I-Celestia - ukubona ngeso lesikhathi sangempela se-3D sesikhala Ukulingisa kwesikhala samahhala esikuvumela ukuthi uhlole umkhathi wethu ngezilinganiso ezintathu. Ngokungafani nesoftware eminingi yeplanethirium, iCelestia ayikuvaleli ebusweni boMhlaba. Ungahamba kuso sonke isimiso sonozungezilanga, uye kunoma yiziphi izinkanyezi ezingaphezu kuka-100,000, noma nangale komthala. Konke ukunyakaza eCelestia kukhululekile. Isici sokusondeza i-exponential sikuvumela ukuthi uhlole isikhala phakathi kwebanga elikhulu lezikali, kusukela kumaqoqo omthala wehle kuya kumkhumbi-mkhathi ongamamitha ambalwa kuphela ububanzi. Ukusebenzelana kwe-‘point-and-goto’ kwenza kube lula ukuzulazula endaweni yonke uye entweni ofuna ukuyivakashela. I-Celestia iyanwebeka. I-Celestia iza nekhathalogi enkulu yezinkanyezi, imithala, amaplanethi, izinyanga, ama-asteroids, izinkanyezi ezinomsila, nemikhumbi-mkhathi. Uma lokho kungenele, ungalanda inqwaba yezinto ezilula ukuzifaka ngezinto eziningi.
