It is too dim to be visible to the naked eye, having an apparent visual magnitude of 8.31. The system is located at a distance of 188 light years from the Sun based on parallax measurements, but it is drifting closer with a radial velocity of −18 km/s.
HD 11506 is a star in the equatorial constellation of Cetus. It has a yellow hue and can be viewed with a small telescope but is too faint to be visible to the naked eye, having an apparent visual magnitude of 7.51. The distance to this object is 167 light years based on parallax, but it is drifting closer to the Sun with a radial velocity of −7.5 km/s. It has an absolute magnitude of 3.94.
HD 11506 b is an extrasolar planet that orbits the star HD 11506 167 light years away in the constellation of Cetus. This planet was discovered in 2007 by the N2K Consortium using the Keck telescope to detect the radial velocity variation of the star caused by the planet. A second planet, HD 11506 c, was discovered in 2015.
HD 17156, named Nushagak by the IAU, is a yellow subgiant star approximately 255 light-years away in the constellation of Cassiopeia. The apparent magnitude is 8.17, which means it is not visible to the naked eye but can be seen with good binoculars. A search for a binary companion star using adaptive optics at the MMT Observatory was negative.
HD 43691 is a star with an orbiting exoplanet in the constellation Auriga. With an apparent visual magnitude of 8.03, it is too faint to be visible to the naked eye. This system is located at a distance of 279 light years based on parallax measurements, but is drifting closer with a heliocentric radial velocity of −29 km/s.
HD 231701 is a yellow-white hued star in the northern constellation of Sagitta, near the southern constellation border with Aquila. With an apparent visual magnitude of 8.97, it is too dim to be viewed with the naked eye, but can be seen with powerful binoculars or a small telescope. Parallax measurements provide a distance estimate of approximately 356 light years from the Sun, but it is drifting closer with a radial velocity of −63 km/s. It is predicted to come as close as 189.5 light-years in 1.345 million years.
HD 5319 is an 8th magnitude star approximately 319 light years away in the constellation Cetus. It is a subgiant star of spectral type K3, having run out of hydrogen in its core. When it was main-sequence, the spectral type was early F or late A.
HD 109749 is a binary star system about 206 light years away in the constellation of Centaurus. The pair have a combined apparent visual magnitude of 8.08, which is too faint to be visible to the naked eye. The primary component has a close orbiting exoplanet companion. The system is drifting closer with a heliocentric radial velocity of −13.2 km/s.
HD 149143, also called Rosalíadecastro, is a star with a close orbiting exoplanet in the Ophiuchus constellation. Its apparent visual magnitude is 7.89 and the absolute magnitude is 3.87. The system is located at a distance of 239 light years from the Sun based on parallax measurements, and it is drifting further away with a radial velocity of 12 km/s.
HD 88133 b is an extrasolar planet orbiting the star HD 88133. It is probably less massive than Jupiter and even Saturn. It orbits the star in a very tight orbit, completing one revolution around the star in every three and half days or so. Despite the relatively large radius of the star, no transits have been detected.
HD 5319 b is a gas giant exoplanet discovered in 2007 in the constellation of Cetus. This planet has a minimum mass nearly two times that of Jupiter. The planet has an almost circular orbit, with an eccentricity of only 0.02 and a period of 641 days. An additional planet in the system was discovered in 2015 and may be in a 4:3 mean motion resonance with planet b.
HIP 14810 b is a massive hot Jupiter approximately 165 light-years away in the constellation of Aries. It has mass 3.88 times that of Jupiter and orbits at 0.0692 AU. It was discovered by the N2K Consortium in 2006 and the discovery paper was published in 2007. Prior to this a preliminary orbit had been published in the Catalog of Nearby Exoplanets.
HIP 14810 c is an extrasolar planet approximately 165 light-years away in the constellation of Aries. This planet has mass at least 1.28 times that of Jupiter and orbits at 0.545 AU in an eccentric orbit. The planet was discovered by the N2K Consortium in 2006 and announced in a paper published in 2007. With the discovery of a third planet in the system which was announced in 2009, the parameters of this planet were revised.
HD 224693 b, also named Xólotl, is an extrasolar planet orbiting the star HD 224693 every 27 days with a minimum mass 70% of Jupiter.
HD 109749 b is an extrasolar planet that orbits extremely close to the star HD 109749, taking only 5.24 days to orbit at the distance of 0.063 AU. This planet was discovered on August 22, 2005 - the same day as the discovery of Gliese 581 b.
HD 231701 b is an extrasolar planet approximately 356 light years away in the constellation of Sagitta. This planet orbits at 0.55 AU from the star HD 231701 with eccentricity 0.19. Based on its high mass of 1.08 MJ, the planet is probably a gas giant, meaning the planet has no solid surface and have composition similar to Solar System's outer planets.
HD 17156 b, named Mulchatna by the IAU, is an extrasolar planet approximately 255 light-years away in the constellation of Cassiopeia. The planet was discovered orbiting the yellow subgiant star HD 17156 in April 2007. The planet is classified as a relatively cool hot Jupiter planet slightly smaller than Jupiter but slightly larger than Saturn. This highly-eccentric three-week orbit takes it approximately 0.0523 AU of the star at periastron before swinging out to approximately 0.2665 AU at apastron. Its eccentricity is about the same as 16 Cygni Bb, a so-called "eccentric Jupiter". Until 2009, HD 17156 b was the transiting planet with the longest orbital period.
HD 11506 c is an extrasolar planet located approximately 167 light years away in the constellation of Cetus, orbiting the 8th magnitude G-type main sequence star HD 11506. It is the second planet in this system, and its discovery was first claimed in 2009 by using Bayesian analysis on data previously collected by the N2K Consortium. However, in 2015 additional radial velocity measurements showed that the planetary parameters were significantly different from those determined by Bayesian analysis.
HIP 14810 d is an extrasolar planet approximately 165 light-years away in the constellation of Aries. This planet has mass at least 0.57 times that of Jupiter and orbits at 1.89 AU in an eccentric orbit.
HD 125612 c is an extrasolar planet which orbits the G-type main sequence star HD 125612, located approximately 188 light years away in the constellation Virgo. The discovery of this planet was announced by the HARPS team on October 19, 2009, together with 31 other planets, including HD 125612 d.
