From NASA\u2019s retired Kepler Space Telescope data, an international science team has found a candidate exoplanet that is similar to Earth but way cooler \u2014 even cooler than Mars. The candidate planet is called HD 137010 b. <\/p>\n
HD 137010 b is possibly a rocky planet that orbits a Sun-like star about 146 light-years away. It likely takes it around one year to orbit its star just like Earth. From the findings, the HD 137010 b is likely to fall just within the outer edge of the star\u2019s habitable zone. This orbital distance could still allow liquid water to form on the candidate planet\u2019s surface under a suitable atmosphere. The science team\u2019s models suggest that HD 137010 b has a 40% chance of falling within the \u201cconservative\u201d habitable zone and a 51% chance of falling within the broader \u201coptimistic\u201d habitable zone. But the authors of the study say that the planet has a 50-50 chance of falling beyond the habitable zone entirely. <\/p>\n
HD 137010 b\u2019s Sun is similar to Earth\u2019s, but unlike Earth\u2019s Sun, it is cooler and dimmer. As a result, the planet would only receive one-third of the heat and light that Earth receives. This is why the expected temperature on HD 137010 b is no higher than minus 90\u00b0 Fahrenheit \u2014 much cooler than Mars\u2019s minus 85\u00b0 Fahrenheit temperature. At that temperature, finding liquid water on HD 137010 b would be highly unlikely except that it has an atmosphere richer in carbon dioxide than Earth. <\/p>\n
The researchers\u2019 discovery comes from a single transit. A transit is a period where a planet\u2019s shadow moves across a star, dimming the star\u2019s light. For HD 137010 b, its transit lasted 10 hours. Studying that single transit qualified HD 137010 b to be considered a candidate planet. Scientists will dig further to confirm whether it is truly a planet.<\/p>\n","protected":false},"excerpt":{"rendered":"From NASA\u2019s retired Kepler Space Telescope data, an international science team has found a candidate exoplanet that is…\n","protected":false},"author":2,"featured_media":337843,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[77],"tags":[582,1820,18,1821,157706,19,17,1815,1819,1814,1822,1818,1142,1143,133,1817,1816],"class_list":["post-337842","post","type-post","status-publish","format-standard","has-post-thumbnail","category-science","tag-astronomy","tag-benchmarks","tag-eire","tag-graphics-card","tag-hd-137010-b","tag-ie","tag-ireland","tag-laptop","tag-netbook","tag-notebook","tag-processor","tag-reports","tag-review","tag-reviews","tag-science","tag-test","tag-tests"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ie\/116071634305352857","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/337842","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=337842"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/337842\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/337843"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=337842"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=337842"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=337842"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
