Note: Distance measurements on an astronomical scale, which go well past the Solar System and the immediate neighbourhood of the sun, are in many cases possible with astounding accuracy, but sometimes - also depending on the type of object - controversial.
Different sources may publish different values, but on a bigger scale, there is widespread agreement about the distances of most objects.
