Heliocentric Julian Date

Rise and set time refer to the times when a celestial object, such as the Sun, Moon, or a star, appears to rise above the horizon (rise time) and when it sinks below the horizon (set time). These times are influenced by the observer's geographic location, the Earth's rotation, and the object's position in the sky. They are essential for astronomers and stargazers to determine when a celestial object will be visible. Rise and set times also vary throughout the year due to the Earth's tilt and orbit, leading to seasonal changes in daylight hours.
