The distances between the stars scattered throughout space are enormous. Even
in our solar system, which is the name given to the sun and the planets,
distances are very large. If we represented the Earth by a golf ball, the sun
would be equivalent to a sphere 4.5 metres across and nearly 0.5 km away. In
fact the distance between the Earth and the sun is about 150,000,000 km. This
distance, called an astronomicle unit, is sometimes used as a unit of
measurement in astronomy. An even larger unit is the light-year, which is the
distance travelled by light in one year; it is equal to about 9.5 million
million km.
The galaxy to which our solar system belongs is called the Milky Way. It is a
whirling wheel of stars, some 100,000 light years across and 10,000 light years
thick. Our nearest neighbouring galaxy, Alpha-Centauri, is 40 million million
km away.
