    HD 20868 is a star in the southern constellation Fornax. With an apparent visual magnitude of 9.92, it is much too dim to be visible to the naked eye. Parallax measurements give a distance estimate of 156 light years from the Sun. It is drifting further away with a radial velocity of +46.2 km/s, having come to within about 124 ly around 312,000 years ago.

    Pirx (BD+14 4559 b) is an exoplanet orbiting the K-type main sequence star Solaris about 161 light-years (49 parsecs, or nearly 1.5×1015 km) from Earth in the constellation Pegasus. It orbits its star within the habitable zone at a distance of 0.777 AU, close to that of Venus, but its star is less energetic, thus its habitable zone is closer to it than Earth. The exoplanet was found by using the radial velocity method, from radial-velocity measurements via observation of Doppler shifts in the spectrum of the planet's parent star.

    BD+14 4559, named Solaris, is a 10th magnitude K-type main sequence star located approximately 161 light years away in the constellation of Pegasus. On June 10, 2009, an exoplanet (Pirx) was found in orbit by Niedzielski et al. using the Hobby-Eberly Telescope.

    BD+20 2457 is a 10th-magnitude K-type bright giant star located approximately 5,400 light-years away in the constellation of Leo. This star is very metal-poor, containing only 10% as enriched with elements heavier than hydrogen and helium as our sun, almost classifying this as a population II star. On June 10, 2009, two planets were announced to be orbiting the star, with minimum masses 21.4 and 12.5 times the mass of Jupiter and orbital periods of 380 and 622 days for the inner and outer planets, respectively. A dynamical analysis reveals that the proposed system is unstable on astronomically-short timescales and so the suggested planetary configuration is unlikely to be correct: further data is needed to determine a physically-plausible explanation for the radial velocity variations.

    Discoveries of exoplanets Detecting planets located outside the Solar System

    An exoplanet is a planet located outside the Solar System. The first evidence of an exoplanet was noted as early as 1917, but was not recognized as such until 2016. No planet discovery has yet come from that evidence. However, the first scientific detection of an exoplanet began in 1988. Afterwards, the first confirmed detection came in 1992, with the discovery of several terrestrial-mass planets orbiting the pulsar PSR B1257+12. The first confirmation of an exoplanet orbiting a main-sequence star was made in 1995, when a giant planet was found in a four-day orbit around the nearby star 51 Pegasi. Some exoplanets have been imaged directly by telescopes, but the vast majority have been detected through indirect methods, such as the transit method and the radial-velocity method. As of 1 February 2021, there are 4,414 confirmed exoplanets in 3,257 systems, with 722 systems having more than one planet. This is a list of the most notable discoveries.

    HD 240237 b Extrasolar planet

    HD 240237 b is a super-Jupiter exoplanet orbiting the K-type giant star HD 240237 about 4,900 light-years (1,500 parsecs, or nearly 4.6×1016 km) away from Earth in the constellation Cassiopeia. It orbits outside of the habitable zone of its star at a distance of 1.9 AU. The exoplanet was found by using the radial velocity method, from radial-velocity measurements via observation of Doppler shifts in the spectrum of the planet's parent star. The planet has a mildly eccentric orbit.
