Based on the coordinates shown in the image, what is the declination of the star Arcturus?
The correct answer is b.
The declination of Arcturus is 19 degrees North. Interestingly, 19 degrees North is also the latitude of Hawaii. Why is this important? Find out by continuing through the pages ahead.
As you progress through the content, notice that the conventional format to express Earth coordinates is to write the zonal (north-south) value first: (latitude, longitude). Celestial coordinates typically express the meridional (west-east) value first: (GHA, declination).
