The figure shown above is a map of the stars in relation to the sun. The yellow ball in the center is the sun, and the stars are marked on the orbitals surrounding the sun. The farther a star is from the center, the farther it is from the sun. This is a good way of giving a spatial description of a part of the solar system we can not see.
