Astronomii au identificat o nou\u0103 planet\u0103 de dimensiunea P\u0103m\u00e2ntului, aflat\u0103 la aproximativ 146 de ani-lumin\u0103 distan\u021b\u0103, care ar putea fi situat\u0103 \u00een zona locuibil\u0103 a stelei sale, anun\u021b\u0103 TheGuardian<\/a><\/span>.<\/p>\n

Planeta, numit\u0103 HD 137010 b, este considerat\u0103 un candidat promi\u021b\u0103tor pentru studii viitoare, de\u0219i oamenii de \u0219tiin\u021b\u0103 avertizeaz\u0103 c\u0103 temperaturile de la suprafa\u021b\u0103 ar putea fi extrem de sc\u0103zute.<\/p>\n

Descoperirea se \u00eenscrie \u00een eforturile tot mai intense de a identifica lumi apropiate care ar putea sus\u021bine via\u021ba.<\/p>\n

O lume apropiat\u0103, de dimensiunea P\u0103m\u00e2ntului, cu o orbit\u0103 familiar\u0103<\/h2>\n

HD 137010 b orbiteaz\u0103 o stea similar\u0103 Soarelui \u0219i este estimat\u0103 a fi cu doar \u0219ase procente mai mare dec\u00e2t P\u0103m\u00e2ntul.<\/p>\n

Potrivit cercet\u0103torilor, planeta finalizeaz\u0103 o orbit\u0103 \u00een aproximativ 355 de zile, un ciclu foarte apropiat de anul terestru.<\/p>\n

Oamenii de \u0219tiin\u021b\u0103 estimeaz\u0103 c\u0103 exist\u0103 o probabilitate de circa 50% ca planeta s\u0103 se afle \u00een zona locuibil\u0103, unde apa lichid\u0103 ar putea exista teoretic.<\/p>\n

Planeta a fost identificat\u0103 folosind date colectate de telescopul spa\u021bial Kepler al NASA, \u00een cadrul misiunii sale extinse K2, \u00een anul 2017.<\/p>\n

Detectarea a avut loc atunci c\u00e2nd planeta a trecut prin fa\u021ba stelei sale, provoc\u00e2nd o sc\u0103dere u\u0219oar\u0103, dar m\u0103surabil\u0103, a luminozit\u0103\u021bii.<\/p>\n

\u0218tiin\u021b\u0103 \u0219i verific\u0103ri riguroase<\/h2>\n

Semnalul ini\u021bial a fost observat pentru prima dat\u0103 de voluntari din cadrul proiectului de \u0219tiin\u021b\u0103 cet\u0103\u021beneasc\u0103 Planet Hunters.<\/p>\n

Unul dintre participan\u021bi a devenit ulterior autorul principal al studiului, subliniind rolul tot mai important al publicului \u00een cercetarea astronomic\u0103.<\/p>\n

Cercet\u0103torii spun c\u0103 semnalul a fost verificat cu aten\u021bie pentru a elimina eventualele erori.<\/p>\n

Cu toate acestea, p\u00e2n\u0103 \u00een prezent a fost observat un singur tranzit planetar, ceea ce \u00eenseamn\u0103 c\u0103 sunt necesare observa\u021bii suplimentare pentru confirmarea complet\u0103 a statutului planetei.<\/p>\n

Temperaturile sc\u0103zute \u0219i observa\u021biile viitoare<\/h2>\n

De\u0219i dimensiunea \u0219i orbita planetei sunt promi\u021b\u0103toare, steaua pe care o orbiteaz\u0103 este mai rece \u0219i mai pu\u021bin luminoas\u0103 dec\u00e2t Soarele.<\/p>\n

Din acest motiv, temperaturile de la suprafa\u021ba lui HD 137010 b ar putea cobor\u00ee sub minus 70 de grade Celsius, f\u0103c\u00e2nd-o mai asem\u0103n\u0103toare cu o lume \u00eenghe\u021bat\u0103, de tip mar\u021bian.<\/p>\n

Astronomii consider\u0103 c\u0103 distan\u021ba relativ mic\u0103 fa\u021b\u0103 de P\u0103m\u00e2nt face din aceast\u0103 planet\u0103 o \u021bint\u0103 ideal\u0103 pentru telescoapele de genera\u021bie urm\u0103toare.<\/p>\n

Observa\u021biile viitoare ar putea stabili dac\u0103 este vorba despre o planet\u0103 st\u00e2ncoas\u0103, asem\u0103n\u0103toare P\u0103m\u00e2ntului, sau despre o \u201esuper-bulg\u0103re de ghea\u021b\u0103\u201d, dominat\u0103 de ap\u0103 \u00eenghe\u021bat\u0103.<\/p>\n
