This yellow star is truly the heart if our planetary system. The distance between our small planet and the giant star is enormous – according to the astronomical data, it is about 92,955,800 mi! Impressive, isn't it? It is an interesting fact that astronomers use the term "astronomical unit" (1 AU) to define the distance between our planet and the Sun. Obviously, 1 AU is equal to this distance.
