Danes vemo, da ima Ceres premer pribli\u017eno 940 km \u2013 kar je pribli\u017eno ena \u010detrtina velikosti Zemljinega Lune. Vendar pa predstavlja ve\u010d kot eno \u010detrtino skupne mase vseh asteroidov.<\/p>\n<\/div>\n

\u0160e \u0161estnajst asteroidov ima premer ve\u010d kot 240 km. Vendar pa je ve\u010dina asteroidov sestavljena iz kamnov in balvanov, katerih premer zna\u0161a le nekaj metrov. \u010ce bi jih vse stisnili v en sam objekt, bi bil ta \u0161e vedno manj\u0161i od Lune. Nekateri asteroidi so kamniti, drugi pa so sestavljeni iz kovin, kot sta \u017eelezo in nikelj. Ve\u010dina je \u010drno-rjave barve in bogata z ogljikom.<\/p>\n

Mnogi asteroidi pripadajo dru\u017einam. Vsaka dru\u017eina ima enako barvo in je, kot ka\u017ee, sestavljena iz enakih snovi. Poleg tega se gibljejo blizu drug drugega v razli\u010dnih delih glavnega pasu. Ena najve\u010djih med njimi je dru\u017eina Flora, ki \u0161teje pribli\u017eno 400 znanih \u010dlanov.<\/p>\n

Asteroidi se nahajajo tudi zunaj glavnega pasu. Iz svojega izvornega okolja so jih izvrgla mo\u010dna gravitacija Jupitra ali trki z drugimi asteroidi. Nekateri so postali luni tega orja\u0161kega planeta. Sto tiso\u010de asteroidov \u2013 med njimi tudi nekateri veliki \u2013 leti blizu Zemlje.<\/p>","protected":false},"excerpt":{"rendered":"
