Question

Quizplus · Accepted Answer

Right ascension (measured in hours, minutes, and seconds) and declination (measured in degrees) are the celestial coordinates that together describe a star's position precisely in our sky. Longitude and latitude are used to describe positions on Earth, while sidereal time is a measure of the Earth's rotation, but does not describe the position of a star.
