Sample interview questions: Can you explain the concept of parallax and its significance in celestial navigation?
Sample answer:
Concept of Parallax
Parallax is the apparent shift in the position of an object when viewed from two different locations. In celestial navigation, parallax is the angular difference between the apparent position of a celestial body as seen from the observer’s location on Earth and its true position from the center of the Earth.
Significance in Celestial Navigation
Parallax plays a crucial role in celestial navigation as it:
- Provides Altitude Correction: Parallax causes the observed altitude of a celestial body to be lower than its true altitude. This correction is essential for accurate position calculations.
- Calculates Celestial Body Distances: Usingparallax, navigators can determine the distance to the Moon, planets, and even nearby stars through observations from different positions on Earth.
- Determines Earth’s Radius: Parallax measurements of the Moon from different latitudes allow for the calculation of the Earth’s mean radius.
