P\u00e4ikeses\u00fcsteem koosneb P\u00e4ikesest ja k\u00f5igist selle \u00fcmber tiirlevatest v\u00e4iksematest taevakehadest. Peale P\u00e4ikese on P\u00e4ikeses\u00fcsteemi suurimad osad kaheksa peamist planeeti. P\u00e4ikesele k\u00f5ige l\u00e4hemal asuvad neli suhteliselt v\u00e4ikest kivist planeeti \u2013 Merkuur, Veenus, Maa ja Marss.<\/p>\n<\/div>\n

Marsist kaugemal asub asteroidi v\u00f6\u00f6 \u2013 piirkond, kus asub miljoneid kiviseid taevakehi. Need on planeetide tekkimise j\u00e4\u00e4gid 4,5 miljardit aastat tagasi.<\/p>\n

Asteroidiv\u00f6\u00f6 teisel pool asuvad neli gaasigiganti \u2013 Jupiter, Saturn, Uraan ja Neptuun. Need planeedid on Maast palju suuremad, kuid oma suurusele vaatamata v\u00e4ga kerged. Nad koosnevad peamiselt vesinikust ja heeliumist.<\/p>\n

Veel hiljuti oli k\u00f5ige kaugem teadaolev planeet j\u00e4\u00e4maailm nimega Pluuto. Pluuto j\u00e4\u00e4b aga Maa Kuu k\u00f5rval t\u00e4iesti varju ning paljud astronoomid leiavad, et see on liiga v\u00e4ike, et seda t\u00f5eliseks planeediks nimetada.<\/p>\n

2005. aastal avastati P\u00e4ikesest v\u00e4ga kaugel objekt nimega Eris, mis on v\u00e4hemalt sama suur kui Pluuto. Viimastel aastatel on Pluuto taga avastatud \u00fcle 1 000 Erisega sarnast j\u00e4ist maailma. Neid nimetatakse Kuiperi v\u00f6\u00f6 objektideks. 2006. aastal otsustas Rahvusvaheline Astronoomia Liit, et Pluuto ja Eris tuleb liigitada \u201ck\u00e4\u00e4busplaneetideks\u201d.<\/p>\n

Veelgi kaugemal asuvad Oorti pilve komeedid. Need on nii kaugel, et neid ei ole n\u00e4ha isegi suurimate teleskoopidega. Aeg-ajalt satub m\u00f5ni neist komeetidest h\u00e4iritud asendisse ja suundub P\u00e4ikese poole. Siis muutub see \u00f6\u00f6taevas n\u00e4htavaks.<\/p>","protected":false},"excerpt":{"rendered":"
