked eye with an apparent visual magnitude that varies between 4.45 and 4.64, and, at its peak, it is the brightest of the four stars in the Terebellum. 62 Sagittarii is the star in the Terebellum which is most distant from its centre; it is 1.72° from its northwest corner, 60 Sagittarii, and 1.37° from its southeast corner, 59 Sagittarii. This star is located approximately 450 light-years from the Sun based on parallax, and is drifting further away with a radial velocity of +10 km/s.
Omega Virginis is a solitary star in the zodiac constellation Virgo. It has an apparent visual magnitude of +5.2, which is bright enough to be faintly visible to the naked eye. Based upon an annual stellar parallax shift of 6.56 milliarcseconds, it is located about 500 light years from the Sun.
Chi Aquarii, Latinized from χ Aquarii, is the Bayer designation of a star in the equatorial constellation of Aquarius. The distance to this star, based upon parallax measurements with a 7% margin of error, is roughly 610 light-years. It is visible to the naked eye with an apparent visual magnitude of about 5.
15 Arietis is a single variable star in the northern constellation of Aries. 15 Arietis is the Flamsteed designation; it also bears the variable star designation AV Arietis. It has an apparent visual magnitude of 5.74, which is just bright enough to be visible to the naked eye from dark suburban skies. An annual parallax shift of 5.84 mas corresponds to a physical distance of approximately 560 light-years from Earth. At that distance, the star's brightness is reduced by 0.33 in magnitude because of extinction from interstellar gas and dust.
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 HR 1614 supercluster.
Tau4 Eridani is a binary star system in the constellation Eridanus. It is visible to the naked eye with an apparent visual magnitude of 3.65. The distance to this star can be estimated using the parallax method, which yields a value of roughly 300 light years.
V450 Aquilae is semi-regular pulsating star in the constellation Aquila. Located around 660 light-years distant, it shines with a luminosity approximately 2172 times that of the Sun and has a surface temperature of 3326 K.
HD 118508 is a variable star in the northern constellation of Boötes. It varies marginally in luminosity with an amplitude of 0.04 in magnitude.
Zeta Circini, Latinized from ζ Circini, is the Bayer designation for a star located in the southern constellation of Circinus. With an apparent visual magnitude of 6.08, it is barely visible to the naked eye on a dark night. The distance to this star, as estimated using an annual parallax shift of 2.56 mas, is around 1,300 light years.
Epsilon Pyxidis (ε Pyxidis) is quadruple star system in the southern constellation of Pyxis. It is faintly visible to the naked eye, having a combined apparent visual magnitude of +5.60. Based upon an annual parallax shift of 15.39 mas as seen from Earth, it is located around 212 light years from the Sun. The system is deemed to be a member of the Sirius supercluster of stars that share a common motion through space.
Theta Pyxidis, Latinized from θ Pyxidis, is a red M-type giant in the constellation Pyxis. It is approximately 500 ± 30 light years from Earth. It is of spectral type M1III and semi-regular variable with two measured periods of 13 and 98.3 days, and an average visual magnitude of 4.71, It shines with a luminosity approximately 970 times that of the Sun and has a surface temperature of 3825 K. It has a diameter around 54 times that of the Sun.
7 Ceti is a single, variable star in the equatorial constellation of Cetus. It has the variable star designation AE Ceti. The star is visible to the naked eye with a baseline apparent visual magnitude of 4.44. Based upon an annual parallax shift of only 7.3 mas, it is located roughly 450 light years away. It is moving closer to the Sun with a heliocentric radial velocity of −23 km/s. Eggen (1965) listed it as a probable member of the Wolf 630 group of co-moving stars.
Tau9 Eridani is a binary star in the constellation Eridanus. It is visible to the naked eye with an apparent visual magnitude of 4.63. The distance to this system can be estimated using the parallax method, which yields a value of roughly 327 light years.
Tau8 Eridani, Latinized from τ8 Eridani, is a binary star system in the constellation Eridanus. It is visible to the naked eye with a combined apparent visual magnitude of 4.65. The distance to this system can be estimated via the parallax method, yielding a value of around 380 light years.
Delta2 Gruis, Latinized from δ2 Gruis, is a solitary, red-hued star in the southern constellation of Grus. It is visible to the naked eye with an apparent visual magnitude of about 4. Based upon an annual parallax shift of 9.88 mas as seen from the Earth, the star is located around 330 light years from the Sun. It is moving further away from the Sun with a radial velocity of +3 km/s.
Phi2 Hydrae, Latinized from φ2 Hydrae, is a star in the constellation Hydra. It originally received the Flamsteed designation of 1 Crateris before being placed in the Hydra constellation. Based upon an annual parallax shift of 4.31 mas as seen from Earth, it is located roughly 760 light years from the Sun. The star is faintly visible to the naked with an apparent visual magnitude of 6.09. It forms a triangle with the fainter φ1 Hydrae and the brighter φ3 Hydrae, between μ Hydrae and ν Hydrae.
Pi5 Orionis (π5 Ori, π5 Orionis) is a binary star system in the constellation Orion. It has an apparent visual magnitude of 3.69, which is bright enough to be visible to the naked eye on a clear night. Based upon an annual parallax shift of 2.43 mas, it is around 1,300 light-years distant from the Sun.
Omicron1 Orionis is a binary star in the northeastern corner of the constellation Orion. It is visible to the naked eye with an apparent visual magnitude of 4.7. Based upon an annual parallax shift of 5.01±0.71 mas, it is located approximately 650 light years from the Sun. At that distance, the visual magnitude of the star is diminished by an interstellar absorption factor of 0.27 due to intervening dust.
9 Pegasi is a supergiant star in the constellation Pegasus. Its apparent magnitude is 4.35.
TT Corvi is a semiregular variable star in the constellation Corvus. It is a red giant of spectral type M3III and average apparent magnitude 6.48 around 923 light years distant. It shines with a luminosity approximately 993 times that of the Sun and has a surface temperature of 3630 K.
