Ulwazi olukhululekileyo njengelanga le-star, kwiplanethi yethu epheleleyo kunye nobani na ojonge phezulu kwihlabathi elunxwemeni.
Phambi kokuba sihambe, bona apho ukhona. Uhlala kwithayile encinci, emanzi, ijikeleza ngokukhawuleza kunesandi kwaye iwela ngokusisigxina phantsi kwelanga eliqhelekileyo. Intsimbi kwigazi lakho ne calcium kwimithambo yakho zakwenziwa kwiintlanzi ezifa phambi kokuba ilanga lizalwa. Kwixesha elizayo siya kubaleka ngaphandle, ngexabiso elipheleleyo, ngaphezulu kwehlabathi elibelana ngokukhanya kwethu. Inqwelo- moya enkulu yimnyama; leyo yinto. Gcina ingqalelo kwinto enqamlezeneyo eluhlaza okwesibhakabhaka ngasemva kwakho. Yindawo kuphela esiyazi apho umntu othile wajonge phezulu kwaye abuze.
Ilanga
Zonke izinto ziqala apha. Ilanga ligcina i-99.86% yesisindo senkqubo yelanga: i-fusion reactor eneeplanethi ezili-109 zehlabathi.

Ingxenye yobungakanani behlabathi, kunye nokuzama kwelanga okujika kube luhlaza. Ihlabathi elilandelayo abantu bacwangcisa ukuhamba kuyo.
Ukusuka kwilanga: 1.5 AU · Ukukhanya kwelanga: 12.7 min · Imini enye iphela: 24.7 h · -65 °Cunit-format
Ingaphezulu kwesibini kunaleyo yezinye iiplanethi zonke zidityanisiwe. I-Great Red Spot yayo yimvula ebanzi kunehlabathi.
Ukusuka kwilanga: 5.2 AU · Ukukhanya kwelanga: 43.3 min · Imini enye iphela: 9.9 h · -110 °Cunit-format
Iiringi ezibanzi kune-270,000 km kwaye, kwiindawo, malunga nemitha ezilishumi ziqinile. ISaturn ayiqhelekanga kakhulu kunamanzi.
Ukusuka kwilanga: 9.5 AU · Ukukhanya kwelanga: 1 h 19 min · Imini enye iphela: 10.7 h · -140 °Cunit-format
Tipped over at 98 degrees, it rolls around the Sun. Each pole gets 42 years of daylight, then 42 of night.
Ukusuka kwilanga: 19.2 AU · Ukukhanya kwelanga: 2 h 40 min · Imini enye iphela: 17.2 h · -195 °Cunit-format
Iimoya eziya kwi 2000 km/ h, ezikhawulezayo kwinkqubo yelanga. Kusuka apha ilanga liyona nto ikhanyayo kuphela kwisibhakabhaka esimnyama.
Ukusuka kwilanga: 30.1 AU · Ukukhanya kwelanga: 4 h 10 min · Imini enye iphela: 16.1 h · -200 °Cunit-format
You have just crossed 4.5 billion kilometres. Sunlight makes the same journey in about four hours, and it has been making it for four and a half billion years.
Funda indlela i-orbit esebenza ngayoZonke iingxaki emhlabeni, ziyingxaki yolwazi. Sichaza isayensi ecaleni kweengozi ezibangelwa yikhaya lethu linye, sifundisa ubunzulu bomhlaba kubo bonke abajongeyo, kwaye sixhasa konke oku ngokuvulekileyo. Akukho mngxuma wokuhlawula. Akukho baqeshi bemali. Kuphela ukufuna ukwazi, obhekiswe kwixesha elizayo.
Iindlela ezine zokukhathalela iplanethi encinci: iilwandle zayo kunye nomoya, amandla ayo, umgangatho wokuphila okuphilayo kuyo, kunye negumbi lokufunda elivulekileyo kulowo nalowo ofuna ukufinyelela ngaphezulu kwayo.
Iikhosi kunye neezixhobo ezisebenza ngokudibanisa eziguqula wonke umntu waba ngumntu oqondayo ii-orbit, iiroketi nezoqoqosho zesithuba. Zikhululekile, ubomi bonke.

Kwimbali yomhlaba wonke, umntu ngamnye wayekwazi ukujonge phezulu kwaye afumane iNdlela yeMilk. Namhlanje umntu omnye kwisibini akazange abone loo ndlela, kwaye abasibhozo kwishumi baphila phantsi kwelanga elingaziyo ukuba limnyama ngaye. Unyango lulula: ukhusele ukukhanya, uyenze ibe mdaka, uze uyishiye imini ibuye xa akukho namnye ofuna ukuyibona.

Uguqulelo lwesifundo, ujonge ifizikhi, yenza isixhobo, ucwangcise umhla wezulu elimnyama. Yonke inkxaso ilogiweyo, kwaye abaxhasi abaqhelekileyo banokuba ngamalungu eqela le- DAO.
Fumana umsebenziZonke izinto apha zisimahla, kwaye ziya kuqhubeka zinjalo. Kusuka ngo-2017 abasunguli baqhuba le projekthi ngokwabo, ngenxa yothando olulula lokubonisa abantu izulu esibelana ngalo. Ukuba le ndawo ikunikeze into, inkxaso inceda ukugcina izifundo, izixhobo kunye nokukhangela okuvulekileyo kwingqondo elandelayo enomdla.
