What else can I help you with?
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.
What is the star latitude and star declination?
Celestial coordinates. -- The star's latitude on the celestial sphere is the same as the Earth latitude that it seems to follow on its way aroujnd the sky. On the celestial sphere, the latitude is called "declination", and is expressed in degrees. -- The star's longitude on the celestial sphere is its angle, measured westward, from the point in the sky called the Vernal Equinox ... the point where the sun appears to cross the celestial equator in March. On the celestial sphere, the star's longitude is called "Right Ascension", and it's expressed in hours. That certainly seems confusing, but an "hour of Right Ascension" just means 15 degrees of celestial longitude. So, as the sky turns, the point directly over your head moves through the stars by 1 hour of Right Ascension every hour.
How can one determine the declination of a star?
To determine the declination of a star, one can use a tool called a star chart or a star atlas. By locating the star in the night sky and referencing its position relative to the celestial equator, one can measure the angle of the star's position above or below the equator to find its declination.
From what location on Earth is the The celestial equator not visible?
The north celestial pole is not visible from any point on Earth's surface south of the equator. This is always true. The north celestial pole is the point in the sky directly above the Earth's north pole. Even though the north celestial poles moves about in the sky, it remains invisible everywhere in the southern hemisphere. The north celestial pole moves around in a circle in the sky as the Earth's axis wobbles. Each wobble takes about 23 thousand years.
Is the north star a star or a planet?
I think the answer is in the question. North Star!! It's a star called Polaris
Is the north star north of the celestial equator?
Yes. The North Star is aligned with the celestial north pole.
Does a star that is located 30 degrees north of the celestial equator have 30 degrees declination?
Yes. "Declination" on the celestial coordinate system is the counterpart of "latitude" on the terrestrial coordinate system. Positive and negative declination correspond respectively to north and south latitude.
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?

What is the celestial pole?
The celestial pole is the point in the sky directly above the Earth's North or South Pole. The North Celestial Pole is located near the North Star (Polaris), while the South Celestial Pole does not have a bright star near it. Stars appear to rotate around these points due to Earth's rotation.
In the horizon coordinate system altitude-azimuth how many degrees does a star at the celestial equator move in 1 hour and how many arcseconds does the star move in 1 second of time?
A star at the celestial equator will move 15 degrees in altitude per hour, and 15 arcseconds in 1 second of time. This is because the celestial equator intersects the celestial sphere at 90 degrees from the north and south celestial poles, so the stars appear to move in circles around the celestial poles.
What star is located right above the north pole?
Polaris, also called the North Star and the Pole Star, is situated within about 2/3 of a degree of the North Celestial Pole.

If you were standing at the earths north pole which would be located in the zenith?
If you were standing at Earth's North Pole, the North Star, also known as Polaris, would be located directly in the zenith, or straight overhead. This is because Polaris is situated very close to the celestial north pole in the night sky.
Is the north star a star or a planet?
I think the answer is in the question. North Star!! It's a star called Polaris
Is The south celestial pole is located at a declination of -90 degrees?
The Celestial Poles are the infinite extension of the North and South Poles from the Earth into space. The North Star or Polaris, is within 1 degree of the North Celestial Pole. There is no equivalent star for the South Celestial Pole.
