To je bil prvi primer, ko je kdo videl trdno jedro v sredi\u0161\u010du kometa.<\/p>\n<\/div>\n<p>Giottov cilj je bil Halleyjev komet, poimenovan po britanskem astronomu iz 17. stoletja, Edmondu Halleyju. Bil je prvi, ki je ugotovil, da je ta svetel komet reden obiskovalec, ki se v notranji del Oson\u010dja vra\u010da vsakih 75\u201376 let. Njegov naslednji obisk na na\u0161em nebu je predviden za leto 2061.<\/p>\n<p>Halleyjev komet je najbolj znan med milijoni kometov, ki kro\u017eijo okoli Sonca. Tudi ko se nahaja v temi zunanjega Son\u010dnega sistema, Halleyjev komet \u0161e vedno vpliva na na\u0161 planet. Vsako leto oktobra Zemlja pre\u010dka tok drobnega prahu, ki ga je za seboj pustil komet, kar povzro\u010di meteoriti\u010dni roj Orionidov. Domneva se, da je Halleyjev komet odgovoren tudi za meteoriti\u010dni roj Eta Aquarid, ki se pojavi vsako leto v maju. Ti meteori, pogosto znani kot \u201cpadajo\u010de zvezde\u201d, so svetle sledi, ki jih za seboj pu\u0161\u010dajo drobna, hitro lete\u010da zrna kometnih ostankov, ki zgorevajo v Zemljini atmosferi.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"400\" data-credit=\"ESA, image by AOES Medialab\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2011\/05\/Rosetta_orbiting_Comet_67P_Churyumov-Gerasimenko2\" 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\/2011\/05\/rosetta_orbiting_comet_67p_churyumov-gerasimenko2\/18245884-2-eng-GB\/Rosetta_orbiting_Comet_67P_Churyumov-Gerasimenko.jpg\" alt=\"Rosetta orbiting Comet 67P\/Churyumov-Gerasimenko\"><figcaption>Rosetta v orbiti okoli kometa 67P\/\u010curjumov-Gerasimenko<\/figcaption><\/figure>\n<p>Od izjemnega uspeha misije Giotto so vesoljska plovila raziskovala tudi druge komete.
