The sextant was developed in the 18th century, with significant contributions from several inventors. The first practical sextant is attributed to British instrument maker John Hadley, who created a working model around 1730. However, the design was also influenced by earlier navigational instruments such as the quadrant and the astrolabe. The sextant became widely used by sailors for celestial navigation, allowing them to measure the angle between a celestial body and the horizon.

Where was the sextant invented?
The sextant was invented in England in the early 18th century, with its design being attributed to John Hadley and Thomas Godfrey independently. The device quickly became a crucial tool for navigation at sea due to its accuracy in measuring angles between celestial objects.
What century was the sextant invented?
The sextant was invented in the 18th century, with its development attributed primarily to the work of John Hadley and Thomas Godfrey in the 1730s. This navigational instrument allowed sailors to measure the angle between celestial bodies and the horizon, significantly improving maritime navigation. The sextant evolved from earlier instruments like the quadrant and astrolabe, and it became an essential tool for navigation at sea.
What is the purpose of the horizon shades on a sextant?
The horizon shades on a sextant are used to block out excess light from the sun or other bright sources on the horizon, making it easier to take accurate measurements of celestial objects such as stars or planets. They help to reduce glare and improve visibility when using the sextant for navigation or celestial observations.
What 1700th century explorers used the sextant?
Explorers in the 1700s such as James Cook and Antoine de Bougainville used the sextant for celestial navigation during their voyages. This tool helped them determine their position at sea by measuring the angle between the horizon and a celestial body, such as the sun or stars.

Is Tycho Brahe a girl or boy?
A Man. the Danish astronomer spent many years computing star positions and is said to have invented or improved the Sextant. We used to think it was a funny quote- Tycho Brahe ( pronounced Bra) invented the Sextant- accents on first sylabbles! He also discovered Tycho"s Star- probably a supernova which was visible Day and Night for over a year!
