Sphere angular diameter=2 asin(radius/distance).
Symbols and units
- a
- Object diameter (same units as distance)
- b
- Distance to centre (same units)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Spherical object; observer outside sphere. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Spherical object; observer outside sphere.
