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.
The first extrasolar planet found to have a density compatible with being a rocky planet is CoRoT-7b in 2009. 55 Cancri e was found to be a terrestrial planet in 2011. First super-Earth orbiting a main sequence star [NB 2] Gliese 876 d: Gliese 876: 2005 Orbits a red dwarf star. First icy extrasolar planet orbiting a main sequence star OGLE-2005 ...
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. It is the prototype for a class of planets called hot Jupiters. [4] In 2017, traces of water were discovered in the planet's atmosphere. [5]
WASP-121b, formally named Tylos, [2] is an exoplanet orbiting the star WASP-121. [5] [6] WASP-121b is the first exoplanet found to contain water in an extrasolar planetary stratosphere (i.e., an atmospheric layer in which temperatures increase as the altitude increases). [5] [6] WASP-121b is in the constellation Puppis, [7] and is about 858 ...
The newly discovered exoplanets are 40 light-years away and may contain liquid water. A Belgian-led team made the discovery using both space- and ground-based telescopes, spotting the planets as ...
The study also found that 10 to 20 percent of the exoplanet’s mass comes from water, meaning that the planet is likely a snowball world—with the lone exception of the aforementioned watery ...
