The asterism called the "Big Dipper" (which is the central part of the constellation named "Ursa Major") has two fairly prominent stars which act as a pointer to the north star Polaris. Polaris is a relatively dim and undistinguished star whose positioning almost directly above the north pole is very conveniently located in the sky.
The altitude of Polaris is roughly equal to your north latitude. Your longitude has no effect on it.At 35 degrees south latitude, the altituide of Polaris is negative 35 degrees. In other words,it's 35 degrees below the point on the horizon due north of you, and you can't see it.
First, we need the "transit altitude" of the celestial equator, at 80 degrees north. That's 90 - 80 degrees = 10 degrees. At noon (local apparent noon) the Sun's altitude will be: 10 degrees + the Sun's declination. That's the altitude of the Sun's "upper culmination". At "midnight" (the Sun's "lower culmination") the Sun's altitude will be: the Sun's declination - 10 degrees. So, the difference in altitude is 20 degrees. The Sun is 20 degrees higher at noon.
The North Pole is at 90 degrees north latitude, and the South Pole is at 90 degrees south latitude. So, distance north or south of the equator is called 'latitude'. One way to remember this is to think of the rungs of a ladder. "Ladder"-- "Lati-" you step up or down the 'rungs of ladder-tude'.
The "North Celestial Pole" of the sky is always due north of you, and at the same angle above your horizon as whatever your north latitude is. It doesn't move, and the north star is always within about 1/3 of a degree from that point. Your longitude makes no difference at all. And neither does the time of day. And feet and inches have no place in angle measure. And latitude is north or south and longitude is east or west.
Houston is located at the following: 29° 45' North (Latitude). 95° 22' West (Longitude).
The azimuth of the North Celestial Pole is zero ... it's due North. The altitude of the North Celestial Pole is the same as your north latitude. In mid-town Manhattan, that's about 42.6 degrees.
The altitude of the North Celestial Pole above the northern horizon is equal to the observer's latitude. This means that the higher the observer's latitude, the higher the North Celestial Pole will appear in the sky. For example, an observer at a latitude of 45 degrees will see the North Celestial Pole 45 degrees above the northern horizon.
Maximum inclination of moon's orbit to the ecliptic = 5.3°Current inclination of the ecliptic to the celestial equator = 23.4°Moon's maximum declination = 5.3° + 23.4° = + 28.7°Maximum altitude of the celestial equator at 42° north latitude = 90° - 42° = 48°Moon's maximum altitude at 42° north latitude = 48° + 28.7° = 76.7°
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 your latitude is 39 degrees north, then the north celestial poleis 39 degrees above your northern horizon.If your latitude is 39 degrees south, then the north celestial poleis 39 degrees below your northern horizon.
The altitude of the celestial north pole above the northern horizon is exactlythe observer's north latitude on the earth. The center of Frankfurt is very closeto 50° North latitude.
If the altitude of Polaris is 43 degrees above the northern horizon, then the observer is located somewhere within roughly 1/2 degree of 43 degrees north latitude.
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.
Any sky object within (your latitude) degrees of the north celestial pole.
North of the equator. In theory, about 0 degrees, or further north.
Fairbanks is located at latitude 64.8 degrees north, so the north celestial pole is always 64.8 degrees above the horizon. Polaris itself is presently about 0.7 degrees from the celestial pole, so its altitude above the horizon will vary between 64.1 and 65.5 degrees during the course of a sidereal day.
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.
