Instructions:
This calculator may be used to calculate the angular distance between two stars or celestial objects.

Star 1 Right Ascension: Enter the Right Ascension of the first star in hours. You can enter this as HH.MMSS and click "Convert HH.MMSS" to convert to hours
Star 1 Declination: Enter the Declination of the first star in degrees. You can enter this as DDD.MMSS and click "Convert DDD.MMSS" to convert to degrees.
Star 2 Right Ascension: Enter the Right Ascension of the second star in hours. You can enter this as HH.MMSS and click "Convert HH.MMSS" to convert to hours
Star 2 Declination: Enter the Declination of the second star in degrees. You can enter this as DDD.MMSS and click "Convert DDD.MMSS" to convert to degrees.
Calculate: When you have entered and converted all your inputs to the proper units, click "Calculate." The angular distance will be calculated and displayed as degrees and degrees/minutes/seconds in the fields below.
