Enaiposha , also hump as GJ 1214 b , is an exoplanet orbiting the red dwarf Orkaria , settle just 48 light - years from the Solar System . It was discovered in 2009 and was one of the first exoplanets to have both its good deal and radius measure . It is bigger than Earth but a lot smaller than Neptune , so it has been refer to as either a A-one - globe or a mini - Neptune , as their difference are more insidious than just size . New enquiry suggest that maybe a unlike class totally is needed , as this world could be defined as a " topnotch - Urania " .
Enaiposha is one of the few exoplanets with a right name , givenin 2022by a squad in Kenya after theMaa wordfor with child body of pee because it was considered a probable weewee world . The exoplanet has been observe byJWST , with the telescope using its keen middle to analyze Enaiposha ’s atmosphere . That information is now out , and paints a very different film .
The observation did not show a major front of hydrogen , as would be await if the planet had an atmosphere more similar to the accelerator pedal giants . It also did not show the presence of weewee . The observations propose the presence of haze and an standard atmosphere rich in heavy factor , with a strong signal point carbon dioxide .
Venusis Earth ’s sizing , but it has a dramatically different atmosphere : It ’s a mickle thicker and mostly ( 96.5 percentage ) carbon dioxide . So the team suggests that this exoplanet might be like a scaled - up reading of Venus .
Two papers show these challenging signal , but the team stress that there are currently many uncertainties to corroborate that this is indeed a super - genus Venus . While being so unaired to the Sun has helped hit the books this major planet , Enaiposha ’s atmosphere has been a challenge to fully characterise .
“ It ’s equivalent to Leo Tolstoy ’s War and Peace . If I gave you two copies and alter one sentence in one of the books , could you find that time ? ” hint author of one bailiwick Everett Schlawin , from the University of Arizona and the Steward Observatory , said in astatement .
“ The detected CO2signal from the first bailiwick is midget , and so it need thrifty statistical depth psychology to guarantee that it is real , ” explained the steer author of the other study Kazumasa Ohno , from the National Astronomical Observatory of Japan . “ At the same time , we needed the physical and chemical perceptiveness to extract the dependable nature of GJ 1214 b ’s atmosphere from Schlawin ’s report . ”
