WhakamĀrama Āpitihanga
Hei tātai i te rahi o tētahi tau aho:
Te tawhiti o te whātoro atu o te aho i te tau kotahi. Ka eke tēnei ki te 9.46 miriona miriona (piriona) kiromita (9.46 x 1012km). Ka whakamahia te tau aho hei whakaatu i ngā tawhiti nui tonu o te ātea. Hei tauira, ko te tawhiti mai i tētahi taha o te ikarangi o Te Mangōroa ki tētahi, kei te takiwā o te 100,000 tau aho.
The distance light travels in a year. This is equivalent to 9.46 million million (billion) kilometres (9.46 x 1012km). The light year is used to show the vast distances in space. For example, the distance across The Milky Way galaxy is about 100,000 light years.
