First detected exoplanet later confirmed Gamma Cephei Ab: Gamma Cephei: 1988 (suspected), 2002 (confirmed) First evidence for exoplanet to receive later confirmation. First exoplanets to be confirmed PSR B1257+12 B PSR B1257+12 C: PSR B1257+12: 1992 First super-Earths. [1] These exoplanets orbit a pulsar. First confirmed exoplanet around normal ...
51 Pegasi b, officially named Dimidium / d ɪ ˈ m ɪ d i ə m /, is an extrasolar planet approximately 50 light-years (15 parsecs) away in the constellation of Pegasus.It was the first exoplanet to be discovered orbiting a main-sequence star, [3] the Sun-like 51 Pegasi, and marked a breakthrough in astronomical research.
51 Pegasi b: In 1995 this became the first exoplanet orbiting a main-sequence star to have its existence confirmed.It is a hot Jupiter with a 4.2-day orbit. [12]47 Ursae Majoris b: In 1996 this Jupiter-like planet was the first long-period planet discovered, orbiting at 2.11 AU from the star with the eccentricity of 0.049.
Gamma Cephei Ab (abbreviated γ Cephei Ab, γ Cep Ab), formally named Tadmor / ˈ t æ d m ɔːr /, is an exoplanet approximately 45 light-years away in the constellation of Cepheus (the King). The planet was confirmed to be in orbit around Gamma Cephei A in 2003, but was first suspected to exist around 1988 (making this planet arguably the ...
An F-type star KOI-4 was among the observed exoplanetary system. Before 2009, KOI-1 to KOI-3 were already known as possible exoplanet bearing stars. [14] KOI-4.01 was thus the first exoplanet identified by the Kepler spacecraft. [5] [15] KOI-4.01 was seen as blocking a bit of starlight from the KOI-4, which indicated that it was a transiting ...
On December 18, 2014, NASA announced that the K2 mission had detected its first confirmed exoplanet, a super-Earth named HIP 116454 b. Its signature was found in a set of engineering data meant to prepare the spacecraft for the full K2 mission. Radial velocity follow-up observations were needed as only a single transit of the planet was detected.
Kepler-9b's name denotes that it is the first exoplanet discovered in orbit around the star Kepler-9. The star, in turn, was named for the Kepler Mission, a NASA project designed to search for Earth-like planets. [5] Kepler-9's planets were among 700 planetary candidates collected during Kepler's first 43 days online.
Kepler-9c is one of the first seven extrasolar planets, exoplanets, discovered by NASA's Kepler Mission, and one of at least two planets orbiting the star Kepler-9.Kepler-9c and Kepler-9b were the first exoplanets confirmed to be transiting their star.
