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.

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.
What is the distance measured in degrees north and south of the equator is referred to as?
Declination (positive and negative respectively) is the angular distance between north and south of the Celestial Equator.
What are the coordinates of Cygnus in degrees and hours?
Libra lies between the constellation Virgo to the west and Scorpius to the east, at about 15 hours 30 minutes right ascension (the coordinate on the celestial sphere analogous to longitude on the Earth) and 15° south declination (angular distance south of the celestial equator).
What is celestial hemisphere?
It half of the celestial sphere, which is an imaginary sphere with the Earth at the centre, on which all objects in the sky can have their positions described by a type of latitude (declination) and a type of longitude (right-ascension). Declination goes from -90 degrees (south) to +90 degrees (north), while right ascension goes from 0 to 24 hours. They are called geocentric coordinates, and although we know the Earth is not at the centre of anything, they are useful in describing where to look for a star or to point a telescope.
What is the term used to measure distance north and south of the Equator?
Declination measures the number of degrees north or south of the Celestial Equator.

What latitude is the sun directly overhead at noon on may 5th August 10th abd October 15th?
Anywhere where the declination of the Sun is equal to your latitude. You can look up the declination of the Sun in the Nautical Almanac. Declination is the angle of a celestial body north or south of the celestial equator; the celestial equator is the same as the terrestrial one, extended out into space. On June 21, the Sun's declination is about 23.5 degrees north; on the equinoxes, it is zero. On December 21, the Sun's declination is about 23.5 degrees south.

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.
When does the Sun have declination 0 degree today but will have a negative declination tomorrow?
Declination is the angular measurement of a celestial body north or south of the "celestial equator". You can think of it as the equivalent of "celestial latitude". The "fixed stars" don't have any change in declination. (Well, they _DO_, but only very slightly and VERY slowly.) The Sun, Moon, and planets all have their own paths within the solar system, so their declinations will change on a day-to-day basis. The Sun is at a declination of zero precisely at the time of the equinox. In September, the Sun's declination is decreasing, and it goes negative immediately after the moment of the equinox. This is generally on September 21, but this can vary a day either way depending on the cycle of leap years.
Is the full moon high or low in a June sky in the U.S.?
For the full moon to be especially high in the sky as viewed from North America, it must have a substantial north declination, as listed in the nautical almanac. Declination is the "apparent latitude" of a celestial body. (See the link below for the online nautical almanac.) The full moon in June 2010 was June 26. The Moon's declination was 24 degrees south. On June 15, 2011, (the date of the full moon) the Moon's declination will be 23 degrees south, so the full moon will be fairly low on the horizon as viewed from North America. In fact, I sampled a number of years, and the full moon of June generally has a substantial SOUTH declination. So, for those years, June's full moon is generally low in the sky.
What is a stars location determined by?
Astronomers use the coordinate system of RA right ascension also called hour angle, and Declination (Dec)RA is the celestial equivalent of terrestrial longitude. Both RA and longitude measure an east-west angle along the equator; and both measure from a zero point on the equator. For longitude, the zero point is the Prime Meridian; for RA, the zero point is known as the First Point of Aries, which is the place in the sky where the Sun crosses the celestial equator at the March equinox. RA is always zero on the meridian of the celestial sphere which passes through the celestial poles and first point of Aries. Declination is comparable to latitude, projected onto the celestial sphere, and is measured in degrees north and south of thecelestial equator. Therefore, points north of the celestial equator have positive declinations, while those to the south have negative declinations. * An object on the celestial equator has a dec of 0°. * An object at the celestial north pole has a dec of +90°. * An object at the celestial south pole has a dec of −90°.
What is the celestial pole?
The celestial poles are located directley above the Earth's north and south pole.
Latitude in a definition?
the angular distance of a place north or south of the earth's equator, or of a celestial object north or south of the celestial equator, usually expressed in degrees and minutes
