HD 68601 is a class A7Ib [3] (white supergiant) star in the constellation Puppis. Its apparent magnitude is 4.75 [2] and it is approximately 4,200 light years away based on parallax. [1]
It has one companion, B, with magnitude 9.81 and separation 26.4". [8]
ν Persei, Latinized as Nu Persei, is a single star and a suspected variable in the northern constellation of Perseus. It has a yellow-white hue and is visible to the naked eye with an apparent visual magnitude of 3.80. This object is located approximately 560 light-years from the Sun based on parallax but is drifting closer with a radial velocity of −12 km/s.
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.
17 Monocerotis is a single star located around 490 light years away from the Sun 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 4.77. The star is moving away from the Earth with a heliocentric radial velocity of +46 km/s.
19 Monocerotis is a single, variable star in the equatorial constellation of Monoceros, located approximately 1,220 light years away from the Sun based on parallax. It has the variable star designation V637 Monocerotis, while 19 Monocerotis is the Flamsteed designation. This object is visible to the naked eye as a faint, blue-white hued star with a baseline apparent visual magnitude of 5.00. It is receding from the Earth with a heliocentric radial velocity of +25 km/s.
HD 103079 is a class B4V star in the constellation Musca. Its apparent magnitude is 4.89 and it is approximately 362 light years away from Earth based on parallax. It is a member of the Lower Centaurus–Crux subgroup of the Scorpius–Centaurus association, a group of predominantly hot blue-white stars that share a common origin and proper motion across the galaxy.
42 Orionis is a class B1V star in the constellation Orion. Its apparent magnitude is 4.59 and it is approximately 900 light years away based on parallax.
31 Pegasi is a single star in the northern constellation of Pegasus. It is visible to the naked eye as a dim, blue-white hued point of light with a baseline apparent visual magnitude of 4.99. It is located approximately 1,600 light years away from the Sun based on parallax, but is drifting closer with a radial velocity of −5.3 km/s.
17 Persei is a single star in the northern constellation of Perseus, located about 390 light years away from the Sun.
