What do we use the Pisces constellation for, why is it important? need to know ASAP!?

could it be used for preedicting seasons, or for navigation?What do we use the Pisces constellation for, why is it important? need to know ASAP!?The 'Vernal Equinox' point lies in the constellation Pisces. The 'Vernal Equinox' is the crossing point of the 'Ecliptic' (Sun seems to move along this line between the stars in a year time) and the 'Equator' (cuts the daily turning star sky in half, parallel with earth's equator). It is at March 21 the Sun crosses this point, which means the start of Spring.



But this point is also used as a starting point for the 'Right Ascension', it is like a horizontal coordinate with values running from 0 to 24 hours to indicate the position of a star.



Further, this point is also used for the 'Local Siderial Time'. This is also an expression from 0 to 24 hours, showing which star sky is visible at that moment for that observer place. One says that the 'Local Siderial Time' is zero, when that 'vernal equinox point' (so Pisces) is culminating the highest (which is through South).What do we use the Pisces constellation for, why is it important? need to know ASAP!?It is one constellation of the Zodiac, the path of the sun among the stars.

Right now, the vernal equinox moves between the constellation's IAU official boundaries and the next constellation, Aquarius.

"The Vernal equinox is currently located in Pisces, due south of 蠅 Psc, and, due to precession, slowly drifting below the western fish towards Aquarius."What do we use the Pisces constellation for, why is it important? need to know ASAP!?Pisces is no more important than any other constellation, except that the ecliptic passes through it, so it often has planets and the Moon in it. Constellations are really just a convenient way of identifying stars and other objects in a particular area of the sky, and have no scientific meaning.
