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 ...
* Gas giant likely has no surface, liquid water if present could only be on a large satellite (none known) * density implies water in atmosphere, but none found yet * Possible class II ("water cloud") or class III ("clear") atmosphere planet [12] Gliese 581 c [citation needed] Gliese 581: 5.5 700–1000 20 7–11 12.9 2007 * Not in the CHZ
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 star 51 Pegasi b: 51 Pegasi: 1995 First convincing exoplanet discovered around a Sun-like star. [2]
This list contain only confirmed planets. Many candidate planets were decected via astrometry, including Gliese 65 Ab (which would be the nearest planet detected by this method, if confirmed), 9,698 candidates shown in a paper [1] as well as many more detected via Hipparcos-Gaia astrometry in another studies.
The newly discovered exoplanets are 40 light-years away and may contain liquid water. ... "This is the first time that so many planets of this kind are found around the same star," continued ...
Also known as a 'hot Jupiter,' the exoplanet is so close to its star that temperatures at the top of the planet could even boil some metals. Scientists find new exoplanet with atmosphere of ...
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.
While hot, that temperature is lower than most of the thousands of exoplanets discovered to date. “Gliese 12 b could be at the right temperature for liquid water to pool on its surface, ...
