The document defines several astrological terms:
- The ecliptic is the path of the sun. The meridian and equator intersect at different points as the ecliptic is inclined at an angle to the equator.
- The ascendant, 10th house, and 7th house are where the ecliptic intersects the eastern horizon, meridian, and western horizon.
- The angle between the ecliptic and equator is zero at the Aries and Libra first points and maximum at Cancer and Capricorn.
1. Astrology Terms
● Ecliptic longitude
● Ascendant
● Right Ascension
●
10th
House
● Aries First Point
● Mesha Rasi First Point
● Ayanamsha
2. ● Ecliptic is the path of Sun.
● Meridian is a great circle on the vertical plane
about NS line at your place. It has Zenith, the
vertical point, the North(South)pole , N and S
apart from 10th
house.
●
Ascendant ,10th
house. 7th
house are points
where ecliptic meets Eastern Horizon, Meridian
and Western Horizon respectively.
● Equator is inclined to Horizontal Plane by an
angle of Latitude of the place.
●
3. ● All points on Equator rise at E, touch the
meridian at Eq and set at W.
● Points on Ecliptic Ecl touch the Meridian at
different points. The distance of Ecl from Eq
along Meridian varies between +23.45o
to
-23.45o.
● Angle between Ecliptic point and Equator point
Eq is zero at Aries and Libra 1st
points.
●
Angle is +23.45o
and -23.45o
when Cancer and
Capricorn 1st
points touch Meridian.

Meridian is on vertical plane about NS; Zenith is
vertical point above the place; Meridian cuts
equator at point Eq; Latitude is the angle
between EW vertical plane and Equator
(angle ZOEq); Ecliptic is inclined to Equator by
an angle =obliquity (angle EqOEcl)of 23.45o
.
Ecliptic touches meridian at 10th
house,and
horizontal plane in east at ascendant(1st
house)
and 7th
house in west. Sun moves in ecliptic
plane. Ecliptic and Equator meet at Aries and
Libra first points.
