Ko te whetū e amio haeretia ana e Papatūānuku me ngā aorangi e noho whanaunga mai ana. He poi te āhua o te Rā, 1.4 miriona kiromita te whitianga. He mea hanga ki ngā haurehu nei, te hauwai (H) me te haumāmā (He). Ko te tō ā-papa e pupuri ana i ngā haurehu ki te āhua o te poi. He tauhohe karihi e haere ana i roto i te Rā, ina te huri o te hauwai (H) hei haumāmā (He). Kāore e ārikarika te pūngao ka hua ake i ngā tauhohe karihi nei, he pūngao pōkākā. Ka eke te paemahana o te iho o te Rā ki te 14 miriona tākiri tohurau (14,000,000°C). Ka hahana mai te pūngao nei hei pūngao autōhiko.
The star which is orbited by the Earth and other planets of the Solar System. The Sun is spherical in shape with a diameter of 1.4 million kilometres. It is composed of the gases hydrogen and helium. The force of gravity keeps the gases in a spherical shape. Nuclear reactions occur inside the Sun which change hydrogen into helium. This produces vast amounts of heat energy. The interior of the Sun reaches a temperature of 14 million degrees Celcius. This energy is radiated out as electromagnetic energy.

He aha i puta mai ai he pūngao pōkākā i a Tamanuiterā?
Ko Tamanuiterā te pūtakenga matua o ngā momo pūngao katoa.
