In the vast reaches of space, where the stars serve as our compass, celestial navigation tools play a crucial role in guiding explorers through the cosmic expanse. Among these tools, the sextant stands out as a timeless instrument, connecting ancient navigational traditions with modern space exploration. Join us as we unravel the mysteries of sextants, exploring their purpose and unveiling the top 10 picks for enthusiasts and spacefarers alike.

What is a Sextant and Its Purpose?

A sextant is a precision instrument used in celestial navigation to measure the angle between two celestial objects, typically the horizon and a celestial body such as the Sun, Moon, or stars. This measurement, known as the altitude, helps navigators determine their position on Earth. In the context of space exploration, sextants are valuable tools for aligning spacecraft and ensuring accurate trajectories.

Key Features of a Sextant:

• Reflecting mirrors: Sextants use mirrors to capture and measure the angle between the horizon and a celestial body accurately.

• Arc and scale: The instrument features an arc with a scale to read the measured angle, allowing for precise navigation calculations.

• Index arm and micrometer drum: These components facilitate fine adjustments to the angle measurement.
