question 19 of 19 observable properties derived or calculated properties answer bank proper motion intrinsic luminosity color distance mass apparent magnitude size

Explanation:

Observable properties are directly measurable. Proper motion, color, and apparent magnitude can be directly observed. Derived or calculated properties require additional calculations or models. Intrinsic luminosity, distance, mass, and size are determined through various astrophysical relationships and calculations.

Answer:

Observable properties: proper motion, color, apparent magnitude
Derived or calculated properties: intrinsic luminosity, distance, mass, size
