Ve\u010dina vesoljskih plovil je ume\u0161\u010denih v orbite okoli Zemlje. Vendar to ni vedno najbolj primerno mesto za znanstvene satelite, ki raziskujejo oddaljeni vesolje.<\/p>\n<\/div>\n

Vesoljski teleskop Hubble kro\u017ei po kro\u017eni orbiti 600 km nad tlemi, ki je nagnjena za 28,5 stopinje glede na ekvator. Ta zemeljska orbita olaj\u0161uje popravila in vzdr\u017eevanje observatorija. Vendar pa Zemlja in Luna zakrivata velike dele neba.<\/p>\n

Hubblov naslednik, vesoljski teleskop James Webb, bo deloval precej dlje stran. Postavljen bo v stabilno orbito na tako imenovani Lagrangeovi to\u010dki L2, ki je oddaljena 1,5 milijona kilometrov na no\u010dni strani Zemlje.<\/p>\n

L2 je ena od petih Lagrangeovih to\u010dk Zemlje. Na teh to\u010dkah se privla\u010dne sile Zemlje, Lune in Sonca medsebojno izni\u010dijo, zato je satelit mogo\u010de brez te\u017eav ohranjati na istem mestu.<\/p>\n

Drugi sateliti, kot je na primer observatorij SOHO agencije ESA, morajo neprestano opazovati Sonce. Ta vesoljsko plovilo se nahaja na Lagrangeovi to\u010dki L1, 1,5 milijona kilometrov od Zemlje v smeri Sonca.<\/p>\n

Ker se gravitacijska sila Zemlje in Sonca na to\u010dki L1 uravnote\u017eita, lahko sonda SOHO ves \u010das lebdi med njima, ne da bi porabljala veliko goriva.<\/p>","protected":false},"excerpt":{"rendered":"
