Write a note on Nakshatra.

An imaginary sphere covering the sky with the earth at its center is known as the celestial sphere. The ecliptic of the celestial sphere is divided into 27 equal parts, which is known as Nakshatra.

The angular displacement of each Nakshatra can be found by dividing the whole sphere i.e. 360 by 27 (360/27) we get 13⁰20’ (thirteen degrees twenty minute).

Since moon takes 27 days to complete one revolution around the earth that means moon remain in one nakshatra for a day while sun remains for 13.5 days (365/27).

Additional Information:

Nakshatra is also given names based on imaginary figure formed by joining stars.
