... A star's position along a circle of constant declination is described by a second number called right ascension. Right ascension corresponds to longitude, but different units are used. Instead of 360°, a circle is broken into 24 hours of right ascension. So, 360° = 24 h R.A., 15° = 1 h R.A., and 1° ...
