Does The celestial equator always pass directly overhead?
No, the celestial equator does not always pass directly overhead. The position of the celestial equator in the sky is determined by the observer's latitude on Earth. If the observer is located at the equator, the celestial equator will pass directly overhead. However, for observers at different latitudes, the celestial equator will appear at an angle to the horizon.
What is the difference between the celestial equator and the horizon?
The celestial equator is an imaginary line in the sky that represents the projection of Earth's equator onto the celestial sphere. It divides the sky into northern and southern hemispheres. The horizon, on the other hand, is the line where the sky meets the Earth's surface when viewed from a specific location, forming the boundary between the visible sky and the ground.
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.
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.
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.
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
What invention measured the angle between a celestial body and the horizon?
Sextant
What is the great circle on the sky midway between the celestial poles is called?
The horizon is the great circle on the sky midway between the celestial poles.
What latitude on earth is a celestial pole 45 above the horizon'?
At 45 degrees north latitude, the north celestial pole appears 45 degrees above the northern horizon. At 45 degrees south latitude, the south celestial pole appears 45 degrees above the southern horizon.
Why can you see the sky from the north pole to the equator when you can only see a few miles of water to the horizon and you can't see airplane tracks that far away - I do not understand this?
What, exactly, did you see? - You can basically see anything for which you have line-of-sight, that is, if a straight line between the object and you doesn't go below the horizon. I think the questioner may be mixing up the "celestial equator" and the Earth's equator. The celestial equator is the "projection" of the Earth's equator onto the sky. It a great distance away, effectively at infinity. Let's consider the difference between the two equators. Normally, you can see only a few miles to the horizon, depending on your height above your surroundings. Obviously you can't see the Earth's equator from the North Pole. Things above ground such as airplane tracks can be seen when they are further away than the horizon, but still your visibility is limited by the Earth's surface. However, from the North Pole, you can see as far south in the sky as the celestial equator. So, you could just about see a star in that part of the sky. The stars are light years away, of course. Imagine you are near a distant star on the celestial equator. In theory, at that distance, you could see one full hemisphere of the Earth from pole to pole. So, someone at the Earth's North Pole could see that star. To sum up: it's because the stars are so far away that you can see a star on the celestial equator from the North Pole.
