Teadlased avastasid planeedi, mis hilineb viis minutit – see tundus astronoomidele v\u00e4ga p\u00f5nev, sest see t\u00e4hendab seda, et kuskil l\u00e4hedal asub teinegi planeet.<\/strong><\/p>\n

NASA Kepleri kosmoselaev avastas planeedi, mis j\u00e4\u00e4b oma orbiidil vaheldumisi hiljaks v\u00f5i j\u00f5uab kohale liiga vara, sest teine, ,,n\u00e4htamatu” planeet m\u00f5jutab seda. See on esimene kord, mil varem tundmatu planeet sel viisil otseselt leitud on. \u00dchtegi teist meetodit antud juhul kasutada saanud poleks, kirjutab Sciencedaily.com<\/a>.<\/p>\n

Sel kunstniku poolt kujutatud pildil on ,,n\u00e4htamatu" Kepler-19c n\u00e4ha pildi eesosas. See planeet avastati puhtalt t\u00e4nu selle m\u00f5jule oma kaasplaneedi Kepler-19b(t\u00e4pp t\u00e4he ees) suhtes. Pilt: David A. Aguilar (CfA)<\/p><\/div>\n

Ajaloost on tuntud seik, kus ka Neptuuni olemasolu sarnasel viisil ennustati. ,,See meetod on muidu tabamatute planeetide leidmiseks v\u00e4gagi paljulubav,” s\u00f5nas Harvardi astronoom ja artikli kaasautor David Charbonneau.<\/p>\n

,,See n\u00e4htamatu pklaneet annab endast m\u00e4rku vaid selle j\u00e4rgi, et m\u00f5jutab planeeti, mida me n\u00e4eme,” s\u00f5nas astronoom Sarah Ballard, \u00fcks uurimuse peaautoreid.<\/p>\n

Nii n\u00e4htav kui ka n\u00e4htamatu planeet tiirlevad \u00fcmber P\u00e4ikese-sarnase t\u00e4he Kelper-19, mis asub Maast 650 valgusaasta kaugusel Lyra t\u00e4htkujus. See 12nda suurusj\u00e4rgu t\u00e4ht on septembri\u00f5htute vaatlusteks hea asukohaga.<\/p>\n

Hetkel ei tea astronoomid n\u00e4htamatust Kepler-19c maailmast midagi peale selle, et see eksisteerib. See kaalub liiga v\u00e4he, et selle poolt \u00a0t\u00e4hele m\u00f5juva k\u00fclget\u00f5mbej\u00f5u kaudu selle massi leida. Samuti ei ole Kepler n\u00e4inud seda t\u00e4hest m\u00f6\u00f6dumas, vihjates sellele, et planeedi orbiit on Kepler-19c orbiidi suhtes kaldu.<\/p>\n

,,Kepler-19c’l v\u00f5ib olla mitmeid olemusi, mis on meie andmetega koosk\u00f5las. N\u00e4iteks v\u00f5ib see olla kivine planeet \u00fcmmarguse 5-p\u00e4evase orbiidiga, v\u00f5i gaas-hiidplaneet, mis liigub 100-p\u00e4evasel orbiidil,” s\u00f5nas artikli kaasautor Daniel Fabrycky. Kepleri kosmoselaev j\u00e4tkab Kepler-19 vaatlemist terve oma missiooni jooksul, et teha kindlaks Kepler-19c orbiit. Tulevikus ehitatavad maapinnal asuvad seadmed nagu HARPS-North p\u00fc\u00fcavad teha kindlaks planeedi massi.<\/p>\n
