HD 18970 is a class G9.5III [3] (yellow giant) star in the constellation Perseus. Its apparent magnitude is 4.77 [2] and it is approximately 211 light years away based on parallax. [1]
μ Sculptoris, Latinized as Mu Sculptoris, is a solitary, orange-hued star in the southern constellation of Sculptor. It is visible to the naked eye as a dim point of light with an apparent visual magnitude of +5.30. This star is located approximately 291 light years from the Sun based on parallax, and it is drifting further away with a radial velocity of +16 km/s.
1 Aurigae is the original name for a star now in the constellation Perseus. It was the first entry in John Flamsteed's catalogue of stars in Auriga. When Eugène Joseph Delporte drew up simplified boundaries for the constellations on behalf of the International Astronomical Union in 1930, 1 Aurigae ended up over the border in Perseus. To avoid confusion, the star may instead be referred to by its Harvard Revised catalogue number, HR 1533.
ε Monocerotis, Latinised as Epsilon Monocerotis, is the Bayer designation of a binary star system in the equatorial constellation Monoceros. Its location is a guide for sky navigation toward the Rosette Nebula.
Sigma Persei is an orange K-type giant with an apparent magnitude of +4.36. It is approximately 360 light years from Earth.
10 Leonis Minoris is a single, variable star in the northern constellation Leo Minor, located approximately 180 light years away based on parallax. It has the variable star designation SU Leonis Minoris; 10 Leonis Minoris is the Flamsteed designation. This body is visible to the naked eye as a faint, orange-hued star with a baseline apparent visual magnitude of 4.54. It is moving closer to the Earth with a heliocentric radial velocity of −12 km/s.
18 Monocerotis is a binary star system located about half way from Orion's Belt to Procyon, in the equatorial constellation of Monoceros. It is visible to the naked eye as a faint, orange-hued star with an apparent visual magnitude of 4.47, and is positioned around 370 light years away from the Sun based on parallax. The system is receding from the Earth with a heliocentric radial velocity of +11 km/s.
24 Scorpii is a star that was originally placed by John Flamsteed within the constellation of Scorpius but in now placed within the southeastern constellation of Ophiuchus. It is visible to the naked eye as a faint, yellow-hued point of light with an apparent visual magnitude of 4.91. Based on the trigonometric parallax published in Gaia Data Release 2, the star lies approximately 121 parsecs or 390 light years away. It is positioned near the ecliptic and thus is subject to lunar occultations.
11 Orionis is a solitary Ap star in the equatorial constellation of Orion, near the border with Taurus. It is visible to the naked eye with an apparent visual magnitude of 4.65, and it is located approximately 365 light years away from the Sun based on parallax. The star is moving further from the Sun with a heliocentric radial velocity of +16.8 km/s.
31 Orionis is a binary star system in the equatorial constellation of Orion, located near the bright star Mintaka. It is visible to the naked eye as a faint, orange-hued point of light with a baseline apparent visual magnitude of 4.71. The distance to this system is approximately 490 light years away based on parallax, and it is drifting further away with a mean radial velocity of +6 km/s.
72 Pegasi is a binary star system in the northern constellation of Pegasus. It is visible to the naked eye as a faint, orange-hued point of light with a combined apparent visual magnitude of 4.97. The system is located approximately 550 light years away from the Sun, based on parallax, but is drifting closer with a radial velocity of −25 km/s.
24 Persei is a star in the northern constellation of Perseus, located around 337 light years from the Sun. It is visible to the naked eye as a faint, orange-hued star with an apparent visual magnitude of 4.94. The object is moving closer to the Earth with a heliocentric radial velocity of −37 km/s.
QZ Puppis is a class B2.5V star in the constellation Puppis. Its apparent magnitude is 4.49 and it is approximately 650 light years away based on parallax.
HD 63744 is a class K0III star in the constellation Puppis. Its apparent magnitude is 4.71 and it is approximately 232 light years away based on parallax.
HD 61772 is a class K3II star in the constellation Puppis. Its apparent magnitude is 4.98 and it is approximately 700 light years away based on parallax.
HD 50235 is a class K5III star located approximately 811 light years away, in the constellation Puppis. Its apparent magnitude is 4.99. HD 50235 made its closest approach to the Sun 7.8 million years ago, at the distance of 137 light years, during which it had an apparent magnitude of 1.13.
43 Sagittarii is a single star in the southern constellation of Sagittarius. It has the Bayer designation d Sagittarii, while 43 Sagittarii is the Flamsteed designation. This object is visible to the naked eye as a faint, yellow-hued star with an apparent visual magnitude of 4.88. From parallax measurements, it is estimated to lie around 470 light years away from the Sun. The star is drifting further from the Earth with a heliocentric radial velocity of +15.2 km/s. It is located near the ecliptic and thus is subject to lunar occultations.
HD 190056 is a class K1III star in the constellation Sagittarius. Its apparent magnitude is 4.99 and it is approximately 291 light years away based on parallax.
Theta2 Microscopii is a class A0III star in the constellation Microscopium. Its apparent magnitude is 5.76 and it is approximately 390 light years away based on parallax. It is an Ap star, a chemically peculiar star with unusually strong metallic spectral lines.
HD 42540, also known as HR 2196, is a suspected variable star in the constellation Pictor. A class K2-3III orange giant, its apparent magnitude is 5.04 and it is approximately 362 light years away based on parallax.
Epsilon Octantis, Latinized from ε Octantis, is a star in the southern circumpolar constellation of Octans. It is a faintly visible to the naked eye with an apparent visual magnitude of 5.09. The annual parallax shift of 11.22 mas yields a distance estimate of around 291 light years. It is moving further from the Sun with a radial velocity of +11.7 km/s.
