A Pl\u00fat\u00f3t 1930-ban fedezte fel a 24 \u00e9ves Clyde Tombaugh, aki egy speci\u00e1lis k\u00e9sz\u00fcl\u00e9k seg\u00edts\u00e9g\u00e9vel hasonl\u00edtotta \u00f6ssze az \u00e9gboltr\u00f3l k\u00e9sz\u00fclt f\u00e9nyk\u00e9peket. Kider\u00fclt, hogy egy apr\u00f3cska \u00e9gitestr\u0151l van sz\u00f3, amely m\u00e9g a Holdunkn\u00e1l is kisebb.<\/p>\n<\/div>\n

A Pl\u00fat\u00f3 elliptikus (toj\u00e1s alak\u00fa) p\u00e1ly\u00e1n kering, amelynek t\u00e1vols\u00e1ga 7 381 milli\u00f3 km (49 Nap\u2013F\u00f6ld t\u00e1vols\u00e1g) \u00e9s 4 446 milli\u00f3 km (30 Nap\u2013F\u00f6ld t\u00e1vols\u00e1g) k\u00f6z\u00f6tt v\u00e1ltozik. Mivel egy teljes k\u00f6rbej\u00e1r\u00e1s 248 \u00e9vig tart, a Pl\u00fat\u00f3n sz\u00fcletett senki sem \u00fcnnepelhetne soha egyetlen sz\u00fclet\u00e9snapot sem!<\/p>\n

Pl\u00fat\u00f3r\u00f3l nagyon keveset tudunk. Felsz\u00edne rendk\u00edv\u00fcl hideg (-230 \u00b0C), \u00e9s \u00fagy t\u0171nik, hogy befagyott j\u00e9gr\u00e9teg bor\u00edtja. Az elm\u00falt \u00e9vekben viszonylag k\u00f6zel volt a Naphoz, \u00e9s egy r\u00f6vid nyarat \u00e9lvezett. A felsz\u00edni j\u00e9g elp\u00e1rolgott, \u00e9s v\u00e9kony l\u00e9gk\u00f6rt hozott l\u00e9tre. Most azonban a Naprendszer hideg m\u00e9ly\u00e9be h\u00faz\u00f3dik vissza, \u00e9s ez a l\u00e9gk\u00f6r hamarosan \u00fajra megfagy.<\/p>\n

A Pl\u00fat\u00f3 6 nap 9 \u00f3ra alatt egyszer \u201cford\u00edtva\u201d (keletr\u0151l nyugatra) forog. Legnagyobb holdja, a Charon, ugyanennyi id\u0151 alatt ker\u00fcli meg a Pl\u00fat\u00f3t. Ez azt jelenti, hogy aki a Pl\u00fat\u00f3 egyik oldal\u00e1n \u00e9l, soha nem l\u00e1thatja a Charont. A Hubble \u0170rt\u00e1vcs\u0151 seg\u00edts\u00e9g\u00e9vel nemr\u00e9g k\u00e9t kisebb holdat is felfedeztek.<\/p>\n

Hossz\u00fa \u00e9vekig Pl\u00fat\u00f3t a Napt\u00f3l sz\u00e1m\u00edtott kilencedik bolyg\u00f3nak tekintett\u00e9k (annak ellen\u00e9re, hogy n\u00e9ha k\u00f6zelebb ker\u00fcl a Naphoz, mint a Neptunusz). Ma m\u00e1r \u201ct\u00f6rpebolyg\u00f3nak\u201d sz\u00e1m\u00edt. Emellett a Kuiper-\u00f6v egyik legnagyobb tagja is, amely a Neptunuszon t\u00fali t\u00e9rs\u00e9get elfoglal\u00f3, jeges \u00e9gitestek csoportja.<\/p>","protected":false},"excerpt":{"rendered":"
