When we say that a celestial body "sets at" a certain time or location, it means that it sinks below the visible horizon from that particular vantage point. This apparent movement occurs as the Earth rotates, causing different parts of the sky to become visible or hidden at different times.
The term "sets at" is often used in the context of time, highlighting the specific moment when a celestial body's descent below the horizon occurs. For example, one might say, "The Sun sets at 6:00 PM today," indicating that the Sun will disappear from view precisely at that time.
Furthermore, "sets at" can also refer to the location or direction at which a celestial body will vanish below the horizon. This information is particularly relevant for navigation or stargazing purposes, allowing individuals to anticipate the trajectory of a celestial object as it sets.
In conclusion, "sets at" is a phrase used to indicate the time or location when a celestial body, like the Sun or a star, disappears below the horizon when observed from Earth due to the rotation of the planet.
