Ve\u010dina asteroidov je tako majhnih in tako dale\u010d, da jih lahko vidimo le kot drobne svetle pike. Odkrivamo jih na podlagi njihovega gibanja pred \u2018nepremi\u010dnimi zvezdami\u2019 na no\u010dnem nebu. Ve\u010d o njih izvemo z uporabo velikih teleskopov, s katerimi preu\u010dujemo svetlobo, ki jo odbijajo.<\/p>\n<\/div>\n

Vendar pa niti vesoljski teleskop Hubble ne more veliko razkriti o njih. Eden najbolj zanimivih asteroidov je Vesta, ki je bogata s kovinami. Hubblove slike prikazujejo precej okrogel svet z velikim udarnim kraterjem.<\/p>\n

Nekateri asteroidi, ki letijo blizu Zemlje, so bili preu\u010deni z radarjem. Radarske odmeve zaznavajo veliki radijski teleskopi, na podlagi katerih se ugotavljata njihova oblika in velikost.<\/p>\n

Nekaj asteroidov so vesoljska plovila, ki so jih obiskala, podrobneje preu\u010dila. Slike prikazujejo telesa z mnogimi kraterji, kar ka\u017ee, da so jih v milijardah let pretresali trki. Leta 2000 je sonda NEAR Shoemaker postala prva vesoljska sonda, ki je vstopila v orbito okoli asteroida. Sonda je svojo misijo zaklju\u010dila z zgodovinskim pristankom na Erosu, enem najve\u010djih asteroidov v bli\u017eini Zemlje.<\/p>\n

Vesoljsko plovilo Rosetta agencije ESA je na poti do kometa preletelo tudi dva asteroida iz glavnega pasu \u2013 Steinsa in Lutetio. Lutetia, ki meri v premeru pribli\u017eno 130 km, je bil najve\u010dji asteroid, ki ga je doslej obiskalo vesoljsko plovilo. ESA prav tako preu\u010duje na\u010dine, kako bi lahko odklonila s poti asteroid, ki se pribli\u017euje Zemlji.<\/p>","protected":false},"excerpt":{"rendered":"
