Sonda Rosetta agencije ESA, ki sledi kometom, se odpravlja na slepo zmenko z asteroidom Lutetia. Kot pri mnogih prvih zmenkih se bo Rosetta s Lutetio sre\u010dala v soboto zve\u010der. Vendar pa \u0161e nih\u010de ne ve, kako Lutetia izgleda od blizu. Verjetno bo povr\u0161ina Lutetie zelo stara in prekrita s kraterji, saj so asteroidi ko\u0161\u010dki kamnine, ki so ostali po nastanku planetov.<\/p>\n<\/div>\n

O tem skrivnostnem \u010dlanu glavnega asteroidnega pasu, ki kro\u017ei okoli Sonca med Marsom in Jupitrom, je znanega le malo. Vendar je Lutetia vsekakor najve\u010dji asteroid, ki ga je doslej obiskalo vesoljsko plovilo. Sprva so menili, da ima premer okoli 95 km, vendar je le rahlo elipti\u010dna (v obliki jajca). Novej\u0161e ocene ka\u017eejo, da je morda precej bolj podolgovat in \u0161irok do 134 km. Nenehne spremembe njegove svetlosti jasno ka\u017eejo, da se Lutetia vrti in ima hrapavo povr\u0161ino.<\/p>\n

\u0160e ena uganka se nana\u0161a na sestavo asteroida. Ve\u010dina meritev ka\u017ee, da gre za asteroid \u2018tipa C\u2019, ki vsebuje ogljikove spojine. Vendar nekatere \u0161tudije nakazujejo, da bi lahko \u0161lo za asteroid \u2018tipa M\u2019, ki je bogat s kovinami.<\/p>\n

Odgovori na vsa ta vpra\u0161anja bodo znani, ko se bo sonda Rosetta 10. julija pribli\u017eala vesoljskemu telesa na razdaljo 3.200 km. Kontrolorji na Zemlji skrbno prilagajajo pot sonda, da bo ta lahko poslala nazaj pribli\u017eno dve uri podrobnih posnetkov. Sond bo takoj za\u010dela po\u0161iljati podatke nazaj na Zemljo, prve slike pa bodo objavljene \u0161e isti ve\u010der. Rosetta se bo nato odpravila na \u0161e eno prvo sre\u010danje \u2013 tokrat s kometom \u010curjumov-Gerasimenko \u2013, pri \u010demer je to vznemirljivo sre\u010danje predvideno za leto 2014.<\/p>","protected":false},"excerpt":{"rendered":"
