What is an octant?
One eighth of a circle.
How many degrees are there in an octant?
There is 45 degrees in an octant. This is equivalent to one eighth of a circle. Since a circle has 360 degrees you would divide this number by 8.
What is one eighth of a circle called?

What does a sextant replace?
A similar but smaller instrument called the octant. The octant was one eighth ("octo" is latin for eight) of a circle, while a sextant ("sextus" is Latin for "six") is one sixth of a circle. An even earlier instrument was called a quadrant. Enter your guesses as to how big a "quadrant" is in the Discussion area!
What is 1 8th of a circle is called because 1 4th is called quadrant?

What is the story behind octans constellation name?

The octant wasn't big enough for detailed navigation, so a bigger instrument that was one-sixth of a circle - the "sextant" - replaced it.
Who invented the octant?
Robert Hooke invented the octant in 1684
What year was the octant built in?
Isaac Newton invented the reflecting octant in 1699.
When did people start using sextants?
When navigators wanted to be able to measure angles that were larger than about 60 degrees and the older octant wasn't long enough to do it. An octant has an arc of one eighth of a circle. (From the Latin prefix "octo" for eight.) The device uses a mirror as a doubling tool, so in theory an octant could measure one fourth of a circle, or 90 degrees, but there's some overlap in the mechanism and you don't get the full 90 degrees. The sextant is one-SIXTH of a circle (Latin "sextus" for six), and with doubling (and the overlap) allows you to measure more than 90 degrees.
What is OCTANT RULE?
Octant rule is the one which is used to correlate the sign of the cotton effect.
