HD 82943 is a yellow dwarf star approximately 89 light-years away in the constellation of Hydra. Two extrasolar planets have been confirmed to be orbiting it, and it is thought that the system had more giant planets that were "swallowed" by the parent star. HD 82943 is estimated at 1.15 times the mass of the Sun.
HD 169830 is a star in the southern constellation of Sagittarius. It has a yellow-white hue and is dimly visible to the naked eye with an apparent visual magnitude of +5.90. 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 83443 is an orange dwarf star approximately 134 light-years away in the constellation of Vela. As of 2000, at least one extrasolar planet has been confirmed to be orbiting the star. The star HD 83443 is named Kalausi. The name was selected in the NameExoWorlds campaign by Kenya, during the 100th anniversary of the IAU. The word Kalausi means a very strong whirling column of wind in the Dholuo language.
HD 216770 is an 8th-magnitude star located approximately 124 light-years away in the constellation of Piscis Austrinus. It is an orange dwarf, and is somewhat dimmer and cooler than the Sun.
HD 114386 is a 9th magnitude star located approximately 91 light years away in the constellation of Centaurus. It is an orange dwarf, and rather dim compared to the Sun. It can be seen with a telescope or good binoculars.
HD 1237 is a binary star system approximately 57 light-years away in the constellation of Hydrus.
94 Ceti is a trinary star system approximately 73 light-years away in the constellation Cetus.
94 Ceti b or 94 Ceti Ab to distinguish it from the distant red dwarf companion, is an extrasolar planet orbiting its star once every 1.2 years. It was discovered on August 7, 2000 by a team led by Michel Mayor.
HD 142415 is a single star in the southern constellation of Norma, positioned next to the southern constellation border with Triangulum Australe and less than a degree to the west of NGC 6025. With an apparent visual magnitude of 7.33, it is too faint to be visible to the naked eye. The distance to this star is 116 light years from the Sun based on parallax, but it is drifting closer with a radial velocity of −12 km/s. It is a candidate member of the NGC 1901 open cluster of stars.
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 6434 b is an extrasolar planet orbiting the star HD 6434. It has a minimum mass about half that of Jupiter. It orbits the star very close, over 2.5 times as close as Mercury orbits the Sun. For this reason it completes one orbit in only 22 days. Unlike true "hot Jupiters" like 51 Pegasi b, HD 6434 b does not have a circular orbit, but rather an eccentric one.
HD 216770 b is an extrasolar planet orbiting the star HD 216770. It has a mass about two thirds that of Jupiter, largest planet in the Solar System. But unlike the gas giants in the Solar System, it orbits in a very eccentric orbit around the star. The mean distance from the star is slightly larger than Mercury's, and it completes one orbit around the star in every 118 days.
HD 111232 b is an extrasolar planet that orbits at almost 2 AU with a minimum mass of 6.8 times that of Jupiter. This planet was discovered in the La Silla Observatory by Michel Mayor using the CORALIE spectrograph on 30 June 2003, along with six other planets, including HD 41004 Ab, HD 65216 b, HD 169830 c, HD 216770 b, HD 10647 b, and HD 142415 b.
HD 169830 c is an extrasolar planet, most likely a gas giant, with a minimum mass three and a half times that of Jupiter. Its orbit is eccentric, with a period (year) of 1830 days. In 2022, the true mass and inclination of HD 169830 c were measured via astrometry.
HD 121504 b is an exoplanet that is likely to be slightly less massive than Jupiter. Although the radial velocity method that was used to detect the planet can only measure the minimum mass of the planet, it is very unlikely that its true mass would be much higher.
HD 65216 b is an extrasolar planet located approximately 115 light-years away in the constellation of Carina, orbiting the star HD 65216. This planet was discovered by the Geneva Extrasolar Planet Search Team in 2003. Like most planet candidates so far, it was detected with the radial velocity method.
HD 83443 b is an extrasolar planet approximately 134 light-years away in the constellation of Vela. It was discovered in 2000 by the Geneva Extrasolar Planet Search Team led by Michel Mayor. It has a minimum mass comparable to Saturn, and its orbit is one of the shortest known, 1/25th that of Earth's. It takes only three days to complete one revolution around the star.
HD 142415 b is an exoplanet with the semi-amplitude of 51.3 ± 2.3 m/s. This indicates the minimum mass of 1.69 Jupiter mass, an orbital period of 386.3 days, and the semi-major axis of 1.07 astronomical units based from its stellar mass. The wild, oval pathed wobble of the star used by Doppler spectrometer indicates that the orbit of the planet is highly eccentric at around 50%.
HD 147513 b is an exoplanet approximately 42 light-years away in the constellation of Scorpius. It is at least 21% more massive than Jupiter. But unlike Jupiter, it orbits the star much closer, mean distance being only a third more than Earth's distance from the Sun. Its orbit is also eccentric; at periastron, it is closer to its star than Earth is from the Sun, whereas at apastron, it is further from its star than Mars to the Sun, finding itself on the outer edge of the habitable zone.
Leonhard Euler Telescope, or the Swiss EULER Telescope, is a national, fully automatic 1.2-metre (47 in) reflecting telescope, built and operated by the Geneva Observatory. It is located at an altitude of 2,375 m (7,792 ft) at ESO's La Silla Observatory site in the Chilean Norte Chico region, about 460 kilometers north of Santiago de Chile. The telescope, which saw its first light on 12 April 1998, is named after Swiss mathematician Leonhard Paul Euler.
