Nakshatra is the position of the centre of the Moon in the
zodiac as seen from earth's centre. This is counted as degree from 0
Aries.  There are 27 Nakshatras and 12 Signs. So there will be 13.333
degrees in each Nakshatra and 30º in each sign. In the Rasi Chakra each square
is equal to 1 sign. There are 2¼ nakshatras in each sign. A nakshatra is called
an asterim or group of stars.  The navamsha chakra drawn has each square
equal to ¼ of a nakshatra = 1 paada = 1 charan =3.333 degrees.
