Does The celestial equator always pass directly overhead?
If you are standing at the north or south pole, then the celestial equator coincides with your horizon. At other latitudes, half of the celestial equator is above the horizon, and half is below it.
When you observe a star on the celestial equator for a period of a few hours what can you notice?
moves from east-to-west relative to the horizon
How do you determine the altitude at which the celestial equator cuts the meridian?
The altitude at which the celestial equator intersects your local meridian is the complementof your latitude, i.e. the difference between your latitude and 90 degrees.On the equator: Your latitude is zero. (90 - 0) = 90. Celestial equator passes overhead.At the pole: Your latitude is 90. (90 - 90) = 0. Celestial equator coincides with the horizon.In New Orleans, Louisiana, or Durban, South Africa: Your latitude is 30. (90 - 30) = 60.Celestial equator intersects local meridian at 60 degrees above the horizon.
What is the projection of earths equator on the celestial sphere?
Celestial Equator
When you observe a star on the celestial equator for a period of a few hours you notice what?
You will notice that the angle makes with respect to the horizon. Typically, you will find that the angle will be 90 minus the latitude of the observer.

What is the difference between the celestial equator and the horizon?
The celestial equator ties our planet to constellations. Humans perceive the horizon from the ground, so it appears curved to our naked eye.
What are some similarities between the celestial equator and the horizon?
yes
The celestial equator always crosses the horizon at the east point and west point?
This is true. The celestial equator ... the line of zero declination ... crosses the horizon due east and due west. However, the ecliptic ... the apparent path of the sun through the stars ... is inclined to the celestial equator, and can hit the horizon anywhere within 23.5 degrees north or south of the east-west directions, depending on the time of day and day of the year.
Can you see the north celestial pole from the US?
Yes. For any point on Earth that is north of the equator, the north celestial pole is above the horizon.
If you were standing on the earth's equator where would you look to see the north celestial pole Could you see it from Australia?
At the equator, the celestial north pole would be north, just at the horizon. In the southern hemisphere, for instance in Australia, the north celestial pole would be north, and as many degrees BELOW the horizon as your latitude. For instance, if you are 10 degrees south of the equator, the celestial north pole would be 10 degrees below the equator.On the other hand, for people in the southern hemisphere, the celestial SOUTH pole would be ABOVE the horizon; this same pole is below the horizon for anybody in the northern hemisphere.

If you were located on the Earth's equator and were observing the nighttime sky you would find the North Celestial Pole lying at on your?
If you are at the equator, the Earth's celestial pole would be at the northern horizon. However, because of atmospheric haze, you would not be able to see Polaris. Below about 5 degrees north, Polaris is not visible.
Halfway between the celestial poles lies the?
