V na\u0161om vesm\u00edre je pribli\u017ene 100 mili\u00e1rd galaxi\u00ed. Najv\u00e4\u010d\u0161ie galaxie obsahuj\u00fa temer 400 mili\u00e1rd hviezd. Na\u0161a slne\u010dn\u00e1 s\u00fastava predstavuje len jeden hviezdny syst\u00e9m v r\u00e1mci galaxie mlie\u010dnej dr\u00e1hy. Mlie\u010dna dr\u00e1ha pozost\u00e1va z 300 mili\u00e1rd hviezd.<\/p>\n
Najbli\u017e\u0161ia hviezda Alfa Centauri je vzdialen\u00e1 4,3 sveteln\u00e9ho roka, \u010do je vzdialenos\u0165 meran\u00e1 \u010dasom, za ktor\u00fd k n\u00e1m putuje svetlo.<\/p>\n
Slnko m\u00e1 teplotu jadra 15 mili\u00f3nov stup\u0148ov Celzia a teplotu povrchu 6 000 \u00b0C. Svetlo zo slnka k n\u00e1m putuje 8 min\u00fat, tak\u017ee ak pozorujeme napr. Slne\u010dn\u00e9 erupcie, d\u00edvame sa 8 min\u00fat do minulosti.<\/p>\n
Vek Mesiaca sa odhaduje na 4,6 miliardy rokov. Povrchov\u00e1 teplota Venu\u0161e je dostato\u010dne vysok\u00e1 aj na rozpustenie olova (je to pritom v porad\u00ed druh\u00e1 plan\u00e9ta na\u0161ej s\u00fastavy). Na druhej strane Eur\u00f3pa, jeden z mesiacov Jupitera, m\u00e1 cel\u00fd povrch pokryt\u00fd \u013eadom.<\/p>\n
Pluto je trpasli\u010dia plan\u00e9tka slne\u010dnej s\u00fastavy. V minulosti bola pova\u017eovan\u00e1 za najmen\u0161iu a najvzdialenej\u0161iu plan\u00e9tu slne\u010dnej s\u00fastavy, ale status plan\u00e9ty pred p\u00e1r rokmi stratila a dnes ju ozna\u010dujeme len ako plan\u00e9tku. Pluto obehne Slnko raz za 248 rokov, tak\u017ee jeden rok na Plute je 248 pozemsk\u00fdch.<\/p>\n
