Solid angles are often used in astronomy, physics, and in particular astrophysics. The solid angle of an object that is very far away is roughly proportional to the ratio of area to squared distance. Here "area" means the area of the object when projected along the viewing direction. See more In geometry, a solid angle (symbol: Ω) is a measure of the amount of the field of view from some particular point that a given object covers. That is, it is a measure of how large the object appears to an observer looking … See more • Defining luminous intensity and luminance, and the correspondent radiometric quantities radiant intensity and radiance • Calculating spherical excess E of a spherical triangle See more • Jaffey, A.
