'S e planaid a tha anns an Talamh, a' Chruinne no an t-Saoghal, air a bheil sinn a' fuireach. Tha aon ghealach aige agus 's e treas ball de rian na grèine.

Tha na cuain (sa bheil sàl) a' cuibhrigeadh mu deidhinn 70% de barr na talmhainn. 'S e tìr (talamh tioram) a tha anns an 30% eile. Tha aille a' cuairteachadh na talmhainn. Canar an adhar ris an àile seo.

Tha an talamh a' cuairteachadh na grèine aig astar 93,000,000 mìltean (1.6 km = 1 mìle). Canaidh sinn bliadhna ris an ùine a tha i a' gearradh gach cuairt.

Air barrachd an sin bithidh an talamh còmhnaidh na tionndadh mu deidhinn "aiseal" a ruitheas tro meadhan a tomaid. Is e an tionndadh seo, a bhitheas a' toirt 24 uairean a dh'adhbharaicheas latha agus oidhche
