Despite completing its orbit in just 12.8 days due to its proximity to its star, <strong>the surface temperature of the exoplanet is estimated at 42 degrees Celsius<\/strong>, assuming it has no atmosphere.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;This is the closest world, in transit, temperate and the <a href=\"https:\/\/en.softonic.com\/articles\/they-discover-a-planet-the-size-of-earth-orbiting-an-ultra-cold-red-dwarf\" target=\"_blank\" rel=\"noopener\" title=\"\">size of Earth<\/a> located to date,&#8221; said <strong>Masayuki Kuzuhara<\/strong>, professor at the Tokyo Center for Astrobiology and co-leader of one of the research teams. The discovery was made using public data collected by the <strong>NASA&#8217;s TESS satellite<\/strong>, which observes the brightness of tens of thousands of stars each month, in search of transiting exoplanets.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Larissa Palethorpe<\/strong>, a PhD student at the University of Edinburgh and University College London, highlighted the importance of the discovery due to <strong>the relative proximity of the exoplanet<\/strong>. This finding allows scientists to analyze the atmosphere of Gliese 12b to <strong>determine if it contains crucial elements for life, such as water<\/strong>. &#8220;We have only found a handful of exoplanets that are good candidates for this. And this is the closest one,&#8221; Palethorpe pointed out.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/articles-img.sftcdn.net\/sft\/articles\/auto-mapping-folder\/sites\/3\/2024\/05\/Comparacion-Tierra-Gliese-12b-1024x576-1-1024x576.jpg\" alt=\"\" class=\"wp-image-282089\" srcset=\"https:\/\/articles-img.sftcdn.net\/auto-mapping-folder\/sites\/3\/2024\/05\/Comparacion-Tierra-Gliese-12b-1024x576-1-1024x576.jpg 1024w, https:\/\/articles-img.sftcdn.net\/auto-mapping-folder\/sites\/3\/2024\/05\/Comparacion-Tierra-Gliese-12b-1024x576-1-300x169.jpg 300w, https:\/\/articles-img.sftcdn.net\/auto-mapping-folder\/sites\/3\/2024\/05\/Comparacion-Tierra-Gliese-12b-1024x576-1-768x433.jpg 768w, https:\/\/articles-img.sftcdn.net\/auto-mapping-folder\/sites\/3\/2024\/05\/Comparacion-Tierra-Gliese-12b-1024x576-1-800x450.jpg 800w, https:\/\/articles-img.sftcdn.net\/auto-mapping-folder\/sites\/3\/2024\/05\/Comparacion-Tierra-Gliese-12b-1024x576-1-664x374.jpg 664w, https:\/\/articles-img.sftcdn.net\/auto-mapping-folder\/sites\/3\/2024\/05\/Comparacion-Tierra-Gliese-12b-1024x576-1-238x134.jpg 238w, https:\/\/articles-img.sftcdn.net\/auto-mapping-folder\/sites\/3\/2024\/05\/Comparacion-Tierra-Gliese-12b-1024x576-1-436x246.jpg 436w, https:\/\/articles-img.sftcdn.net\/auto-mapping-folder\/sites\/3\/2024\/05\/Comparacion-Tierra-Gliese-12b-1024x576-1-370x208.jpg 370w, https:\/\/articles-img.sftcdn.net\/auto-mapping-folder\/sites\/3\/2024\/05\/Comparacion-Tierra-Gliese-12b-1024x576-1-304x170.jpg 304w, https:\/\/articles-img.sftcdn.net\/auto-mapping-folder\/sites\/3\/2024\/05\/Comparacion-Tierra-Gliese-12b-1024x576-1.jpg 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">However, the presence of water on Gliese 12b is still uncertain. Palethorpe mentioned that <strong>there may not be any water<\/strong>, which would imply a runaway greenhouse effect similar to that of Venus. The next phase of the study will use the <strong><a href=\"https:\/\/en.softonic.com\/articles\/the-james-webb-telescope-has-discovered-the-original-stars-of-the-universe\" target=\"_blank\" rel=\"noopener\" title=\"\">James Webb Space Telescope<\/a><\/strong> to perform spectroscopic analysis, which would <strong>capture starlight through the exoplanet&#8217;s atmosphere<\/strong> and determine the presence of certain molecules.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This finding not only sheds light on Gliese 12b, but also <strong>provides clues about the conditions that allowed Earth to remain habitable<\/strong> while Venus did not. According to Palethorpe, this exoplanet could help us better understand the pathways to habitability that planets take as they evolve.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Despite the potential interest, <strong>a manned mission to Gliese 12b is currently unfeasible<\/strong>. As Palethorpe pointed out, the exoplanet is &#8220;12 parsecs&#8221; away, which would mean <strong>a journey of approximately 225,000 years with the fastest spacecraft we have today<\/strong>.<\/p>\n\n\n<div class=\"sc-card-program\">\r\n  <div class=\"sc-card-program__body\">\r\n    <div class=\"sc-card-program__row clearfix\">\r\n      <div class=\"sc-card-program__col-logo\">\r\n        <img decoding=\"async\" class=\"sc-card-program__img\" alt=\"NASA App\" src=\"https:\/\/images.sftcdn.net\/images\/t_app-icon-s\/p\/2cddcc48-a4d6-11e6-88af-00163ec9f5fa\/3678680588\/nasa-app-logo\" width=\"100px\" height=\"100px\">\r\n      <\/div>\r\n      <div class=\"sc-card-program__col-title\">\r\n        <span class=\"sc-card-program__title\">NASA App<\/span>\r\n        <a class=\"sc-card-program__button sc-card-program-internal\" href=\"https:\/\/nasa-app.en.softonic.com\/android\" target=\"_self\" rel=\"noopener noreferrer\">DOWNLOAD<\/a>\r\n      <\/div>\r\n      <div class=\"sc-card-program__col-rating\">\r\n        <svg class=\"rating-score__content\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" version=\"1.1\" x=\"0\" y=\"0\" viewbox=\"0 0 50 50\" enable-background=\"new 0 0 50 50\" xml:space=\"preserve\"><path class=\"rating-score__background rating-score--good\" fill=\"none\" stroke-width=\"6\" stroke-miterlimit=\"10\" d=\"M40 40c8.3-8.3 8.3-21.7 0-30s-21.7-8.3-30 0 -8.3 21.7 0 30\"><\/path><path class=\"rating-score__value rating-score__value--0\" fill=\"none\" stroke-width=\"6\" stroke-dashoffset=\"0\" stroke-miterlimit=\"10\" d=\"M40 40c8.3-8.3 8.3-21.7 0-30s-21.7-8.3-30 0 -8.3 21.7 0 30\"><\/path><text class=\"rating-score__number\" content=\"\" text-anchor=\"middle\" transform=\"matrix(1 0 0 1 25 31.0837)\" data-auto=\"app-user-score\"><\/text><\/svg>\r\n      <\/div>\r\n    <\/div>\r\n    <div class=\"sc-card-program__row\">\r\n      <span class=\"sc-card-program__description\"><\/span>\r\n    <\/div>\r\n    <div class=\"sc-card-program__row\">\r\n      <img decoding=\"async\" class=\"sc-card-program__bigpic\" src=\"\" onerror=\"this.style.display='none'\">\r\n    <\/div>\r\n    <a class=\"sc-card-program__link track-link sc-card-program-internal\" href=\"https:\/\/nasa-app.en.softonic.com\/android\" target=\"_self\" rel=\"noopener noreferrer\"><\/a>\r\n  <\/div>\r\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Two teams of scientists have identified a potentially habitable planet located about 40 light-years from Earth.
