Declination (noun)

Examples:

1. The declination of the star was measured to be 23.5 degrees.
2. The declination of the sun changes throughout the year due to the tilt of the Earth's axis.
3. The declination of the planet was used to calculate its position in the sky.
4. The declination is a measure of the latitude of a celestial object.
5. The declination of the moon was found to be different from that of the sun.
