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]
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
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 ...
The exoplanets were found using a statistical technique called "verification by multiplicity". 95% of the discovered exoplanets were smaller than Neptune and four, including Kepler-296f, were less than 2 1/2 the size of Earth and were in habitable zones where surface temperatures are suitable for liquid water.

A potentially habitable exoplanet that is roughly similar in size to Earth has been found in a system located 40 light-years away, according to a new study.
For the first time ever, scientists announced this week that they have detected an atmosphere around a planet roughly the same size as Earth outside of our solar system, a key factor in the search ...
