N\u00fc\u00fcdseks on teada, et Cerese l\u00e4bim\u00f5\u00f5t on umbes 940 km \u2013 ligikaudu veerand (\u00fcks neljandik) Maa Kuu suurusest. Samas moodustab see enam kui veerandi k\u00f5igi asteroide kogumassist.<\/p>\n<\/div>\n

Veel kuusteist asteroidi on l\u00e4bim\u00f5\u00f5duga \u00fcle 240 km. Enamik asteroide on aga vaid m\u00f5ne meetri l\u00e4bim\u00f5\u00f5duga kivid ja r\u00e4ndrahnud. Kui need k\u00f5ik kokku suruda \u00fcheks objektiks, oleks see ikkagi v\u00e4iksem kui Kuu. M\u00f5ned asteroidid on kivised, m\u00f5ned koosnevad metallidest, nagu raud ja nikkel. Enamik neist on must-pruuni v\u00e4rvi ja sisaldavad rohkesti s\u00fcsinikku.<\/p>\n

Paljud asteroidid kuuluvad perekondadesse. Igal perekonnal on sama v\u00e4rvus ja need n\u00e4ivad koosnevat samadest materjalidest. Samuti liiguvad nad peav\u00f6\u00f6 erinevates osades \u00fcksteise l\u00e4hedal. \u00dcks suurimaid neist on Flora-perekond, millel on umbes 400 teadaolevat liiget.<\/p>\n

Asteroide leidub ka peav\u00f6\u00f6 v\u00e4ljaspool. Need on oma kodukohast v\u00e4lja paisatud Jupiteri tugeva gravitatsiooni m\u00f5jul v\u00f5i kokkup\u00f5rgetes teiste asteroididega. M\u00f5ned neist on muutunud hiidplaneedi kuudeks. Sadu tuhandeid asteroide \u2013 sealhulgas ka suuri \u2013 lendavad Maa l\u00e4hedalt m\u00f6\u00f6da.<\/p>","protected":false},"excerpt":{"rendered":"
