Celestial Sphere

The celestial sphere is divided into eat and west hemispheres by lines that run from pole to pole called ___.

• parallels

• meridians

• ecliptic

• equator

The celestial sphere turns once around each day because

• the planet on which we live is rotating

• the Earth is going around the Sun

• the phases of the Moon

• precession

• everything in the universe turns around the Earth

Let's say we find a star that is located on the points or circles in the sky listed in the answer choices below. Then, on the same night, we move to a location on Earth that is some significant distance from our first location. There will now be a different star at or on:

• the celestial north pole

• the zenith

• the celestial equator

• the celestial south pole

• all of the above

The south celestial pole and the north celestial pole lie in the sky directly above

• the Earth's equator

• the observer's zenith

• the ecliptic

• the Earth's axis

• the town of Bayonne, New Jersey

5. On the celestial sphere, halfway between the celestial poles lies the

• horizon

• zenith for all observers

• celestial equator

• path of the Sun on any given day

• celestial hungarian

Someone who observes the sky every clear night in Boston for many years will NEVER get to see:

• the south circumpolar zone

• the north celestial pole

• the observer's zenith point

• the north circumpolar zone

• the Big Dipper

15. The Sun's apparent path around the celestial sphere is called

• the horizon

• the circumpolar zone

• the celestial equator

• the celestial hot-zone

• the ecliptic
