    HD 132406 b is a long period massive gas giant extrasolar planet orbiting the Sun-like star HD 132406. HD 132406 b has at least 5.61 times the mass of Jupiter. The orbital distance from the star is almost twice that of from Earth to the Sun. The orbital period is 2.7 years. [1]

    An astrometric measurement of the planet's inclination and true mass was published in 2022 as part of Gaia DR3. [2]

    Iota Horologii Star in the constellation Horologium

    Iota Horologii, Latinized from ι Horologii, is a yellow-hued star approximately 56.5 light-years away in the Horologium constellation. The star is classified as a G0Vp yellow dwarf. It has a mass and radius larger than the Sun, and is about 50% more luminous.

    HD 28185 is a yellow dwarf star similar to our Sun located about 128.6 light-years away from Earth in the constellation Eridanus. The designation HD 28185 refers to its entry in the Henry Draper catalogue. The star is known to possess one long-period extrasolar planet.

    HD 1237 is a binary star system approximately 57 light-years away in the constellation of Hydrus.

    HD 102195 is an orange-hued star in the zodiac constellation of Virgo with a confirmed exoplanet companion. With an apparent visual magnitude of 8.07, the star is too faint to be seen with the naked eye. The distance to HD 102195 can be estimated from its annual parallax shift of 34.06 mas, yielding a separation of 95.8 light years. It is moving further away from the Earth with a heliocentric radial velocity of 1.85 km/s. This is a high proper motion star and a possible member of the η Cha stellar kinematic group.

    Gliese 849, or GJ 849, is a small, solitary star in the equatorial constellation of Aquarius. It has a reddish hue and is invisible to the naked eye with an apparent visual magnitude of 10.41. The distance to this star is 28.7 light years based on parallax, but it is drifting closer to the Sun with a radial velocity of −15.3 km/s. It has a pair of confirmed gas giant companions.

    HD 219828 is a star with two exoplanetary companions in the constellation of Pegasus. With an apparent visual magnitude of 8.04, it is an eighth magnitude star that is too dim to be readily visible to the naked eye. The star is located at a distance of approximately 239 light years from the Sun based on parallax measurements, but is drifting closer with a radial velocity of −24 km/s.

    HD 43691 is a G-type star with magnitude +8.03 located approximately 280 light-years away in the constellation Auriga. This yellow star is about to stop thermonuclear hydrogen-fusion in its core and eventually expand to become a red giant.

    HD 132406 is a star in the northern constellation of Boötes. With an apparent visual magnitude of 8.45, it is invisible to the naked eye. The distance to this star is 231 light years based on parallax, but it is drifting closer with a radial velocity of −37.8 km/s. The star has an absolute magnitude of 4.30. It has one confirmed exoplanet companion.

    HD 24040 is a metal-rich G-type star located approximately 152 light-years away in the constellation of Taurus. In 2006 a long-period planet was discovered.

    HD 43691 b is a massive jovian planet located approximately 280 light-years away in the constellation of Auriga. Because the inclination is unknown, only the minimum mass is known. The planet orbits close to the star, closer than Mercury to the Sun.


    HD 192699 b is an exoplanet located approximately 214 light-years away in the constellation of Aquila, orbiting the star HD 192699. This planet was discovered in April 2007, massing at least 2.5 times the mass of Jupiter (MJ). Despite its orbital distance more than that of Earth, the orbital period is less than a year, because the parent star is more massive than the Sun.

    HD 24040 b is a long-period exoplanet taking approximately 3500 days to orbit at 4.6 astronomical units in an almost circular orbit. It has a minimum mass 4 times that of Jupiter.

    HD 131664 is an 8th magnitude star in the southern constellation of Apus with an orbiting brown dwarf companion. Parallax measurements by the Gaia space observatory provide an estimated distance of 172.5 light years from the Earth. The system is moving further away with a baseline heliocentric radial velocity of +35 km/s.

    HD 16760 is a binary star system approximately 227 light-years away in the constellation Perseus. The primary star HD 16760 is a G-type main sequence star similar to our Sun. The secondary, HIP 12635 is 1.521 magnitudes fainter and located at a separation of 14.6 arcseconds from the primary, corresponding to a physical separation of at least 660 AU. Announced in July 2009, HD 16760 has been confirmed to have a red dwarf orbiting it, formerly thought to be a brown dwarf or exoplanet.

    HD 175167 is a star with an exoplanet companion in the southern constellation of Pavo. It is too faint to be visible with the naked eye at an apparent visual magnitude of 8.01. The system is located at a distance of 232 light years from the Sun based on parallax measurements, and it is drifting further away with a radial velocity of 5 km/s. It shows a high proper motion, traversing the celestial sphere at an angular rate of 0.190 arcsec yr−1.

    HD 131399 Star in the constellation Centaurus

    HD 131399 is a star system in the constellation of Centaurus. Based on the system's electromagnetic spectrum, it is located around 351 light-years away. The total apparent magnitude is 7.07, but because of interstellar dust between it and the Earth, it appears 0.22 ± 0.09 magnitudes dimmer than it should be.
