Tau Tauri, Latinized from τ Tauri, is a quadruple star system in the constellation Taurus. It is visible to the naked eye as a faint point of light with a combined apparent visual magnitude of 4.33. The distance to this system is approximately about 400 light years based on parallax. The system is moving further from the Earth with a heliocentric radial velocity of +14.6 km/s, and it is a member of the Taurion OB association, located between Orion and Taurus. It is located 0.7 degree north of the ecliptic, and thus is subject to lunar occultations.
67 Ophiuchi is a class B5 Ib star in the constellation Ophiuchus. Its apparent magnitude is 3.93 and it is approximately 1200 light years away based on parallax. It is considered to be a member of the open cluster Collinder 359.
15 Orionis is a suspected astrometric binary star system in the equatorial constellation of Orion, near the border with Taurus. It is visible to the naked eye as a faint, yellow-white hued star with an apparent visual magnitude of 4.82. The system is approximately 340 light years away from the Sun based on parallax. It is moving further from the Earth with a heliocentric radial velocity of +29 km/s, having come to within 69 light-years some three million years ago.
γ Monocerotis, Latinised as Gamma Monocerotis, is a binary star system in the equatorial constellation of Monoceros. Based upon an annual parallax shift of 6.55 mas, it is located roughly 500 light years from the Sun. It can be viewed with the naked eye, having an apparent visual magnitude of 3.96. Gamma Monocerotis is moving away from the Sun with a radial velocity of −5 km/s.
Sigma Persei is an orange K-type giant with an apparent magnitude of +4.36. It is approximately 360 light years from Earth.
Zeta Monocerotis, Latinized from ζ Monocerotis, is a single, yellow-hued star in the constellation Monoceros. It has an apparent visual magnitude of 4.33, which is bright enough to be visible to the naked eye. The annual parallax shift as measured during the Hipparcos mission is 3.08 milliarcseconds, which provides a rough distance estimate of 1,060 light years. It is moving away from the Sun with a radial velocity of +30 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.
Tau Ophiuchi is a multiple star in the constellation Ophiuchus, approximately 167 light years away based on parallax. Its two main components are two yellow-white main sequence stars, A, of magnitude 5.24 and class F2V, and B, of magnitude 5.94 and class F5V, orbiting each other with a period of 257 years and eccentricity around 0.77. A is reported as a spectroscopic binary with a smaller star of 0.29 solar masses orbiting it every 186 days. An additional component, C, has a separation of 100.8" and magnitude 11.28.
1 Pegasi is a triple star system in the constellation Pegasus, located approximately 156 light years away from the Sun based on parallax. It is visible to the naked eye as a faint, orange-hued star with an apparent visual magnitude of 4.09. The system is moving closer to the Earth with a heliocentric radial velocity of −11 km/s.
HD 20468 is a class K2II star in the constellation Perseus. Its apparent magnitude is 4.82 and it is approximately 1180 light years away based on parallax.
HD 63922 is a class B0III star in the constellation Puppis. Its apparent magnitude is 4.11 and it is approximately 1600 light years away based on parallax.
V Puppis is a star system in the constellation Puppis. Its apparent magnitude is 4.41. There is a binary star system at the center with a B1 dwarf orbiting a B3 subgiant star. They have an orbital period of 1.45 days and a distance of only 15 solar radii apart. However, the system moves back and forth, indicating that there is a massive object orbiting them with a period around 5.47 years. Based on the mass of the object, its lack of a visible spectrum, and circumstellar matter in the system with many heavy elements, it is probably a black hole. However, a follow-up study could not confirm this object, but found signs that there may be a third object which is fainter than the other components.
HD 61330 is a class B8IV star in the constellation Puppis. Its apparent magnitude is 4.53 and it is approximately 360 light years away based on parallax.
HD 65810 is a class A2V star in the constellation Puppis. Its apparent magnitude is 4.61 and it is approximately 241 light years away based on parallax.
NV Puppis, also known as υ1 Puppis, is a class B2V star in the constellation Puppis. Its apparent magnitude is 4.67 and it is approximately 800 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.
19 Puppis is a binary star system in the southern constellation of Puppis, near the northern border with Hydra and Monoceros. It is visible to the naked eye as a faint, yellow-hued star with an apparent visual magnitude of 4.72. The system is located approximately 177 light years away from the system based on parallax. It is receding from the Earth with a heliocentric radial velocity of +36 km/s, having come to within 31 light-years some 1.4 million years ago.
