Vendar ni razloga za zaskrbljenost. Zvezda, vidna s prostim o\u010desom, ni niti pogoltnjena niti umira \u2013 preprosto jo zakriva hitro letajo\u010di asteroid.<\/p>\n<\/div>\n<p>Ta majhen ko\u0161\u010dek kamnine, znan kot (472) Roma, bo nekaj sekund na pravem mestu ob pravem \u010dasu, da bo zasen\u010dil zvezdno svetlobo, ki prihaja na Zemljo. To je redek dogodek \u2013 edini v tem stoletju, ko bo mogo\u010de brez daljnogleda ali teleskopa opazovati, kako asteroid zakrije zvezdo.<\/p>\n<p>Vsi poznamo son\u010dev mrk, ko Luna preide pred Soncem in se nebo za nekaj minut potemni. \u010ceprav je Luna 400-krat manj\u0161a od Sonca, je tudi 400-krat bli\u017eje, zato lahko zakrije celoten disk na\u0161e najbli\u017eje zvezde.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"364\" data-credit=\"NASA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2010\/07\/A_grazing_occultation_of_Rhea_a_moon_of_Saturn_by_another_moon_Dione2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2010\/07\/a_grazing_occultation_of_rhea_a_moon_of_saturn_by_another_moon_dione2\/17872928-2-eng-GB\/A_grazing_occultation_of_Rhea_a_moon_of_Saturn_by_another_moon_Dione.jpg\" alt=\"A grazing occultation of Rhea, a moon of Saturn, by another moon, Dione\"><figcaption>Prekrivanje lune Rhea, ene od Saturnovih lun, s strani druge lune, Dione<\/figcaption><\/figure>\n<p>Enako se lahko zgodi tudi z bolj oddaljenimi zvezdami. Asteroid s premerom 50 km, kot je Roma, lahko za kratek \u010das zakrije ogromno zvezdo, kot je Delta Ophiuchi, saj je ta vesoljska skala veliko bli\u017eje nam. Tak\u0161ni dogodki so pomembni, saj astronomom omogo\u010dajo, da dolo\u010dijo velikost in obliko asteroidov \u2013 vklju\u010dno s tistimi, ki bi neko\u010d lahko tr\u010dili v Zemljo.<\/p>\n<p>Zvezdino izginotje bo mogo\u010de opaziti le s pribli\u017eno 50 km \u0161irokega pasu, ki povezuje Stockholm, Kopenhagen, Bremen, Nantes, Bilbao in Kanarske otoke. Do tega bo pri\u0161lo okoli 23:57 po srednjeevropskem poletnem \u010dasu (CEST), \u010deprav se bo natan\u010den \u010das od kraja do kraja razlikoval.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1008\" data-credit=\"Credits: ESA, created with Guide 8 by Project Pluto http:\/\/www.projectpluto.com\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2010\/07\/Star_chart_showing_the_sky_from_central_Europe2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2010\/07\/star_chart_showing_the_sky_from_central_europe2\/18249399-2-eng-GB\/Star_chart_showing_the_sky_from_central_Europe.jpg\" alt=\"Star chart showing the sky from central Europe\"><figcaption>Zvezdna karta, ki prikazuje nebo iz srednje Evrope<\/figcaption><\/figure>","protected":false},"excerpt":{"rendered":"<p>On 8 July, a fairly bright star, known as Delta Ophiuchi, will disappear from the night sky.
