Answer 1

Answer:

1) Zenith is the imaginary point that is directly above a particular location on the celestial sphere. The opposite of zenith, that is the direction of the gravitational pull, is called the Nadir, at 180 degrees. ... Zenith, in astronomy terms, is the point in the sky directly overhead.

2) the point of the celestial sphere that is directly opposite the zenith and vertically downward from the observer.

3)each of the two points in which the extended axis of the earth cuts the celestial sphere and about which the stars seem to revolve.

4)A (geographic) meridian (or line of longitude) is the half of an imaginary great circle on the Earth's surface, terminated by the North Pole and the South Pole, connecting points of equal longitude, as measured in angular degrees east or west of the Prime Meridian.

5)celestial equator is the great circle in which the plane of the terrestrial Equator intersects the celestial sphere; it consequently is equidistant from the celestial poles.

6)The ecliptic is the plane of Earth's orbit around the Sun. From the perspective of an observer on Earth, the Sun's movement around the celestial sphere over the course of a year traces out a path along the ecliptic against the background of stars.

7)There are 12 astrological signs, also known as signs of the zodiac. In order, they are - Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. Some people believe that different signs of the zodiac reveal a person's different characteristics and talents.

8)Nakshatra (Sanskrit: नक्षत्र, IAST: Nakṣatra) is the term for lunar mansion in Hindu astrology and Indian Astronomy. A nakshatra is one of 28 (sometimes also 27) sectors along the ecliptic. Their names are related to a prominent star or asterisms in or near the respective sectors.
