Contents

Reference · The sky out to a distance, in layers: the stars and galaxies nearer than 10, 50, 100, 500 or 1,000 light-years, each distance band its own colour, the ones with an uncertain distance kept apart, and none placed at a guess

Certaintytype

How well a distance is known: good (under 5%), fair (5% to 20%) or rough (over 20%, or no error stated). A rough distance is never drawn at its best value: it is in the uncertain band, with its range.
