I-Celestia-ixesha lokwenyani lokubonwa kwe-3D yendawo Ukulinganisa indawo yasimahla ekuvumela ukuba uphonononge indalo yethu kumacala amathathu. Ngokungafaniyo noninzi lwesoftware yeplanethi, iCelestia ayikuvaleli kumphezulu woMhlaba. Unokuhamba kuzo zonke izijikelezi-langa, ukuya kuyo nayiphi na iinkwenkwezi ezingaphezu kwe-100,000, okanye nangaphaya komnyele. Yonke intshukumo eCelestia ayinamthungo. Inqaku lokwandisa i-exponential likuvumela ukuba ujonge indawo kuluhlu olukhulu lwezikali, ukusuka kumaqela omnyele ukuhla ukuya kwiziphekepheke kumgama nje weemitha ezimbalwa ukunqumla. I-interface ye-'point-and-goto' yenza kube lula ukuzulazula kwindalo yonke ukuya kwinto ofuna ukuyindwendwela. ICelestia inokwandiswa. I-Celestia iza nekhathalogu enkulu yeenkwenkwezi, iminyele, iiplanethi, iinyanga, ii-asteroids, ii-comets kunye ne-spacecraft. Ukuba oko akwanelanga, unokukhuphela ezininzi lula ukufaka izongezo kunye nezinto ezininzi.
