How to Calculate Angular Separation Between Two Stars

Learn to find the angular separation of stars using tools, formulas, and astronomical methods effectively.

0 views

To find the angular separation of two stars, use a tool like a star chart or an astronomical software. Measure the angle between the two stars' positions in the sky in degrees or arcminutes. Alternatively, use the formula: angular separation = arccos(sin δ1 sin δ2 + cos δ1 cos δ2 * cos(α1 - α2)), where δ1 and δ2 are the declinations and α1 and α2 are the right ascensions.
