The star is located at a distance of 120 light years from the Sun based on parallax. It is drifting closer with a radial velocity of −17.3 km/s, and is predicted to come as close as 20.7 ly (6.4 pc) in 2.08 million years. HD 169830 is known to be orbited by two large Jupiter-like exoplanets.
HD 38529 is a binary star approximately 138 light-years away in the constellation of Orion.
HD 40979 is a triple star system in the northern constellation of Auriga. The combined brightness of this group lies below the typical limit of visibility to the naked eye at an apparent visual magnitude of 6.74. It is located at a distance of approximately 108 light years from the Sun based on parallax. The system is receding with a radial velocity of +32 km/s. It has a relatively high rate of proper motion, traversing the celestial sphere at the rate of 0.182″ per year.
HD 12661 c is a giant exoplanet one and a half times the mass of Jupiter orbiting around HD 12661.
HD 12661 b is a giant exoplanet two and a half times the mass of Jupiter orbiting around the star HD 12661.
HD 66428 is a G-type main sequence star located approximately 174 light-years away in the constellation of Monoceros. This star is similar to the Sun with an apparent magnitude of 8.25, an effective temperature of 5705 ± 27 K and a solar luminosity 1.28. Its absolute magnitude is 11.1 while its U-V color index is 0.71. It is considered an inactive star and it is metal-rich . This star has a precise mass of 1.14552 solar masses. This precision comes from the Corot mission that measured asteroseismology.
HD 11964 b is an extrasolar planet, a gas giant like Jupiter approximately 110 light-years away in the constellation of Cetus. The planet orbits the yellow subgiant star HD 11964 in a nearly-circular orbit, taking over 5 years to complete a revolution around the star at a distance of 3.34 astronomical units.
79 Ceti b is an extrasolar planet orbiting 79 Ceti every 75 days. Discovered along with HD 46375 b on March 29, 2000, it was the joint first known extrasolar planet to have minimum mass less than the mass of Saturn.
HD 68988 is a star in the northern constellation of Ursa Major. It has been given the proper name Násti, which means star in the Northern Sami language. The name was selected in the NameExoWorlds campaign by Norway, during the 100th anniversary of the IAU. HD 68988 is too faint to be seen with the naked eye, having an apparent visual magnitude of 8.20. The star is located at a distance of 199 light years from the Sun based on parallax. It is drifting closer with a radial velocity of −69 km/s and is predicted to come as close as 78 light-years in 617,000 years.
HD 50554 is a single, Sun-like star with an exoplanetary companion in the northern constellation of Gemini. It has an apparent visual magnitude of +6.84, which makes it a 7th magnitude star; it is not visible to the naked eye, but can be viewed with binoculars or a telescope. The system is located at a distance of 102 light-years from the Sun based on parallax, but is drifting closer with a radial velocity of −4 km/s.
HD 195019 is a star system in the constellation of Delphinus. Star B is located at projected separation of 131 AU from Star A. This star system is located 123 light-years away from the Sun, Earth and Solar System. HD 195019 A is a yellow dwarf or subgiant [G3IV-V]. Star HD 195019 B, detected by spectrometry, was initially believed to be a smaller and dimmer orange dwarf of the K3 type, although later (2003) research failed to detect any stellar companion.
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.
HD 210277 b is an extrasolar planet orbiting the star HD 210277. It was discovered in September 1998 by the California and Carnegie Planet Search team using the highly successful radial velocity method. The planet is at least 24% more massive than Jupiter. The mean distance of the planet from the star is slightly more than Earth's distance from the Sun. However, the orbit is very eccentric, so at periastron this distance is almost halved, and at apastron it is as distant as Mars is from the Sun.
HD 30177 b is an extrasolar planet located approximately 181.6 light-years away in the constellation of Dorado, orbiting the star HD 30177.
HD 50554 b is a Jupiter-sized extrasolar planet with minimum mass 4.4 times that of Jupiter. The planet was announced in 2001 by the European Southern Observatory and confirmed in 2002 using observations from the Lick and Keck telescopes.
HD 106252 b is a large gas giant extrasolar planet about 10 times more massive than Jupiter. It was announced in 2001 by the European Southern Observatory. The discovery was confirmed by a different team using the Lick Telescope.
HD 68988 c is an exoplanet located approximately 192 light-years away in the constellation of Ursa Major, orbiting the star HD 68988. The parameters including period and eccentricity are highly uncertain. The semimajor axis was initially believed to be 5.32 AU with an orbital period of 4100 ± 7300 days. The planetary orbit was significantly refined in 2021.
