Meridian circle is an instrument used in astronomy to measure the exact position of stars and other celestial objects in the sky. It consists of a large circle, usually mounted horizontally, with a telescope at its center.
The meridian circle is aligned with the local meridian, which is an imaginary line that runs from the north celestial pole to the south celestial pole, passing directly overhead. This allows astronomers to measure the altitude and azimuth of celestial objects as they cross the observer's meridian.
Function
When an object is observed through the telescope of a meridian circle, the observer can make precise measurements of its position in the sky. By recording the object's altitude and azimuth at a specific time, astronomers can accurately determine its celestial coordinates.
Accuracy
Meridian circles are known for their high level of accuracy, making them essential tools for astronomical observations. They allow astronomers to track the motion of celestial objects with great precision and monitor changes in their positions over time.
Meridian circles have been used for centuries to create star catalogs, measure the positions of planets and moons, and study the movements of comets and asteroids. They continue to play a vital role in modern astronomy, enabling astronomers to map the night sky with incredible detail.
