Cosmic scale
ConceptCosmic scale concerns the very different sizes, distances and times encountered in astronomy.
Explanation or usage
A planet, planetary system and galaxy occupy different levels of a physical hierarchy. Changing scale can make previously small differences significant or small structures hard to see. A scale model needs an explicit mapping between the model and the quantities represented.
Common misunderstandings
A star, its planetary system and its galaxy are the same kind of object.
