Epsilon Eridani, formally named Ran, is a star in the southern constellation of Eridanus, at a declination of 9.46° south of the celestial equator. This allows it to be visible from most of Earth's surface. At a distance of 10.5 light-years from the Sun, it has an apparent magnitude of 3.73. It is the third-closest individual star or star system visible to the unaided eye.
82 G. Eridani is a star about 20 light years away from Earth in the constellation Eridanus. It is a main-sequence star with a stellar classification of G6 V, and it hosts a system of at least three planets and a dust disk.
HD 10647 is a 6th-magnitude yellow-white dwarf star, 57 light-years away in the constellation of Eridanus. The star is visible to the unaided eye under very dark skies. It is slightly hotter and more luminous than the Sun, and at 1,750 million years old, it is also younger. An extrasolar planet was discovered orbiting this star in 2003.
23 Librae b also known as HD 134987 b is an extrasolar Jovian planet discovered in November 1999 orbiting the star 23 Librae. It orbits in its star's habitable zone.
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 its star every 75 days. 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 2039 b is an extrasolar planet orbiting the star HD 2039. It is almost five times as massive as Jupiter and has a very eccentric orbit.
Epsilon Eridani b, also known as AEgir, is an exoplanet approximately 10.5 light-years away orbiting the star Epsilon Eridani, in the constellation of Eridanus. The planet was discovered in 2000, and as of 2019 remains the only confirmed planet in its planetary system. It orbits at around 3.5 AU with a period of around 7.4 years, and has a mass around 1.2 times that of Jupiter.
HD 196050 is a triple star system located in the southern constellation of Pavo. This system has an apparent magnitude of 7.50 and the absolute magnitude is 4.01. It is located at a distance of 112 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +61 km/s. It is also called by the Hipparcos number 101806.
HD 117618 b, named Noifasui by the IAU, is an exoplanet discovered orbiting the star HD 117618 in September 2004. The planet is a small gas giant less than a fifth the mass of Jupiter. It orbits close to its star in a very eccentric orbit.
HD 117207 b is an extrasolar planet orbiting at 3.79 astronomical units taking about 2597 days to complete its orbit around HD 117207. Its orbit is moderate in eccentricity. This planet was announced in January 2005 by Marcy in Keck Observatory. The planet has at least 1.88 Jupiter masses.
HD 75289 b is an extrasolar planet orbiting the star HD 75289 in Vela constellation. It has a minimum mass half that of Jupiter, and it orbits in a very short orbit completing one circular revolution around the star in three and a half days. By studying the starlight scientists have concluded that the planet must have an albedo less than 0.12, rather low for a gas giant. Otherwise its reflected light would have been detected.
HD 20367 b is an extrasolar planet approximately 88 light years away in the constellation of Aries. It has mass similar to that of Jupiter. It orbits the star at a mean distance that is a quarter farther than Earth orbits from the Sun. The 470-day orbit is somewhat eccentric. However, subsequent observations put the existence of this planet strongly in doubt.
HD 188015 b is an extrasolar planet announced by the California and Carnegie Planet Search team in 2005. Like majority of known planets, it was discovered using the radial velocity method.
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.
BD-10°3166 b is an extrasolar planet approximately 268 light-years away in the constellation of Crater. This planet is a so-called "Hot Jupiter," a planet that orbits its parent star in a very close orbit. Distance to the star is less than 1/20th Earth's distance from the Sun. No transits by the planet have been detected, so the planet's orbital plane cannot be exactly aligned with our direction of view.
HD 30177 b is an extrasolar planet located approximately 181.6 light-years away in the constellation of Dorado, orbiting the star HD 30177. This is one of the most massive planets ever detected by the radial velocity method. In addition, the planet orbits far from the star, about 4 AU away, taking 2770 days to orbit the star. Even though the massive planet is orbiting at 4 AU from the star, the radial velocity semi-amplitude is high, around 146.8±2.8 m/s. Since the inclination is not known, this planet candidate may in fact be a brown dwarf.
HD 114729 b is an extrasolar planet approximately 114 light years away in the constellation of Centaurus. This planet is probably slightly less massive than Jupiter. It is an "eccentric Jupiter" meaning that it does not orbit very near the star like the famous 51 Pegasi b but further out and its orbit is very oval-shaped. The mean distance from the star is 2.11 AU, about twice the Earth's distance from the Sun. At periastron, the planet is only 1.43 AU from the star, and at apoastron, the orbital distance is 2.72 AU.
HD 208487 b is an extrasolar planet located approximately 144 light-years away in the constellation of Grus, orbiting the star HD 208487. This planet has a minimum mass close to half that of Jupiter and is most probably a gas giant. The planet orbits the star in a close, eccentric orbit. One revolution takes 130 days to complete. This planet was discovered on September 16, 2004 by Tinney, Butler, and Marcy et al. using Doppler spectroscopy to measure the star's radial velocity changing over time as the planet revolves around its orbit.
HD 102117 b, formally named Leklsullun, is a planet that orbits the star HD 102117. The planet is a small gas giant a fifth the size of Jupiter. It orbits very close to its star, but not in a "torch orbit" like the famous 51 Pegasi b. It is one of the smallest extrasolar planets discovered so far.
